Q235B Q345B Welded Steel Pipe

Professional Welded Pipe Supplier

The 20th century has seen advances in steel pipes, production economics and product quality. Of note are the machines and techniques used to cold-form flexible steel pipe from steel sheet coils using automated spiral welds. Great strides have also been made in quality control, testing, joints and protective coatings.
Welded steel pipe is available in a wide range of sizes and steel properties. The requirements for buried pipes are high strength, ease of installation, high flow rates, resistance to leakage, long service life, reliability and versatility as well as economy. The properties of steel are well suited to meet these seven requirements for buried piping.
