What is Mandrel Mill Pipe Manufacturing Process?

It involves the use of a mandrel, which is a cylindrical tool inserted into a hollow billet or mother tube. The mandrel supports the inner walls of the tube while it is rolled and stretched over a mandrel mill to reduce its diameter and increase its length. This process ensures the uniformity & high-quality finish of the tubes.

What are The Different Stages Involved in the Manufacturing of Seamless Pipes?

Manufacturing seamless pipes involves several stages to ensure the production of high-quality pipes. The process typically begins with preparing the mother tubes, followed by the piercing or extrusion to form the initial hollow tube. Then, the tube is elongated and reduced in diameter through mandrel or plug milling processes.
