47、E USED FOR DEVELOPMENT OF SPECIFICATION F 682X1.1 This specification has been developed to provide twotypes of couplings. Type I is for use on all schedules of pipe inwhich the pipe wall thickness does not exceed the wallthickness of standard weight pipe. Type II is for use on allschedules of pipe i
48、n which the pipe wall thickness does notexceed the wall thickness of extra strong pipe. Note 3 providesan option that allows the use of Type II couplings in place ofType I couplings, if desired.X1.2 The design criteria for the couplings is based on CFRTitle 46, Subpart 56.70-15(d)3 and 4 as follows:
49、X1.2.1 For couplings through 3-in. IPS, the clearance be-tween the system pipe outside diameter and the sleeve couplinginside diameter has been held to a maximum of 0.080 in. whenconsidering tolerances to allow these couplings to be used inClass I piping through 3 in. when not subjected to fullradiography as allowed by CFR Title 46. The inside diameterof the coupling is therefore equal to the minimum outsidediameter of the pipe to be joined +0.080 in. with a tol
