Spiral steel pipe is an important steel pipe in the project construction. It is formed by spiral submerged arc welding technology. The process is formed using narrower plates or hot rolled coils, which lowers their production costs significantly. The welding line is shaped like a helix. The spiral welding process permits the production of large-diameter pipes suitable for transporting large volumes of oil and gas. BESTAR Steel Co., Ltd is a China-leading product service provider and exporter of steel pipe. It passed the SGS Certification of China Supplier System, ISO9001 Quality Management System Certification, ISO 14001 Environment Management System Certification, ISO45001 Occupational Health & Safety Management System Certification, and so on.
