Product Introduction

The round steel pipe is also know as round steel tube, or circular hollow section. The round steel pipe can be seamless - SMLS pipe, longitudinal submerged arc welding - LSAW pipe, Electrical Resistance Weld - ERW pipe, Spiral Submerged Arc Welding - SSAW pipe. For the round steel pipe, we also provide concrete weight coating and anti-corrosion treatment, such as 3PE / 3LPE, FBE.

The main round steel pipe types we supply are structural steel pipe, line pipe, boiler pipe, pipe for conveyance of fluid, low temperature service pipe, gas cylinder pipe, fine grain structure pipe, pipe for pressure purposes, tubing and casing, etc.

The round steel pipe circular hollow section is used to transport fluid and powder solids, exchange heat energy, manufacture mechanical parts and containers. It is an economic steel. Making highway bridges with steel pipes can not only save steel and simplify construction, but also greatly reduce the area of protective coating and save investment and maintenance costs.
