ADAPTOR
FOR WELDING TUBES OF ALUMINUM ALLOYS WITH TUBES OF STAINLESS STEEL
 FIELD:
jointing by welding tubes of different metals, particularly tubular adaptors
aluminum alloy - stainless steel.
SUBSTANCE: intermediate layer of adaptor is made
in the form of sleeve of titanium alloy. One end of said sleeve is lap jointed
by diffusion welding with sleeve of stainless steel; its other end is lap
jointed with sleeve of aluminum alloy by welding-soldering process. Zones of
diffusion welding and welding-soldering joints are mutually spaced by distance
no more than 10 mm. Joint of sleeve of titanium alloy with sleeve of stainless
steel may be made as male part and joint of titanium alloy sleeve with aluminum
alloy sleeve may be made as female part. Length of lap joint of aluminum alloy
sleeve with titanium alloy sleeve is no less than three thickness values of
walls of sleeve of aluminum alloy. Length of lap joint of titanium alloy sleeve
with stainless steel sleeve is no less than 15 mm.
EFFECT: improved design of adaptor providing its
increased strength. 4 cl, 1 dwg, 1 ex
