Q345B SSAW Pipe for Piling Pipe and Piling Tube

Q235B spiral steel pipe is a common material in spiral tubes. It is a spiral seam steel pipe that is based on strip coiled sheet and is extruded at room temperature and welded by an automatic double-wire double-sided submerged arc welding process.

Common standards of spiral steel pipes are generally divided into: SY/T5037-2000 (partial standard, also called spiral seam submerged arc welded steel pipe for ordinary fluid conveying pipeline) and GB/T9711.1-1997 (national standard, also called oil and gas industrial conveying steel pipe) Technical conditions for delivery Part I: Class A steel pipe (rigid requirements are GB/T9711.2 Class B steel pipe)), API-5L (American Petroleum Institute, also called pipeline steel pipe; which is divided into two grades of PSL1 and PSL2), and SY/T5040-92 (spiral submerged arc welded steel pipe for piles).
