Manufacturing process of forged steel pipe

The manufacturing process of forged steel pipe is to process raw steel into steel pipes of various lengths and diameters. Steel pipes play an important role in underground water and natural gas transmission, winding protection and production of automobiles, bicycles, pipelines and heating systems, street lamps and refrigeration equipment. It is generally believed that cast iron and forged iron are interchangeable terms of early iron, but there are huge differences between them. Wrought iron refers to iron processed with tools after heating. Cast iron is to pour iron into the mold and solidify it after melting.

Difference between forged pipe and cast iron pipe

Forged pipes are pipes made of steel and welded on welded or stretched seamless pipes or pipes. It is used for high-pressure applications and decorative work. Usually welded to elbows, etc.
The cast pipe is to pour iron or steel into the mold (which may break during centrifugal casting), and the mold shape will become hard. The casting is heavy, the wall thickness is weak, the cost is low, and it is not suitable for higher pressure. Cast fittings can be sealed by threads or other means.

Types of forged steel pipes

Forged seamless steel pipe

Seamless forged steel pipe was originally a piece of heated solid steel. The material is forced into the shape of hollow pipe, and then the pipe is processed into appropriate size.

Welded steel pipe

The manufacturing of welded forged steel pipe includes moving the steel strip through the roll to make the material into pipe. These strips are then welded into tubes by welding equipment.

How to manufacture forged steel pipe?

Welded and seamless forged iron pipes are usually passed through straighteners. Threads machined to the ends of smaller diameter pipes allow them to be connected together. In addition, there are various protective coatings on the steel surface. It is such as oil, paint, zinc or other types of materials, which can prevent rust according to the purpose of the pipeline.
