ASTM F3110-14(2024)(Practice)
Standard Practice for Proper Use of Mechanical Trenchless Point Repair Sleeve with Locking Gear Mechanism for Pipes of Varying Inner Diameter and Offset Joints

SIGNIFICANCE AND USE
4.1 This practice is for use by design engineers, specifiers, regulatory agencies, owners, installers, and inspection organizations who are involved in the rehabilitation of pipes through the use of a Mechanical Trenchless Point Repair Sleeve with a Locking Gear Mechanism for Pipes of Varying Inner Diameter and Offset Joints within a damaged existing pipe.  
4.2 This practice applies to the following types of defects in pipe that can be repaired: longitudinal, radial and circumferential cracks, fragmentation, leaking joints, displacement or joint misalignment, closing or sealing unused laterals, corrosion, spalling, wear, leaks in the barrel of the pipe, deformation in the pipe and root penetration. There are no limitations on the diameters of the laterals that can be sealed. The degree of deformation that can be repaired is dependent on the minimum and maximum diameters for which the sleeve is applicable as listed in the tables of dimensions shown in Appendix X1 but shall never exceed 5 %.  
4.3 This practice applies to pipes made of vitrified clay, concrete, reinforced concrete, plastics, glass reinforced plastics, cast iron, ductile iron and steel for both pressure and non-pressure applications.  
4.4 In this practice, no issues of snagging waste or build-up of sludge or sediment have been recorded to date; the performance of this sleeve, however, depends on many factors; therefore, past operational records may not include all possible future conditions under which the user may install these sleeves.  
4.5 The suitability of the technology covered in this practice for a particular application shall be jointly decided by the authority, the engineer and the installer.
SCOPE
1.1 This practice establishes minimum requirements for good practices for the materials and installation of mechanical trenchless repair sleeve with a locking gear mechanism for pipes of varying inner diameter and offset joints in the range of 6 in. to 72 in. (150 mm to 1800 mm).  
1.2 This practice applies to storm, potable water, wastewater and industrial pipes, conduits and drainage culverts.  
1.3 When the specified materials are used in manufacturing the sleeve and installed in accordance with this practice, the sleeve shall extend over a predetermined length of the host pipe as a continuous, tight fitting, corrosion resistant and verifiable non-leaking pipe repaired using one or more pieces of the repair sleeve mechanism. The maximum internal pressure this sleeve can carry depends on the diameter and the wall thickness, ranging from 10 to 15 bars; the external pressure shall not exceed 1.5 bars.  
1.4 All materials in contact with potable water shall be certified to meet NSF/ANSI 61/372.  
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Particular attention is drawn to those safety regulations and requirements involving entering into and working in confined spaces.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Phased Array Ultrasonic Testing of Polyethylene Electrofusion Joints

SIGNIFICANCE AND USE
5.1 This practice is intended for the semi-automated or automated ultrasonic examination of electrofusion joints used in the construction and maintenance of polyethylene piping systems.  
5.2 Polyethylene piping has been used instead of steel alloys in the petrochemical, power, water, gas distribution, and mining industries due to its reliability and resistance to corrosion and erosion.  
5.3 The joining process can be subject to a variety of flaws including, but not limited to: lack of fusion, cold fusion, particulate contamination, inclusions, short stab depth, and voids.  
5.4 Polyethylene material can have a range of acoustic characteristics that make electrofusion joint examination difficult. Polyethylene materials are highly attenuative, which often limits the use of higher ultrasonic frequencies. It also exhibits a natural high frequency filtering effect. An example of the range of acoustic characteristics is provided in Table 1.6 The table notes the wide range of acoustic velocities reported in the literature. This makes it essential that the reference blocks are made from pipe grade polyethylene with the same density cell class as the electrofusion fitting examined. (A) A range of velocity and attenuation values have been noted in the literature (1-9).  
5.5 Polyethylene is reported to have a shear velocity of 987 m/s. However, due to extremely high attenuation in shear mode (on the order of 5 dB/mm (127 dB/in.) at 2 MHz) no practical examinations can be carried out using shear mode (6).  
5.6 Due to the wide range of applications, joint acceptance criteria for polyethylene pipe are usually project-specific.  
5.7 A cross-sectional view of a typical joint between polyethylene pipe and an electrofusion coupling is illustrated in Fig. 1.
FIG. 1 Typical Cross-Sectional View of an Electrofusion Coupling Joint
SCOPE
1.1 This practice covers procedures for phased array ultrasonic testing (PAUT) of electrofusion joints in polyethylene pipe systems. Although high density polyethylene (HDPE) and medium density polyethylene (MDPE) materials are most commonly used, the procedures described may apply to other types of polyethylene.  
Note 1: The notes in this practice are for information only and shall not be considered part of this practice.
Note 2: This standard references HDPE and MDPE for pipe applications defined by Specification D3350.  
1.2 This practice does not address ultrasonic examination of butt fusions. Ultrasonic testing of polyethylene butt fusion joints is addressed in Practice E3044/E3044M.  
1.3 Phased array ultrasonic testing (PAUT) of polyethylene electrofusion joints uses longitudinal waves introduced by an array probe mounted on a zero degree wedge. This practice is intended to be used on polyethylene electrofusion couplings for use on polyethylene pipe ranging in diameters from nominal 4 in. to 28 in. (100 mm to 710 mm) and for coupling wall thicknesses from 0.3 in. to 2 in. (8 mm to 50 mm). Greater and lesser thicknesses and diameters may be tested using this standard practice if the technique can be demonstrated to provide adequate detection on mockups of the same geometry.  
1.4 This practice does not specify acceptance criteria.  
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Practice for Conventional Pulse-Echo Ultrasonic Testing of Polyethylene Electrofusion Joints

SIGNIFICANCE AND USE
5.1 This practice is intended primarily for the manual ultrasonic scanning of electrofusion joints used in the construction and maintenance of polyethylene piping systems.  
5.2 Polyethylene piping has been used instead of steel alloys in the petrochemical, power, water, gas distribution, and mining industries due to its reliability and resistance to corrosion and erosion.  
5.3 This practice is not intended to provide 100 % joint examination. This practice specifies a minimum scanning grid that represents only a portion of the welded interface. As such, there exists a possibility of omitting flaws. In addition, selected areas of the welded interface may not be accessible. The extent of examination shall be specified in the contractual agreement.  
5.4 The joining process can be subject to a variety of flaws including, but not limited to, lack of fusion, particulate contamination, short-stab depth, inclusions, and voids.  
5.5 Polyethylene material can have a range of acoustic characteristics that make electrofusion joint examination difficult. Polyethylene materials are highly attenuative, which often limits the use of higher ultrasonic frequencies. It also exhibits a natural high frequency filtering effect. An example of the range of acoustic characteristics is provided in Table 1.6 The table notes the wide range of acoustic velocities reported in the literature. This makes it essential that the reference blocks are made from pipes with the same Specification D3350 density cell classification as the electrofusion fitting examined. (A) A range of velocity and attenuation values have been noted in the literature (1-9).  
5.6 Polyethylene is reported to have a shear velocity of 987 m/s. However, due to extremely high attenuation in shear mode (on the order of 5 dB/mm [127 dB/inch] at 2 MHz) no practical examinations can be carried out using shear mode (6).  
5.7 Due to the wide range of applications, joint acceptance criteria for polyethylene pipe are usually ...
SCOPE
1.1 This practice establishes a procedure for ultrasonic testing (UT) of electrofusion joints in polyethylene pipe systems. This practice provides one ultrasonic examination procedure for ultrasonic pulse-echo straight beam contact testing, using straight-beam longitudinal waves introduced by direct contact of the search unit with the material being examined.  
1.2 The practice is intended to be used on polyethylene electrofusion socket (for example, couplings) and saddle (for example, tees) fittings for use on polyethylene pipe ranging in diameters from nominal 0.5 in. to 12 in. [12 mm to 300 mm] with pipe dimension ratios (DR) ranging from 6.3 to 17. Greater and lesser thicknesses and greater and lesser diameters may be tested using this practice if the technique can be demonstrated to provide adequate detection on mockups of the same wall thickness and geometry.  
1.3 This practice does not address ultrasonic examination of butt fusions. Ultrasonic testing of polyethylene butt fusion joints is addressed in Practice E3044/E3044M.
Note 1: The notes in this practice are for information only and shall not be considered part of this practice.
Note 2: This standard references HDPE and MDPE materials for pipe applications defined by Specification D3350.  
1.4 This practice does not specify acceptance criteria. Refer to Specification F1055 and Practice F1290 for destructive acceptance criteria.  
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

ASTM F3124-23a(Practice)
Standard Practice for Data Recording the Procedure used to Produce Heat Butt Fusion Joints in Plastic Piping Systems or Fittings

SIGNIFICANCE AND USE
5.1 The Device record includes information about how the heat butt fusion joint was made (heater temperature, pressures and times for the heating, fusion and cooling steps) and other important information about the process, job, equipment used, etc. The Device record is compared to the specified heat butt fusion procedure parameters to determine if the procedure was followed correctly. For comparison purposes, a graph of time versus pressure is generated from the data record to show pressure changes that occur during the butt fusion process. Comparing the time versus pressure graph to the steps in the procedure helps determine that the procedure parameters were observed, (Note 1). (See Appendix X1.) These records may be downloaded from the device and stored.  
5.2 When used in conjunction with manually-operated machines, the Device records information about the procedure used, the operator, the equipment, and the piping material. The Device may capture photographs of the set up (alignment and cleanliness) as well as the completed fusion bead. These records may be downloaded from the device and stored.
Note 1: The Device cannot show all aspects of the heat butt fusion conditions (such as wind, cold weather, blowing dust and sand, etc.) and does not preclude periodic joint testing as described in the applicable fusion standard or procedure.
SCOPE
1.1 This practice specifies the data recording information that is recorded, when data recording equipment is used, on heat butt fusion joints in a plastic piping system in order to compare the procedure used in making the joint to the heat butt fusion joining procedure specified. This practice is suitable for use with all heat butt fusion joining procedures such as Practice F2620, Specification F3372, Specification F2945 international standards or other qualified procedures. This practice primarily applies to hydraulically operated heat butt fusion machines and can be utilized for documenting heat butt fusion joints completed with manually-operated fusion machines.  
1.2 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title means only that the document has been approved through the ASTM consensus process.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Installation of Aluminum and Stainless Steel Jacketing over Thermal Insulation on Pipe and Rigid Tubing

SIGNIFICANCE AND USE
5.1 This practice applies to materials manufactured in accordance with Specification C1729 (aluminum jacketing) or Specification C1767 (stainless steel jacketing). This standard is intended to provide a basic practice for installing these types of materials. Refer to Specifications C1729 and C1767 for information on the differences between aluminum and stainless steel jacketing and where each is considered for use.  
5.2 This practice is not intended to cover all aspects associated with installation for all applications, including factory and field fabricated pipe fitting covers.
Note 1: Consult the National Commercial & Industrial Insulation Standards (MICA), Guide C1696, the product manufacturer, and/or project specifications for additional recommendations.  
5.3 Metal jacketing is typically used on insulated piping located outdoors, including, but not limited to, process areas and rooftops. Metal jacketing is used indoors where greater resistance to physical damage is required, for appearance, for improved fire performance, or as otherwise preferred. Metal jacketing used outdoors serves the same functions as indoors and also protects the insulation system from weather.  
5.4 Metal jacketing is used over all types of pipe insulation materials.
SCOPE
1.1 This practice covers recommended installation techniques for aluminum and stainless steel jacketing for thermal and acoustic pipe insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. This practice applies to materials manufactured in accordance with Specification C1729 (aluminum jacketing) or Specification C1767 (stainless steel jacketing). It does not address insulation jacketing made from other materials such as mastics, fiber-reinforced plastic, laminate jacketing, PVC, or rubberized or modified asphalt jacketing, nor does it cover the details of thermal or acoustical insulation systems.  
1.2 The purpose of this practice is to optimize the performance and longevity of installed metal jacketing and to minimize water intrusion through the metal jacketing system. This document is limited to installation procedures for metal jacketing over pipe insulation up to a pipe size of 48 in. NPS and does not encompass system design. This practice does not cover the installation of metal jacketing on rectangular ducts or around valves and gauges. It excludes the installation of spiral jacketing on cylindrical insulated ducts but is applicable to metal jacketing on cylindrical insulated ducts installed similarly to pipe insulation jacketing. Guide C1423 provides guidance in selecting jacketing materials and their safe use.  
1.3 For the purposes of this practice, it is assumed that the aluminum or stainless steel jacketing is of the correct size necessary to cover the thermal insulation system on the pipe or rigid tubing while achieving the longitudinal overlaps specified in 8.2.2 and 8.3.2. The size of the aluminum or stainless steel jacket necessary to achieve this specified longitudinal overlap closure is a complex topic for which the detailed requirements are outside the scope of this practice. Achieving this fit is very important to the performance of the total insulation system. See Appendix X1 for general information and recommendations regarding this closure of aluminum and stainless steel jacketing installed over thermal pipe and rigid tubing insulation.  
1.4 The intrusion of water or water vapor into an insulation system will, in some cases, cause undesirable results such as corrosion under insulation, loss of insulating ability, and physical damage to the insulation system. Minimizing the movement of water through the metal jacketing system is only one of the important factors in helping maintain good long-term performance of the total insulation system. There are many other important factors including proper performance and installation of the insulation, vapor retarder, and ...

Standard Specification for Threaded Couplings, Steel, Black or Zinc-Coated (Galvanized) Welded or Seamless, for Use in Steel Pipe Joints

ABSTRACT
This guide covers standard specification for black or galvanized welded or seamless threaded steel couplings for use with steel pipe joints in NPS 1/8 to NPS 20 [DN 6 to DN 500] inclusive. The steel for both welded and seamless couplings shall be made by one or more of the following processes: open-hearth, electric-furnace, or basic-oxygen. Welded couplings NPS 3½ [DN 90] and under may be butt-welded. Welded couplings over NPS 3½ [DN 90] shall be electric-welded. The steel shall conform to the required chemical composition for phosphorus and sulfur.
SCOPE
1.1 This specification covers black or galvanized welded or seamless threaded steel couplings for use with steel pipe in NPS 1/8 to NPS 20 [DN 6 to DN 500] inclusive (Note 1). Couplings ordered under this specification are intended for the uses outlined in the pipe specifications referencing this specification.  
Note 1: The dimensionless designator NPS (nominal pipe size) and DN [diameter nominal] has been substituted in this standard for such traditional terms as nominal diameter, size, and nominal size.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Contact Molded “Fiberglass” (Glass-Fiber-Reinforced Thermosetting Resin) Flanges

ABSTRACT
This specification covers the requirements for materials, workmanship, performance, and dimensions of circular contact-molded "fiberglass" (glass fiber reinforced thermosetting resin) flanges for use in pipe systems and tank nozzles. This specification does not address flange design or gasket selection. Flanges may be produced as integral flanges (Type A) or flange-on-pipe (Type B). They may be made of either epoxy resin (Grade 1), polyester resin (Grade 2), phenolic resin (Grade 3), vinylester resin (Grade 4), or furan resin (Grade 5). Flanges are also grouped into classes according to pressure and thrust capability as Class I (hoop and axial pressure) and Class II (hoop pressure only). Specimens shall undergo tests for which performance requirements must be met for sealing, short-term rupture strength, and maximum bolt torque.
SCOPE
1.1 This specification covers circular contact-molded fiberglass reinforced-thermosetting-resin flanges for use in pipe systems and tank nozzles. Included are requirements for materials, workmanship, performance, and dimensions.  
1.2 Flanges (see Fig. 1) may be produced as integral flanges, Type A, or flange-on-pipe, Type B.
