Cold-expansion fittings and compression-sleeves shal
47、l meetF2080 163the dimensional and material requirements of this specification. PEX pipe Pipe shall meet the requirements of Specification F876.in 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 a six-section radial expanding
48、 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
49、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 inside the pipe. Expand the pipe for approximately 3 s, and removethe tool. Rotate the tool approximately 30, insert the expander-tool into the pipe and repeat the expansion process. Thecold-expansion fitting shall be inserted within 30 s of the second expansion. The fitting is properly inserted when the PEX pipeis pushed up agai
