Long-distance oil and gas pipelines are an important way to ensure energy. In the process of anti-corrosion construction of oil and gas pipelines, the surface treatment of straight seam steel pipes is a key factor in determining the service life of pipeline anti-corrosion. It is the premise of wheth

304 stainless steel pipe is the most widely used as stainless heat-resistant steel, food equipment, general chemical equipment, and atomic energy industry equipment. 304 stainless steel pipe is a general-purpose stainless steel pipe, which is widely used to make equipment and parts that require good

At present, there are many applications of reinforced 3pe anti-corrosion steel pipes. However, due to the low precision of the wall thickness of reinforced 3pe anti-corrosion steel pipes, there is a phenomenon of uneven thickness, which will have a great impact on the performance of reinforced 3pe a

Maybe you have never paid attention to such details, you must choose a suitable venue and warehouse to save the spiral steel pipe. 1) The site or warehouse for storing spiral steel pipe products should be selected in a clean and well-drained place, away from factories and mines that generate harmful

Coating anti-corrosion is an average dense coating formed on the surface of the rust-removing metal pipe, and its coating can isolate it from various corrosive media. Steel pipe anti-corrosion coatings are increasingly using composite materials or composite structures. These materials and structures

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

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

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

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

Spiral steel pipes are mainly used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. Spiral steel pipes are twenty key products developed in my country.For liquid transportation: water supply, drainage. For gas
