At China Steel Pipe Group, our ERW steel pipes are engineered to form a critical part of building fire safety systems. Constructed from high-strength, low-alloy steels such as Q235B and Q355, these pipes are specially designed to ensure the reliable operation and safety of fire fighting equipment.
Our ERW steel pipes are used to connect various components within fire suppression systems. The pipes are crucial for conveying fire suppression agents such as water and gas, ensuring rapid response during emergencies. To meet the rigorous demands of fire safety, our pipes adhere to stringent quality and safety standards. Regular inspections and maintenance are facilitated by the pipe's design and material properties, reducing the likelihood of failures and ensuring that systems remain operational when needed most.

Our ERW round steel pipes are longitudinally welded pipes that are manufactured by forming steel strip into hollow shape, and then welded along the length of the steel pipe.
Spiral welded steel pipes are produced by spirally winding a steel strip at a predetermined angle, forming a tube that is welded along the seam.
Seamless steel pipes are manufactured by thrusting a piercing mandrel through a steel billet to form a hole, then processed by a rolling mill to a specified diameter and wall thickness.
