Special application for round and hollow seamless steel pipe

Joints or not would be an important judgement for ERW and seamless steel pipe. For the latter, they are round and hollow which are manufactured by drawing solid billet through a piercing rod. And this production process would finally lead them for the special function during the engineering project.

High pressure situation would be their favorite challenge. And you will see them in Hydrocarbon Industries & Refineries, Oil & Gas Transportation and Air and Hydraulic cylinders, Oil & Gas Exploration & Drilling, Bearings, Boilers, Automobiles etc. Of course, high temperature is also the place to show their advantage, like boiler’s making.
