notes |
SSAW steel pipe's main characteristics are as follows:First,SSAW steel pipe is produced by dual side submerged arc welded process,it is not only has the high deposition rate,but also equiped with the ability of welding penetration.Second,because the electric arc and the welding area are well protected and the welding seam is of high quality,strong dense,smooth apperence,it can meet any requirement of the performance.It is weldly used in many common fluid engineering such as petroleum,coal gas,natural gas,water pipeline,and heating power. |

notes |
Hot-rolled seamless steel tubes with hollow cross-section, and most of them were used for transporting fluids. Compared with the steel pipes and the solid round bars, the steel pipes' weight are lighter at the same of strength and bending. It is an economic cross-section steel, and was widely used in manufacturing of structural parts and mechanical parts, such as drill pipe, automotive drive shaft bicycle rack, and steel scaffolding in construction, fluid transmission, the oil and natural gas's transportation and exploitation, boilers, et | |
