Weldable pipe fitting
摘要:
A male fitting (15) comprising a fitting body (16) of a first material elongated along a longitudinal axis and having an outer surface (23, 27) and an inner surface (20) defining a through-passage (28), the outer surface having a first portion (23) and a shoulder (18) extending radially from the first portion, the shoulder being integral to the fitting body and formed substantially of the first material, the first portion of the outer surface adapted to engage a corresponding aperture (39) in a mating member (35), and the integral shoulder adapted to be heated into provide an autogenous weld (45) between the fitting body and the mating member.
