Seamless production of classification - hot-rolled pipes, cold-rolled pipes, cold-drawn tubes, extruded tubes, pipe jacking Stainless steel tubing is a hollow cross-section, not the joints surrounding the steel bar. Steel tube with a hollow cross-section, a large number of pipes used for conveying fluids, such as transmission oil, natural gas, gas, water and some solid materials, such as pipelines. Steel tube with solid steel round bar, etc. as compared to the flexural torsional strength in the same light, is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automotive transmission shaft, bicycles aircraft, as well as building construction, such as using steel scaffolding.
With steel pipe manufacturing annular parts, can improve material utilization, simplify the manufacturing process, saving material and machining time, such as roller bearing rings, Jack sets and so on, has been widely used to manufacture steel pipes or a variety of conventional weapons an indispensable material, barrel, barrel must be steel pipe, etc. to create. Steel tube by cross-sectional area can be divided into different shapes tube. Because of the circumference of the same conditions, the largest circle, using a circular tube can be more fluid delivery. In addition, the ring cross-section in the bearing radial internal or external pressure, the force more evenly, so the vast majority of tubular are .
From international and domestic markets, the seamless steel pipe (including OCTG) are larger than the existing production capacity needs. Therefore, future emphasis should be placed on giving full play to the capacity of existing units to develop a high-strength grades, high against damage, high anti-corrosion of oil pipes, high-pressure boiler tubes and tube products such as cylinders. My country is the current steel market to optimize the product structure of the content. This is also to increase the competitiveness of their products at home and abroad, and expand market share in the key. In other words, improve the domestic stainless steel tubing market competitiveness of enterprises and the WTO are added after the long-term task of domestic enterprises and the key to successful development.
