SSAW (Spirally Submerged Arc Welding) pipes are made from hot-rolled steel coils. These pipes mainly used in petroleum and natural gas industry to transport flammable and non-flammable liquid and steel construction. With 13-year experience in manufacturing pipes, customers can always find what they need.
