STRUCTURAL MEMBER FOR SLIP-ON TYPE WELD PIPE-FITTING

摘要

PROBLEM TO BE SOLVED: To obtain a sufficient weld heat input even if the weld heat input is lowered by dispersion. SOLUTION: The structural member for a slip-on type weld pipe-fitting includes an insertion hole in which a pipe is inserted and fillet welding is performed. On the periphery in the side of the inside diameter of the insertion opening, a minute projection to be melted by a weld heat input in fillet welding is provided. COPYRIGHT: (C)2010,JPO&INPIT
