Bent wire refers to the outer wire joint that is bent. Bending wires can be bent into different angles and shapes according to different pipeline systems and construction needs; At the same time, different bent wires also play different roles in the pipeline system, such as changing the direction of the pipeline, buffering pipeline pressure, etc., especially in some complex construction environments where bent wires are commonly used.

Seamless elbow: An elbow is a type of pipe fitting used at the bend of a pipeline. The proportion of all fittings used in the pipeline system is about 80%. Usually, different forming processes are selected for elbows of different materials or wall thicknesses. At present, the commonly used seamless elbow forming processes in manufacturing plants include hot pressing, stamping, extrusion, etc.
