Buttweld fittings constructed of stainless steel 304L, the low-carbon version of stainless steel 304, are one form of pipe fitting. These fittings are intended for butt welding, which involves beveling the fitting ends and welding them to the pipes, to join and link pipes in a piping system.
Buttweld fittings made of stainless steel 304L are produced in line with a number of international standards, including ANSI/ASME, DIN, EN, and others. To fit different pipework, they come in a variety of sizes, schedules (wall thickness), and types, including elbows, tees, reducers, and caps.
