What are the cutting methods of thick-walled spiral steel pipe
1. The mechanical cutting of thick-walled spiral steel pipe adopts two types of external installation and internal installation. It uses the principle of turning tool processing to cut and groove the nozzle. The single machine has a large span, a large thickness that can be processed, less waste,...Read more -
Technical characteristics of double-sided submerged arc welding spiral steel pipe
1. During the forming process of the spiral steel pipe, the deformation of the steel plate is uniform, the residual stress is small, and the surface does not produce scratches. Processed steel pipes have greater flexibility in the range of diameter and wall thickness of steel pipes, especially in...Read more -
Advantages of spraying polyurethane wear-resistant and anti-corrosion coating materials on steel pipes
In addition to the excellent chemical corrosion resistance, strong adhesion, and mechanical damage resistance as the outer wall anti-corrosion layer, the steel pipe lining also needs excellent wear resistance. Polyurethane wear-resistant and anti-corrosion coating materials are different from gen...Read more -
What materials will be used in the anti-corrosion treatment of spiral steel pipes
The materials used for the anti-corrosion processing of spiral steel pipes play a decisive role in the quality of anti-corrosion steel pipes. During anti-corrosion processing, raw materials must be strictly tested. Different anti-corrosion processing requires different anti-corrosion materials. 1...Read more -
Precautions when welding spiral steel pipe
It is inevitable to weld and cut the spiral steel pipe structure in the application of spiral steel pipe. Due to the characteristics of the spiral steel pipe itself, compared with ordinary carbon steel, the welding, and cutting of the spiral steel pipe have their particularity, and it is easier t...Read more -
What materials can be used for steel pipeline anticorrosion coating
Steel pipeline anti-corrosion coatings include petroleum asphalt, PE jacket and PE foam jacket, epoxy coal tar pitch, coal tar enamel paint, epoxy powder and three-layer composite structure, epoxy coal pitch cold wrap tape (PF type), rubber and plastic ring Oxygen coal tar pitch cold wrapping tap...Read more
