  • Fine drawn seamless alloy tube cold drawn hollow round tube

    Fine drawn seamless alloy tube cold drawn hollow round tube

    Alloy tube is divided into seamless tube structure and high pressure heat resistant alloy tube. It is mainly different from the production standard of alloy tube and its industry. The alloy tube is annealed and conditioned to change its mechanical properties. Its performance than the general seamless steel pipe variable utilization value is higher, high temperature resistance, low temperature resistance, corrosion resistance.

  • Precision inside and outside brightening tube

    Precision inside and outside brightening tube

    Precision bright tube is a kind of high precision steel tube material after finishing drawing or cold rolling. Because there is no oxide layer on the inner and outer walls of the precision bright tube, no leakage under high pressure, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and so on, it is mainly used for the production of pneumatic or hydraulic components.

  • Stainless steel elliptic flat elliptic tube with fan-shaped groove

    Stainless steel elliptic flat elliptic tube with fan-shaped groove

    Shaped tubes are widely used in various structural parts, tools and mechanical parts. Compared with the round tube, the special-shaped tube generally has a larger moment of inertia and section modulus, has a larger bending and torsional resistance, can greatly reduce the weight of the structure, save steel.

  • 304 stainless steel seamless welded carbon acoustic steel pipe

    304 stainless steel seamless welded carbon acoustic steel pipe

    Stainless steel seamless pipe is resistant to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical etching medium corrosion of steel pipe, the thicker the wall, it is more economical and practical, the thinner the wall thickness, its processing cost will rise substantially. In bending, torsional strength is the same, light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures.

  • Welded steel pipe large diameter thick wall steel

    Welded steel pipe large diameter thick wall steel

    It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip according to a certain spiral angle(called forming angle) into a tube blank, and then welding the tube seam together. It can be made with a narrower Strip steel produces large diameter steel pipes. Its specifications are expressed by outer diameter * wall thickness, and the welded pipe shall be ensured that the hydraulic test, the tensile strength of the weld and the cold bending performance must meet the requirements.

  • Anticorrosive large diameter composite inner and outer coated plastic steel pipe

    Anticorrosive large diameter composite inner and outer coated plastic steel pipe

    Suitable for buried and humid environment, and can withstand high and very low temperatures. Strong anti-interference ability, good strength under pressure, good insulation performance.

    With the advantages of high strength of steel pipe, easy connection, water impact resistance, but also overcome the steel pipe in water corrosion, pollution, scaling and plastic pipe strength is not high, poor fire performance and other shortcomings.

  • Construction square rectangular pipe welded black steel pipe

    Construction square rectangular pipe welded black steel pipe

    Stainless steel square tube is a hollow strip of steel, because the section is square so called square tube. A large number of pipelines used for conveying fluids, such as oil, natural gas, water, gas, steam, etc., in addition, in bending, torsional strength at the same time, light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures.

  • DN20 25 50 100 150 Galvanized steel pipe

    DN20 25 50 100 150 Galvanized steel pipe

    Galvanized pipe, also known as galvanized steel pipe, divided into hot dip galvanized and electric galvanized two, hot dip galvanized galvanized layer thick, with uniform coating, strong adhesion, long service life and other advantages. The cost of galvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipe. Mainly used for conveying gas and heating.
