Knowledge of seamless elbows

Seamless elbow is a kind of pipe connection, its role is to change the flow direction and flow direction of the pipeline. It is usually composed of elbow body, connecting pipe and reinforcement, and can be bent at different angles according to needs, common 90 degrees, 45 degrees, 30 degrees and so on. Here's what you need to know about seamless elbows.

1, seamless elbow material and manufacturing process

Seamless elbow is usually made of carbon steel, alloy steel, stainless steel and other materials, with high temperature resistance, corrosion resistance and other characteristics. The manufacturing process is generally carried out by hot extrusion, hot bending or cold extrusion.

1. Hot extrusion: the billet is heated to a certain temperature, and then the billet is extruded into the shape of the elbow through the mold. This manufacturing process is suitable for elbows with larger diameters and smaller angles.

2. Hot bending: Bend the heated pipe through the mold. This manufacturing process is suitable for large Angle elbows.

3. Cold extrusion: the billet is bent into the shape of a bend by special equipment. This manufacturing process is suitable for elbows with smaller diameters and smaller angles.
