Product Details

6 inch Steel Spiral Pipe From the safety evaluation point of view of the whole pipeline, the current standard is more and more inclined to avoid repairing and cutting as much as possible, because most experience has proved that the quality and performance of repaired welding joints are often inferior to that of the welding joints with defects.Because of the complexity of the methods for evaluating the impact of defect size on safety, the old acceptance criteria are still used in the standards despite such experience.

(1) the combination process of using cellulose electrode as the base and flux cored wire for self-shielded welding to fill the cover of X70 pipeline is a relatively mature process, which has the characteristics of high qualification rate, high efficiency and good applicability and has been accepted by most pipeline construction teams.

(2) the guarantee of the welding quality of pipeline construction site mainly depends on the control of the quality of materials and equipment, the qualification of construction personnel and the on-site quality management.

(3) the defects that need to be repaired or cut should be carefully treated, and the on-site pseudo-work should be carried out.
