  • Galvanized Steel Pipe

    1. Galvanized steel pipe surface after stab-proof treatment, more durable, oxidation speed should not be too fast.

    2. The steel pipe is protected by zinc and the concave and convex parts are protected when heated.

    3. It has corrosion resistance, wear resistance and longer service life of steel pipe.

    4. Galvanized on the surface of steel pipe, construction is more convenient.

    5. Galvanized pipes are suitable for cold areas.

  • Straight Seam Steel Pipe

    Straight - seam steel pipe is a steel pipe that is longitudinally parallel to the weld line. It is usually divided into metric welded steel pipe, welded thin wall pipe, transformer cooling pipe and so on. The production process of straight seam welded pipe is simple, the production efficiency is high, the cost is low, the development is fast. The strength of spiral welded pipe is generally higher than that of straight welded pipe.

  • Seamless Steel Tube

    A seamless steel tube made of whole metal with no seams on the surface is called a seamless steel tube. According to the production method, seamless pipe is divided into hot rolled pipe, cold rolled pipe, cold drawn pipe, extrusion pipe, top pipe, etc. According to the section shape, seamless steel pipe is divided into two types: circular and irregular. The shaped pipe has many complex shapes, such as square, oval, triangle, hexagonal, melon seed, star and winged pipe. The diameter is up to 650mm, and the minimum diameter is 0.3mm.

  • Oil Casing

    Oil casing is the steel pipe used to support the wall of oil and gas well to ensure the normal operation of the whole oil well during and after drilling. Each well USES several layers of casing, depending on its depth and geology. Cement cementing should be adopted after casing drilling. It is different from tubing and drill pipe and cannot be reused. It is a disposable material. Therefore, the consumption of casing accounts for more than 70% of the total well pipe.

  • Spiral Steel Pipe

    Spiral steel pipe is a spiral seam steel pipe with steel coil as the raw material, which is usually formed by warm extrusion and welded by automatic double wire and double submerged arc welding process. Spiral steel pipe will strip into welded pipe unit, the multichannel roll rolling, strip steel rolled up gradually, there is an open space form of round billet, adjust the quantity of the squeezing roller, make the weld gap control in 1 ~ 3 mm, and make joint flush on both ends.

  • Alloy Steel Pipe

    Alloy steel pipe is primarily used for power plant, nuclear power, high pressure boiler, high temperature superheater and reheater of high-temperature high-pressure pipeline and equipment, it is made of high quality carbon steel, alloy structural steel and heat resistant stainless steel material, by hot rolling (crowded, expanding) or cold rolling (drawing).

  • Anti-Corrosion Steel Pipe

    Anticorrosive steel pipe is a kind of steel pipe which is processed by anticorrosion technology and can effectively prevent or slow down the corrosion caused by chemical or electrochemical reaction during transportation and use. According to China's statistics, the direct economic loss of steel pipe corrosion is more than 280 billion yuan per year.

  • Thermal Insulation Pipe

    Thermal insulation pipe (Heat preservation pipe) is after processing the Heat preservation technology, in different working conditions and medium to ensure work steel pipe under the action of outside temperature and surface temperature meet or meet the use requirements of steel pipe.
