3pe spiral steel pipe
The main development direction of spiral welded pipe is:
(1) production of large-diameter thick-walled pipes to improve pressure resistance;
(2) design and production of new structure of steel pipe, such as double spiral welded pipe, that is, the thickness of the wall is half of the strip welded into a double layer of pipe, not only the strength of the same thickness of the single layer of pipe is higher, and does not appear brittle damage;
(3) to develop new types of steel, improve the level of smelting technology, widely adopt the controlled rolling and post-rolling waste heat treatment process, in order to continuously improve the strength and toughness of the pipe body and welding performance;
(4) vigorously develop coated tubes, such as coating the inner wall with anticorrosive coating, can not only extend the service life, but also improve the smoothness of the inner wall, reduce fluid friction resistance, reduce wax deposition and dirt, reduce pigging times, reduce maintenance costs.
When welding fixture and other components, arc ignition and arc extinguishing on the base material are strictly prohibited.10. For double-sided welding, carbon arc air gouging or angular grinder shall be used for root cleaning on the back after unilateral welding to remove the locating weld metal welded on the root cleaning side.When the carbon arc air gouging is used, the grinding wheel shall be used to trim the grooves.11. When the local clearance of weld assembly exceeds 5mm, but the length is no longer than 15% of the weld length, surfacing treatment on both sides or one side of the groove is allowed, provided that the following provisions are met:A. it is strictly prohibited to fill the gap with metal materials;B. Apply grinding wheel dressing after surfacing;
The Process Flow
has more than ten years history company which located in Lecong Iron and Steel World, a well-known steel distribution center in China, with superior geographical position and convenient water and land transportation.
We are a direct-selling manufacturer specializing in the research and development of spiral steel pipes, steel coiled pipes, anti-corrosion steel pipes inside and outside. Since its inception, the company has been guided by a brand-new thinking of steel pipe product market based on the business philosophy of honesty, pragmatism and knowledge-seeking.
