 L245Q seamless steel pipe is a hollow section, no seams around the strip steel. Steel pipe has a hollow section, a large number of used for conveying fluid pipe, such as oil, natural gas, coal gas, water and some solid materials, such as pipelines. Compared to the steel pipe and round steel solid steel bending torsional strength phase at the same time, the weight is lighter, is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts, such as petroleum drill pipe, auto transmission shaft, bicycle frame and construction of steel scaffolding is used. With steel pipe manufacturing annular parts, can improve material utilization, simplifying the manufacturing process, material saving and processing time, such as rolling bearing ring, jack sets, at present has been widely made from carbon steel pipe. Steel pipe or all kinds of conventional weapons indispensable materials, gun, gun barrel to steel pipe manufacturing. Steel pipe according to the cross-sectional area in the shape of different can be divided into circular tube and special pipe. Due to the equal conditions, the circumference circle area is the largest, with circular tube can deliver more fluid. In addition, the circle cross section under radial pressure, the internal or external stress is relatively uniform, therefore, the vast majority of steel tube is round tube. But, pipe also has some limitations, such as in the plane bending condition, the pipe is not square, rectangular tube bending strength is big, some agricultural machinery and skeleton, rectangular tube, steel wood furniture is commonly used. According to the different USES also needs to have other cross section shape of profiled steel pipe. Classification of seamless steel tube Seamless steel pipe according to the manufacturing methods are divided into hot rolling and cold drawing (rolling) tube. Cold drawing (rolling) tube maximum nominal diameter is 200 mm, maximum nominal diameter is 600 mm hot rolling pipe. In pipeline engineering, more than 57 mm diameter, often choose hot-rolled tube, pipe diameter less than 57 mm often used pipe cold drawing (rolling). Pipeline engineering commonly used seamless steel pipe has the following three kinds: 2.1 the general seamless steel tube General seamless steel tube or seamless steel tube, using ordinary carbon steel, quality carbon steel, low alloy steel and alloy steel manufacturing, used for conveying liquid pipe or production structure, parts made with. Seamless steel pipe according to outer diameter and wall thickness of supply, a variety of wall thickness under the same outer diameter, pressure range is larger. Usually mild steel pipe length, hot-rolled tube is 3-12.5 m, cold drawing (rolling) tube is 1.5 to 9 m. 2.2 low medium pressure boiler seamless steel tube medium pressure boiler seamless steel tube is made of 10, 20 quality carbon steel, the working temperature.   More information,pls visit:Hunan great steel pipe co.Health Fitness Articles,ltd
