31、ssembly9.1 Crimp JointsInsert fittings shall be joined to PEXtubing by the compression of a copper crimp ring around theouter circumference of the tubing, forcing the tubing materialinto annular spaces formed by ribs on the fitting. Insert fittingsand crimp rings shall meet the dimensional and mater

32、ialrequirements of this standard. PEX tubing shall meet therequirements of Specifications F 876 or F 877. The dimensionsand out-of-roundness of the crimp ring, after it has beencrimped, shall be in accordance with Table 1.9.1.1 Crimping ProcedureThe crimping procedure shallbe as follows: slide the c

33、rimp ring onto the tubing, insert theribbed end of the fitting into the end of the tubing until thetubing contacts the shoulder of the fitting or tube stop. Thecrimp ring shall then be positioned on the tubing so the edge ofthe crimp ring is18 to14 in. (3.2 to 6.4 mm) from the end ofthe tube. The ja

34、ws of the crimping tool shall be centered overthe crimp ring and the tool shall be held so that the crimpingjaws are approximately perpendicular to the axis of the barb.The jaws of the crimping tool shall be closed around the crimpring, compressing the crimp ring onto the tubing. The crimpF1807082ri

35、ng shall not be crimped more than once. Each crimp shall bechecked to determine conformance to the after-crimped dimen-sional requirements of Table 1 .10.
