Carbon Steel/Stainless Steel/Alloy Steel A335 P91 ANSI B16.9 Pipe Fittings Elbow
Elbow is a kind of pipe fittings commonly used in pipeline installation to provide flexibility to change the pipe direetion.
It connects two pipes of the same nominal diameter or different diameter, so that the pipe bends at a certain angle,usually a 90 or 45 degrees.The ends may be machined for butt welding threaded or socketed. When the ends differ in size,it is known as a reducer elbow.
According to bend degree, there are 90 degree elbow and 45 degree elbow; according to length, there are long radius elbow and short radius elbow.
Due to the elbow with good comprehensive performance, so it is widely used in chemical industry, building, water supply, water drainage, oil, light and heavy industry, freezing, sanitary, plumbing, fire protection, electric power, aerospace, shipbuilding and other infrastructure projects.
