  • Precision Seamless Steel Hydraulic Cylinder Honing Steel Pipe

    Hydraulic Honing Steel Pipe

    Hydraulic Honing Steel Pipe is a precision pipe manufactured through a honing process. Its interior surface undergoes a special treatment, resulting in exceptionally high smoothness and dimensional accuracy. Honing is a combined grinding and polishing process that effectively removes microscopic irregularities on the pipe’s interior surface, resulting in a mirror-like finish. Hydraulic Honing Steel Pipe is typically made from high-quality alloy steel or stainless steel and undergoes multiple processing steps to meet the needs of diverse industrial applications.

  • Pipeline Steel Pipe

    Pipeline Steel Pipe

    Pipeline steel pipes are pressure-bearing steel pipes specifically designed for transporting fluids such as oil, natural gas, and water. Their core characteristics are high strength, high toughness, good weldability, and corrosion resistance.

    Pipeline steel pipes are mainly divided into seamless pipes and welded pipes (straight seam/spiral welded pipes), conforming to API SPEC 5L or GB/T 9711 standards, with steel grades such as X42–X120 (yield strength 290–830 MPa).

    API SPEC 5L-2011 (Specification for Line Pipe), compiled and published by the American Petroleum Institute, is commonly used around the world. The main material of the pipe is L245, L290, L360, L415, L480, GR.B, X42, X46, X56, X65, X70, X80, X100 and other steel grades

  • SSAW Steel Pipe

    SSAW Steel Pipe

    SSAW Steel Pipe, also known as spiral submerged arc welded steel pipe, is a type of pipe made by rolling narrow steel strips into large-diameter pipes. The spiral weld seam improves overall mechanical properties, reduces cost, and is suitable for medium- and high-pressure fluid transportation and structural applications. However, the weld seam is relatively long, requiring strict quality control.

  • Welded steel pipe

    Welded Steel Pipe

    Welded steel pipe refers to a steel pipe with seams on the surface that is made by bending and deforming a steel strip or steel plate into a round, square or other shape and then welding it. The blank used for welded steel pipe is a steel plate or strip.

    Common materials for welded pipes include: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.
