Elbow Direction Angle

There are three common angles of the elbow to use in the piping system, 45 degree, 90 degree and 180 degree, these angle types turn fluid in different directions, including right angles and return angles, there are also other angles to use, like 60 degree and 180 degree.

45 Degree Elbow

45 degree elbow changes the flow direction to 45 degrees, it includes long radius 45 degree elbow and short radius 45 degree elbow.

90 Degree Elbow

90 degree elbow changes the flow direction to 90 degrees, it also has long radius and short radius types, 90 degree elbow is the most used elbow..

180 Degree Elbow

180 degree elbow changes the flow direction to 180 degrees.

Elbow Connection Style

According to connection style, the elbow can be classified butt weld elbow, socket welded elbow and threaded elbow, butt weld elbow is a commonly used type.

Butt Weld Elbow

Butt weld refers to connecting pipes and fittings ends by butt welding method, it has ends beveled to make it easy to weld, beveled ends should be conformed to the requirement of ASME B16.25, and the plain end is offered upon request, BW elbow dimensions can be from 1/2" to 72", BW weld elbow can be made of both seamless and welded pipe by the process of hot forming that includes bending and forming to shape.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow, is lower cost elbow, thin wall sizes can be allowed.
