ASTM Forged Butt Welding Elbow

Elbow is a kind of pipe fitting used in pipe bends. Among all the pipe fittings used in the pipeline system, the proportion is the largest, about 80%. Usually, different forming processes are selected for elbows of different materials or wall thicknesses. Commonly used seamless elbow forming processes in manufacturers include hot pushing, stamping, extrusion, etc.

hot push forming

We have focused on fitting machines more than 39years. Our company produce and export all kinds of carbon steel pipe fittings, Our city Cang Zhou city is the hometown of carbon steel pipe fittings.

A 90 degree elbow is a pipe fitting which you can used to change the flow direction in a 90 degree.It is also called“90 bend”or “quarter bend”. As a joint between two pipes,the 90 degree elbows are also used as a railing ends or corners on a level installation.

For the butt welding steel elbow,it is made from a piece of seamless pipe commonly.Bending the two ends of pipe to a angle of 90 degree,it is a 90 degree seamless elbow.There also some 90 degree elbows are made from the ERW pipes or the steel plates,then they are welded elbow.The 90 degree elbows are manufactured as SR (Short Radius) elbows and LR (Long Radius) elbows or other radius elbows.
