Product Description

Structural steel pipes are divided into carbon structural steel pipes and low-alloy high-strength structural steel pipes.Carbon structural steel pipes are mainly used in plants, bridges, ships and other buildings and pipes for general transportation of fluids.This kind of steel is generally used directly without heat treatment.Low alloy high strength structural steel pipes are widely used in ships, bridges, boilers, vehicles and important buildings due to their high strength and comprehensive mechanical properties.
