  • Comparison between plastic-coated steel pipes and 3PE anti-corrosion steel pipes

    Comparison between plastic-coated steel pipes and 3PE anti-corrosion steel pipes

    Plastic-coated pipes, also known as plastic-coated steel pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, are based on steel pipes and use PE (modified polyethylene) for hot dip molding or EP (epoxy resin) as the main anti-corrosion raw material. It is a steel-plast...

  • Comparison of the advantages and disadvantages of spiral steel pipe and straight steel pipe welds

    Comparison of the advantages and disadvantages of spiral steel pipe and straight steel pipe welds

    The weld seam of spiral steel pipe is longer than that of straight seam steel pipe. If the pipe length is L, the weld seam length is L/cos(θ). Most of the defects in steel pipes are concentrated in the welds and heat-affected zones. Long welds mean a high probability of defects. This is the main ...

  • How to detect plastic-coated steel pipes

    How to detect plastic-coated steel pipes

    Plastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, are based on steel pipes. A layer of plastic anti-corrosion layer or plastic anti-corrosion layer is fused to the inner surface of the steel pipe (bottom pipe) ...

  • What is coated steel pipe

    What is coated steel pipe

    Coated steel pipes are coated with plastic based on large-diameter spiral welded pipes and high-frequency steel pipes, with a maximum pipe diameter of 1200mm; they can be coated with polyvinyl chloride (PVC), polyethylene (PE), and ring-shaped steel pipes according to different needs. Oxygen resi...

  • Introduction of 316L stainless steel thick wall steel pipe

    Introduction of 316L stainless steel thick wall steel pipe

    316L stainless steel thick-walled steel pipe is a molybdenum-containing stainless steel. Because the steel contains molybdenum, the overall performance of this steel is better than 310 and 304 stainless steel. Under high-temperature conditions, when the concentration of sulfuric acid is lower tha...

  • Analysis of accidents prone to occur on the heating surface of boiler steel tubes

    Analysis of accidents prone to occur on the heating surface of boiler steel tubes

    Boiler heating surface pipes work for a long time under the action of high temperature, stress, and corrosive media. When the steel pipes cannot withstand the load of their working conditions, different forms of damage will occur and cause accidents. Common accidents on heating surface pipes of b...

  • How to identify the quality and authenticity of alloy steel tubes

    How to identify the quality and authenticity of alloy steel tubes

    For alloy pipe magnets, verify their quality and authenticity. If they do not attract magnets, they are considered good and genuine; if they attract magnets, they are considered counterfeit. In fact, this is an extremely one-sided, unrealistic, and wrong method of identification. There are many t...

  • Galvanized steel pipe details

    Galvanized steel pipe details

    Welded steel pipes with hot-dip or electro-galvanized layers on the surface. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water,...

  • Surface treatment of thick-walled straight seam steel pipes

    Surface treatment of thick-walled straight seam steel pipes

    The uniformity of the wall of thick-walled straight-seam steel pipes will directly affect the later processing of parts. The wall of thick-walled straight-seam steel pipes cannot be controlled, which means that the overall steel pipe cannot be strictly controlled. Small and medium-sized steel, wi...

  • Diameter expansion technology and detection methods of straight seam steel pipes

    Diameter expansion technology and detection methods of straight seam steel pipes

    Generally speaking, the diameter of the pipe can be divided into outer diameter, inner diameter, and nominal diameter. The outer diameter of a pipe whose material is a straight seam steel pipe is represented by the letter D, followed by the outer diameter size and wall thickness. For example, a s...

  • Wall thickness accuracy and straightening method of straight seam steel pipes

    Wall thickness accuracy and straightening method of straight seam steel pipes

    Controlling the wall thickness of straight seam steel pipes is a difficulty in steel pipe production. At present, the methods for wall thickness accuracy in production by straight seam steel pipe manufacturers generally include: 1. Heating of tube blanks: Heating should be even and avoid rapid te...

  • Hot rolling and cold rolling of stainless steel

    Hot rolling and cold rolling of stainless steel

    Hot rolling and cold rolling are both processes for forming steel sections or steel plates. They have a great impact on the structure and properties of steel. The rolling of steel is mainly hot rolling, while cold rolling is only used to produce small sections of steel and thin plates. 1. Hot rol...
