The defects that are prone to occur in the welded area of the spiral steel pipe include pores, hot cracks, and undercuts.The porosity of the welded seam of the spiral steel pipe not only affects the tightness of the welding seam of the pipeline and causes the leakage of the pipeline, but also become
Plastic-coated composite steel pipe is a new type of pipeline material recently developed in China. It adopts a plastic-coated protective layer inside and outside, and the middle is a composite structure of reinforced welded steel pipe or seamless pressure-bearing steel pipe, which overcomes the eas
The processing methods of 3pe anti-corrosion steel pipes are generally divided into two types: winding type and round mold wrapping type; they are all composed of a 3-layer structure: the first layer of epoxy powder (FBE>100um), the second layer of adhesive (AD) 170 ~ 250um, The third layer of polye

The production of anti-corrosion and thermal insulation steel pipes needs to be produced according to national standards. Different processing methods follow different standards, but they must conform to the national production standards and must be strictly followed and implemented. At present, the
Welding equipment: ZX7-400-3 welding machine is used for root welding; multifunctional automatic steel pipe welding equipment is used for filling and capping.Welding materials: φ3.2 E6010 cellulose electrode is used for root welding; Lincoln E81T8-G φ2.0 flux-cored self-shielded welding wire is used
a. Powder coating, which is a new type of coating that does not contain solvent and is formed by melting powder. Epoxy powder coating is commonly used in anti-corrosion engineering. Compared with traditional solvent-based anti-corrosion coatings, it has the advantages of no solvent pollution, conven
Selection of anti-corrosion coatings for steel pipesThere are a wide variety of anti-corrosion coatings, and their properties and uses are different. Correct selection is crucial to the anti-corrosion effect and service life of the coating. When choosing, you should consider:1. Surface material prop
