This process enhances the structural integrity and uniformity of the pipe.

a) Hot Rolling Process

During hot rolling, the billet is first heated above its recrystallization temperature to make it more malleable. It is then passed through multiple sets of rolls that gradually reduce its diameter while elongating its length.

The intense heat and pressure mold the steel into a cylindrical shape with consistent thickness. This process also refines the microstructure, eliminates internal defects, and improves overall mechanical properties.

b) Heat Treatment Stages

After hot rolling, heat treatment stages are employed to further enhance the strength and durability of the steel pipe. These include processes like normalizing, annealing, quenching, or tempering depending on specific requirements. Heat treatment helps relieve residual stresses induced during manufacturing and achieves desired hardness levels for optimal performance in different environments.

Welded Method

As an alternative to seamless pipes, welded pipes can also be manufactured for a 400 mm OD steel pipe using various techniques such as electric resistance welding (ERW) or submerged arc welding (SAW). Welded pipes are formed by joining two edges of a flat strip or plate together using heat and pressure.

a) Electric Resistance Welding (ERW)

In this method, an electric current passes through the edges of two strips placed in close proximity. The resulting heat melts the material at those edges which are then pressed together to create a solid joint. ERW ensures strong bonds between metal surfaces but may introduce slight dimensional variations compared to seamless pipes.

b) Submerged Arc Welding (SAW)

Submerged arc welding involves creating an electric arc between the steel strip and a welding wire. The arc is shielded by granular flux, which provides protection against oxidation and impurities.

This method allows for high-quality welds with excellent mechanical properties. The manufacturing process for a 400 mm OD steel pipe requires careful consideration of raw materials, such as the type and grade of steel used, as well as their chemical composition.
