1、Designation: F 1865 02a (Reapproved 2009)An American National StandardStandard Specification forMechanical Cold Expansion Insert Fitting With CompressionSleeve for Cross-linked Polyethylene (PEX) Tubing1This standard is issued under the fixed designation F 1865; the number immediately following the

2、designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers

3、mechanical cold expansioninsert fittings with compression sleeve suitable for use withcross-linked polyethylene PEX plastic tubing in38 ,12 ,58 ,34, and 1in. and larger nominal diameters that meet the require-ments of Specifications F 876 and F 877. These fittings areintended for use in 100 psi (689

4、.5 kPa) cold and hot waterdistributions systems operating at temperatures up to andincluding 180 F (82C). Included are the requirements formaterials, workmanship, dimensions, and markings to be usedon the fittings and compression sleeves1.2 The values stated in inch-pound units are to be regardedas

5、standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of thi

6、s standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Measurements

19、 shall be madein accordance with Test Method D 2122. Determine the diam-eters by making measurements at four points spaced approxi-mately 45 apart around the circumference. Inspection andgauging of solder joint ends shall be in accordance with ANSIB 16.18, ANSI B16.22, or MSS SP-104. Inspection and

20、gaug-ing of taper pipe threads shall be in accordance with ANSI/ASME G1.20.1. All fittings that will be subjected to secondaryprocesses of mechanical marking that affect their dimensionaltolerances shall be tested in their final marked configuration.7.

The fittingwalls shall be free of cracks, holes, blisters, voids, foreigninclusions, or other defects that are visible to the unmagnifiedeye and that may affect the wall integrity.9. Assembly9.1 JointsMechanical Cold Expansion Insert Fittings withCompression Sleeve

24、shall be joined to the PEX tubing bydrawing a compression sleeve over the PEX tubing that hasbeen cold expanded and into which the fitting has beeninserted. This action forces the tubing into annular spacesformed by ribs on the fitting. Fittings and compression sleevesshall meet the dimensional tole

25、rances of this Specification.PEX tubing shall meet the requirements of Specification F 876or F 877.9.1.1 Solder Joints Soldering of fittings joints shall becompleted prior to installation of the PEX tubing. Excessiveheat from the soldering operation will damage the PEX tubing.9.2 Assembly ProcedureT

26、o affix the mechanical coldexpansion insert fitting with compression sleeve to the PEXtubing, the procedure shall be as follows: Cut the tubing squareusing a cutter designed for plastic tubing. Inspect the end forburrs or foreign debris. Slide the compression sleeve onto thetubing at least 1 in. (25

27、 mm) beyond the end of the tube. Insertthe properly sized expansion tool (see Note 1) fully into thetubing until the end of the tube meets the stop on the tool.Expand the tubing to the fullest reach of the tool. The fullestreach of the tool shall not expand the inside diameter of thetubing more than

28、 0.20 in. (5.0 mm) for sizes up to58 in.nominal and 0.24 in. (6.0 mm) for larger sizes up to 1 in. Insertthe fitting into the expanded tube. Place the joining tool ontothe fitting assembly in accordance with the tool manufacturersinstructions (see Note 1). Operate the joining tool to slide thecompre

29、ssion sleeve over the tubing and until it reaches the stopon the fitting. Remove the joining tool. Compression sleevesthat are damaged in any way shall not be re-used.NOTE 1Tool manufacturers provide a variety of expansion tools andjoining tools with adapters for use on the various fittings configur

30、ationsand sizes. These tools may utilize mechanical, electrical, hydraulic, orpneumatic devices to actuate their mechanisms. One inch sizes may notrequire expansion.10.
