Standard Specification for Quick Disconnect Couplings (6 in. NPS and Smaller)

ABSTRACT
This specification covers the manufacturing data required to produce a variety of styles and sizes of quick disconnect couplings up to and including NPS 6 for marine use that ensure interchangeability and safety of operation. Quick disconnect couplings shall consist of the following types: Standard class and Class I. Adapters and couplers are to be produced as castings or forgings. Cam handles may be produced by casting, forging, or sintered metal processes. Maximum allowable working pressure (MAWP) for a Standard Class coupling shall be 25 % of its burst pressure. Maximum allowable working pressure for a Class I coupling shall be 20 % of its burst pressure. The following test shall be performed: pressure tests and production test.
SCOPE
1.1 This specification covers the manufacturing data required to produce a variety of styles and sizes of quick disconnect couplings up to and including NPS 6 for marine use that ensure interchangeability and safety of operation.  
1.2 In general, quick disconnect couplings are hose and pipe end fittings that permit quick mechanical attachment by means other than bolted or threaded fittings. The method of attachment is a male coupling half (adapter, tank unit) that fits into a female coupling half (coupler, hose unit) of the same size.  
1.2.1 By closing attached cam handles on cam and groove couplings, the coupling halves seal, permitting fluids to be transported under pressure through the quick disconnect coupling.  
1.2.2 By aligning the rollers on the hose unit coupler with the notches on the tank unit adapter on the dry disconnect coupling (DDC), push the coupler onto the adapter and rotate past 100°. This will lock the couplings together, create a seal and open the internal valves for full flow with low pressure drop. The dual poppet design shut-off mechanism seals liquids and gases behind the valve, eliminating fugitive emissions and the danger of a spill upon disconnection.  
1.3 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.  
1.4 The following safety hazards caveat pertains only to the test method described in this specification:  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.  
1.5 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 Circular Metallic Bellows Type Expansion Joints for Piping Applications

ABSTRACT
This specification establishes the minimum requirements for the mechanical design, manufacture, inspection, and testing of circular metallic bellows-type expansion joints used to absorb the dimensional changes resulting from piping thermal expansion or contraction, as well as the movement of terminal equipment and supporting structures. Materials used shall be free from defects that would adversely affect the performance of the expansion joint. All pressure retaining components shall be hydrostatically tested to meet the requirements prescribed.
SCOPE
1.1 This specification establishes the minimum requirements for the mechanical design, manufacture, inspection, and testing of circular metallic bellows-type expansion joints used to absorb the dimensional changes resulting from piping thermal expansion or contraction, as well as the movement of terminal equipment and supporting structures.  
1.2 Additional or better features, over and above the minimum requirements set by this specification, are not prohibited by this specification.  
1.3 The layout of many piping systems provides inherent flexibility through natural changes in direction so that any displacements produce primarily bending or torsional strains, within acceptable limits. Where the system lacks this inherent flexibility the designer should then consider adding flexibility through the use of metallic bellows-type expansion joints.  
1.4 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.  
1.5 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.

3.3 Expanded welded and silver brazed socket joints may be used where experience or test has demonstrated that the joint is safe and suitable for design and operating conditions, and where adequate provision is made to prevent separation of the joint.
SCOPE
1.1 This practice covers expanded welded and silver brazed socket joints for use on shipboard piping systems.  
1.2 Expanded welded and silver brazed socket joints are to be used to join two pipes or tubes having the same NPS (see Note 1) without using a fitting or butt weld.  
1.3 Brazed socket type joints are not intended for use on systems containing flammable or combustible fluids in areas where fire hazards exist or where the service temperature exceeds 425°F (205°C).  
1.4 Brazed joints depending solely upon a fillet weld rather than primarily upon brazing material between pipe/tube and socket are not covered by this practice.  
Note 1: The dimensionless designator nominal pipe size (NPS) has been substituted in this practice for such traditional terms as “nominal diameter,” “size,” “nominal size,” and “iron pipe size.”  
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.  
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 Specification for Performance of Gasketed Mechanical Couplings for Use in Piping Applications

ABSTRACT
This specification provides the performance characteristics and qualification tests required for gasket mechanical couplings (GMCs) including grooved-type mechanical couplings for grooved end pipe, mechanical restraint couplings for plain end pipe and mechanical compression couplings for plain end pipe. These couplings are for use at temperatures within the recommended temperature range of their respective gaskets. The GMCs are classified into two types: Type I which are the groove mechanical couplings and Type II which are plain end mechanical couplings. Also, they can be classified into various grades based on successful completion of testing. They can also be grouped into three classes in accordance to joint characteristics: Class 1 which is rigid and restrained, Class 2 which is flexible and restrained, and Class 3 which is flexible and unrestrained. The housings of grooved GMCs shall be made from either ductile iron, aluminum alloy, or iron-chromium-nickel alloy. Bolts of these couplings shall be made from carbon steel and corrosion resistant materials. As for plain end GMCs, their housings or center sleeves shall be made from either ductile iron or steel materials. Their bolts shall be constructed with carbon steel and corrosion resistant materials. Standard qualification tests for GMC shall consist of the following: performance test, specimen examination, pneumatic proof test, vacuum test, hydrostatic proof test, flexibility test, hydrostatic burst test, rigidity test, bending moment proof test, and bending moment ultimate test.
SCOPE
1.1 This specification provides the performance characteristics and qualification tests required for gasketed mechanical couplings including grooved-type mechanical couplings for grooved end pipe, mechanical restraint couplings for plain end pipe, and mechanical compression couplings for plain end pipe.

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.
