    The so-called seamless carbon steel seamless pipe stainless steel and carbon steel seamless pipe difference, mainly refers to the stainless steel and carbon steel in the design rules, the differences that the two steel design rules can not be universal. These points differences are summarized as follows: Stainless steel design rules can not be used because the stainless steel and carbon steel have enjoyed three fundamental difference: First, the cold hardening steel produced, for example, anisotropic bending, namely: the horizontal and vertical different properties. Can increase the strength of the cold working, but if compared with the total area of the bending area is negligible small and this increase, the intensity increased to a certain extent improve the safety factor. Second, the stress / strain curves of different shapes, the elastic limit of the stainless steel is about 50% of yield stress, the minimum value specified in the standard is concerned, the yield stress value below the yield stress of carbon steel. Third, the stainless steel does not yield point, usually ó0.2 to indicate that the yield stress is considered to be equivalent value. Factory production of cold rolled precision light control system looks smooth, uniform thickness, no oxide layer, high precision. carbon steel seamless pipe bore can be divided into round, splined, plum-type are widely used in automobiles, motorcycles, power, petrochemical, shipbuilding, aerospace, bearings, pneumatic components, fuel tanks, boiler equipment, medical equipment, fitness equipment and other industries. Material can be divided into: 10 #, 20 #, 35 #, 45 #, GCr15, 40Cr,16Mn and so on. According to user needs all kinds GB non-target precision tube.Special material specifications can be booked in advance, the company has 60 fine drawing unit 2, 50 fine drawing machine, 3 sets of production outside diameter 10-90mmwall thickness 1-14mm precision carbon steel seamless pipe, made of 10 #, 20 #, 45 #,16Mn , 20Cr , 40Cr. According to user needs all kinds GB non-target precision tube.Special material specifications can be booked in advance. Plastic composite pipe with hot dip galvanized carbon steel seamless pipe as a matrix, the powder coating technology in the molten inner (outer wall also needed) made of plastic coating performance.

    Compared with galvanized pipe, with anti-corrosion, no rust, no fouling, smooth smooth, clean non-toxic, long life and other advantages.According to tests, the service life of plastic composite pipe galvanized pipe more than three times. Compared with plastic pipe, with high mechanical strength, pressure, heat resistance and good. Since the base body is a carbon steel seamless pipe,so there is no embrittlement aging. It can be widely used in water, gas, chemical products and other fluid transport and heating engineering, galvanized pipe upgrade products. Since its installation method is basically the same traditional galvanized pipe, fittings forms are identical, and can replace plastic composite pipe in large diameter water transmission play a role, welcomed by users and has become the most competitive pipeline market new products. Coated carbon steel seamless pipe in large diameter spiral welded pipe and high-frequency welded pipe made of plastic coating on the basis of the maximum nozzle diameter up to 1200mm, can be coated with polyvinyl chloride according to different needs (PVC), polyethylene (PE) epoxy resin (EPOZY) and other various properties of plastic coating, good adhesion, corrosion resistance, can be resistant to acid, alkali and other chemical corrosion, non-toxic, does not rust, abrasion resistance, impact resistance, permeability, smooth pipe surface, do not adhere to any substance that can reduce transmission of resistance, increase traffic and transportation efficiency, reduce delivery pressure loss. Coating solvent-free, no leaking substances, and thus will not contaminate the transmission medium, thus ensuring fluid purity and hygiene at -40 ℃ to +80 ℃ range can be used alternately hot and cold cycles, aging, no cracks, which can in cold areas such harsh environments.
