Production of hot-rolled seamless steel tubes, cold drawn seamless steel tubes, precision seamless steel tubes, thermal expansion seamless steel pipe, alloy seamless steel pipe. You can also build processing pipe, rectangular seamless steel pipe, seamless steel centrifugal casting, large diameter thick wall straight seam steel (polished welds can be testing, strength and even comparable with seamless steel pipe, can be widely Applications and large mechanical parts processing, network structure, project pipelines, piling column, fluid transport, hydraulic manufacturing and other fields). The company and maintain perennial partnership with Chengdu Iron and Steel Group, China Metallurgical Steel Group, Baotou Steel Plant, Baosteel Group, Anshan Iron and Steel Group, Tianjin Seamless Steel Tube Plant, Xining Te steel, Wuxi Steel Plant, Hengyang Steel Plant, etc., become the local level agents. Where is seamless and welded steel pipe difference? 1. Appearance, seamless and welded steel pipe inner wall welding difference in muscle, but there is no seamless. 2. The higher pressure seamless, welded pipe is generally about 10 MPa, and now have to do seamless pipe processing. 3. seamless steel pipe was rolling a molding. Welded steel pipe welded need rolled back, generally spiral welded and straight welding. Seamless performance is better, of course, price is also higher. The tube is a hollow steel bar, a large number of channels for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, engaged in bending, torsional strength, lighter weight, so it is widely used in the manufacture of mechanical parts and engineering structures. Also used in producing a variety of conventional weapons, the barrel, shells and so on. Classification of steel pipe: seamless and welded steel pipe points (pipe joints) two categories. Press the cross-sectional shape can be divided into tube and shaped pipe boiler pipe, widely used in construction is a circular steel pipe, but there are some square, rectangular, semi-circular, hexagonal, equilateral triangle, octagon shaped steel tubing, etc. . For withstand fluid pressure hydraulic pipe must withstand the test of capacity and quality, leakage does not occur at a predetermined pressure, wet or expansion of qualified, but also according to some standard or steel demand side, curling trials , flaring test, flattening test. Seamless steel pipe: seamless steel ingot is made of perforated or solid through the capillary tube, and then by the hot-rolled, cold-rolled or cold call is made. Seamless steel pipe wall thickness specifications mm diameter * number indicates. Hot and cold rolled seamless steel pipe points (written) seamless steel categories. Hot-rolled seamless steel pipe sub-normal, low, medium pressure boiler pipe, high pressure boiler pipe, steel pipe, stainless steel pipe, oil cracking pipe, steel and other steel and other geological.
