Seamless elbows, like other pipe fittings, can experience various types of deformations during their manufacturing process or in service. Here are some common deformations of seamless elbows:1. **Bending Deformation**: Seamless elbows are typically subjected to bending to achieve the desired curvatu

Residual stresses in steel pipes can arise during the manufacturing process, particularly through processes like rolling, forging, welding, or cold drawing. These stresses are not intentionally introduced for structural purposes but are instead a byproduct of the manufacturing techniques. Here's how

**Cold Drawn Pipe:**- A cold drawn pipe is a hollow cylinder that is formed by extruding a metal rod through a die to create a hollow center and then drawing the rod through the die to reduce its diameter, resulting in a smooth finished surface.- The process of making cold drawn pipes typically invo

The seamless tube extrusion process is a manufacturing method used to produce seamless tubes and pipes with a continuous internal diameter and a smooth external surface. This process involves several steps:1. **Selection of Material**: The first step is to select the appropriate steel grade and diam
