Assembly9.1 Joints:9.1.1 Cold-Expansion Join
47、tsFittings shall be joined to pipe by first expanding the end of the pipe with the expander tool,inserting the cold-expansion fitting into expanded pipe, then pulling the compression-sleeve over the pipe and the fitting,compressing the pipe between the compression-sleeve and the fitting. Cold-expans
48、ion fittings and compression-sleeves shall meetthe dimensional and material requirements of this specification. Pipe shall meet the requirements of Specification F876 or F3253in the case of PEX pipe or Specification F2769 in the case of PE-RT pipe.9.2 Expander Tool:9.2.1 The expander tool shall have
49、 a six-section radial expanding cylindrical-shaped head with unexpanded and maximumexpanded diameters as shown in Table 1.9.2.2 The expander tool shall be inspected according to manufacturers instructions.9.3 Procedure:9.3.1 Slide the compression-sleeve onto the pipe so that the inside-beveled end is facing toward the end of the pipe. Slide thecompression-sleeve far enough down the pipe so that it will not prevent expansion of the pipe. Insert the head of the expander-toolinto the pipe. The expander-tool segments shall be centered
