Standard Specification for Metal Insert Fittings for Polyethylene/Aluminum/Polyethylene and Crosslinked Polyethylene/Aluminum/Crosslinked Polyethylene Composite Pressure Pipe

ABSTRACT
This specification covers metal insert fittings with split ring and compression nut (compression joint) and metal insert fittings with copper crimp rings (crimp joint) for four sizes of composite pressure pipe. These fittings are intended for use in cold- and hot-water distribution systems operating at a certain temperature range. These fittings are intended for use in potable water distribution systems for residential and commercial applications, water service, underground irrigation systems, and radient panel heating systems, baseboard, snow- and ice-melt systems, and gases that are compatible with the composite pipe and fittings. The fittings are classified into two classes with split ring and compression nut and fittings with a copper crimp ring, suitable for use with four sizes of PEX/AL/PEX or PE/AL/PE pipe. The fittings shall be made from one of the following metals: wrought copper, cast copper alloy, machined brass, and forged brass. Different tests shall be conducted in order to determine the following properties: hydrostatic burst, hydrostatic sustained pressure strength, thermocycling, and excessive temperature and pressure capability. The sealing surfaces of the insert shall be smooth and free of foreign material. The fitting walls shall be free of cracks, holes, blisters, voids, foreign inclusions or other defects that are visible to the naked eye and that affect the wall integrity.
SCOPE
1.1 This specification covers metal insert fittings with split ring and compression nut (compression joint) and metal insert fittings with copper crimp rings (crimp joint) for four sizes of composite pressure pipe. These fittings are intended for use in 125 psi (690 kPa) cold- and hot-water distribution systems operating at temperatures up to and including 180 °F (82 °C). (When used in polyethylene/aluminum/polyethylene systems the maximum operating temperature is limited by the pipe to 140 °F (60 °C) and where applicable 180 °F (82 °C)). Included are the requirements for materials, workmanship, burst pressure, sustained pressure, excessive temperature and pressure, temperature cycling tests, and markings to be used on the fittings and rings. The fittings covered by this specification are intended for use in potable water distribution systems for residential and commercial applications, water service, underground irrigation systems, and radient panel heating systems, baseboard, snow- and ice-melt systems, and gases that are compatible with the composite pipe and fittings.  
1.2 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.
Note 1: The tables show the “nominal size” in millimetres with the inch size in parentheses. This exception is made to harmonize the “nominal size” with the two pipe standards, Specifications F1281 and F1282.  
1.3 The following precautionary caveat pertains only to the test method portion, Section 9, of 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.  
1.4 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.

6. Performance Requirements
6.1 General—All performance tests shall be performed on assemblies of fittings and PEX/AL/PEX pipe. Fittings, split rings and
crimp rings shall meet the material and dimensional requirements of this standard. PEX/AL/PEX pipe shall meet the requirements
of Specification F1281. Assembly of test specimens shall be in accordance with either 8.1 or 8.2, as applicable. Each assembly shall
contain at least one joint. Use separate sets of assemblies for each performance test requirement.
6.2 Hydrostatic Burst—Assemblies shall meet the minimum hydrostatic burst requirements shown in Table 1 when tested in
accordance with 9.5.
6.3 Hydrostatic Sustained Pressure Strength—Pipe and fitting assemblies shall not separate or leak when tested in accordance
with 9.6.
6.4 Thermocycling—Assemblies shall not leak or separate when thermocycled 1000 cycles between the temperatures of 60°F
(16°C) and 180°F (82°C)60 °F (16 °C) and 180 °F (82 °C) in accordance with 9.7.
6.5 Excessive Temperature-Pressure Capability—Assemblies shall not leak or separate when tested in accordance with 9.8.
7. Dimensions
7.1 Dimensions and Tolerances—The dimensions and tolerances of fittings, split rings and crimp rings shall be as shown in
Tables 2-4 when measured in accordance with 9.4.
7.1.1 Alignment—The maximum angular variation of any opening shall not exceed 1° off the true centerline axis.
7.1.2 Fittings with Solder Joint Ends—Solder joint ends shall be in accordance with ANSI B16.22, ANSI B16.18, or MSS
SP-104.
7.1.3 Tapered Threaded Ends—Fitting threads shall be right-hand conforming to ANSI/ASME B1.20.1. They shall be taper
threads (NPT).
8. Workmanship, Finish, and Appearance
8.1 The sealing surfaces of the insert shall be smooth and free of foreign material. The fitting walls shall be free of cracks, holes,
blisters, voids, foreign inclusions or other defects that are visible to the naked eye and that affect the wall integrity.
8.1.1 Assembly—Insert fittings shall be joined to PE/AL/PE or PEX/AL/PEX pipe by the use of either a crimp joint or a
compression joint.
8.1.2 Crimp Joints—Crimp insert fittings shall be joined to PE/AL/PE or PEX/AL/PEX pipe by the compression of a copper
crimp ring around the outer circumference of the pipe forcing the pipe material into annular spaces formed by ribs on the fitting.
The dimensions and out-of-roundness of the crimp ring after it has been crimped shall be in accordance with Table 5.
8.1.2.1 Crimping Procedure—To affix the insert fitting to the pipe with the crimp ring, the crimping procedure shall be as
follows: slide the crimp ring onto the pipe, insert the ribbed end of the fitting into the end of the pipe until the pipe contacts the
1 1
shoulder of the fitting or pipe stop. The crimp ring shall then be positioned on the pipe so the edge of the crimp ring is ⁄8 to ⁄4
in. (3.2 to 6.4 mm) from the end of the pipe. The jaws of the crimping tool shall be centered over the crimp ring and the tool shall
be held so that the crimping jaws are perpendicular to the axis of the barb. The jaws of the crimping tool shall be closed around
the crimp ring, compressing the crimp ring onto the pipe. The crimp ring shall not be crimped more than once. Each crimp shall
be checked to determine conformance to the after crimped dimensional requirements of Table 5.
8.2 Compression Joints—Compression insert fittings shall be joined to PE/AL/PE or PEX/AL/PEX pipe through the
compression of a split ring, by an compression nut, around the outer circumference of the pipe forcing the pipe material into the
annular space formed by ribs on the fitting.
8.2.1 Compression Jointing Procedure—To affix the insert fitting to the pipe with the split ring, and compression nut the
procedure shall be as follows: slide the compression nut and split ring onto the pipe, insert the ribbed end of the fitting into the
end of the pipe until the pipe contacts the shoulder of the fitting or pipe stop. Position and compress the split ring by tightening
the compression nut onto the insert fitting.
