Manufacturing Process for Large OD Seamless Steel Pipe

1. The production process of large OD seamless steel pipes involves several steps. First, the raw material is selected, which is mostly hot-rolled steel. The hot-rolled steel is then heated to a temperature above its recrystallization temperature. The heated steel is then rolled into a long pipe-shaped structure called a billet.

2. The billet is then passed through a piercing machine where it is punched to form a hollow cylinder. The cylinder is then passed through a reheating furnace to soften it. After reheating, the cylinder is passed through a sizing machine where it is given its final shape and size.

3. The final product is then tested for its various mechanical properties such as tensile strength, yield strength, elongation, and hardness. The large OD seamless steel pipes are then coated with a protective layer to prevent corrosion and abrasion.
