Butt Welding Pipe Fitting Manufacturers in China
ASME B16.9 is the standard for factory-made wrought butt-welding pipe fittings in sizes 1/2" through 48". Generally speaking, butt-welding pipe fittings are fabricated pieces of pipe that are used either to make changes of direction(elbow&return), close the pipeline end(end caps), branch from the main pipe(tee), or make a reduction in line size(reducer). They can be made from seamless pipes, welded pipes or plates.
