Butt welding elbow pipe fitting is a long steel strip with hollow section and no joint around.Steel pipe with hollow section, many used for transporting fluid pipeline, such as transporting oil, natural gas, gas, water and some solid material pipeline.Compared with solid steel such as round steel, steel pipe is lighter in bending and torsional strength. It is a kind of economic section steel, widely used in the production of structural parts and mechanical parts butt welding elbow pipe, such as oil drill pipe, car drive shaft, bicycle frame and steel scaffolding used in construction.

As the circumference is flat, the larger the circle area, the more fluid can be transported with the round pipe.In addition, the annular section receives the internal or external radial pressure, the force is more uniform, so the vast majority of steel tubes are round.The output flow of seamless butt welding elbow fittings is large, suitable for all walks of life, and it is convenient to connect with other steel pipes.
 

Butt welding elbow fittings not only save space, reduce the weight, more importantly, to ensure that the joint part will not leak, with good sealing performance.The size of the compact flange is reduced by reducing the diameter of the seal, which will reduce the section of the sealing face.Secondly, flange gaskets have been replaced by sealing rings to ensure that the sealing face matches.
