Tubo sem costura de aço carbono

Carbon steel seamless pipe is a kind of long steel. Steel Pipe has a hollow cross-section, a large number of pipelines used for conveying fluids, como o petróleo, gás natural, Gás, water and some solid materials pipelines.
Steel pipe and solid steel, such as the strength of the flexural torsion, the same time, light weight, is an economic section of steel, Amplamente utilizado no fabrico de peças estruturais e peças mecânicas, tais como tubos de perfuração de petróleo, automobile transmission shaft, bicycle racks and construction of steel scaffolding, etc.
Making annular parts with steel pipe can improve material utilization, simplify manufacturing process, save material and working hours, such as rolling bearing ring, Jack sleeve, etc., which is now widely used in steel pipe manufacture. Steel pipe or a variety of conventional weapons indispensable materials, barrel, barrel, etc. to be made of steel pipe. The steel pipe can be divided into round pipe and irregular pipe according to the cross-sectional area shape. Due to the same circumference, the circle area is the largest, with a circular tube can transport more fluids.
Além disso, the Ring section is subjected to internal or external radial pressure, the force is more uniform, Portanto,, the vast majority of steel pipe is round pipe.
Making annular parts with steel pipe can improve material utilization, simplify manufacturing process, save material and working hours, such as rolling bearing ring, Jack sleeve, etc., which is now widely used in steel pipe manufacture.
Divided into 10# Tubos de aço sem costura, 20# Tubos de aço sem costura, 45# Tubos de aço sem costura. Seamless steel tube with hollow section, a large number of pipelines used for conveying fluids, como o petróleo, gás natural, Gás, water and some solid materials pipelines.
Compared with solid steel, such as steel pipe, the flexural and torsional strength is the same, and the weight is lighter, which is an economic section steel.
Amplamente utilizado no fabrico de peças estruturais e peças mecânicas, tais como tubos de perfuração de petróleo, automobile transmission shaft, bicycle racks and steel scaffolding used in building construction, such as the production of annular parts, can improve material utilization, simplifying manufacturing processes, saving materials and processing hours, has been widely used in steel pipe manufacturing. A propriedade mecânica do aço é um índice importante para garantir o uso final do aço, que depende da composição química e do sistema de tratamento térmico.

No padrão de tubo de aço, de acordo com os diferentes requisitos de uso, as propriedades de tração (Resistência à tração, intensidade de rendimento ou ponto de rendimento, Alongamento) bem como dureza, índice de tenacidade, e requisitos do usuário de desempenho de alta e baixa temperatura. Seamless steel tubes are divided into hot-rolled and cold-rolled (dial) Tubos de aço sem costura. laminado a quente TUBULAÇÃO DE AÇO SEM COSTURA, low and medium pressure boiler pipe, high-pressure boiler pipe, Tubulação De Aço De Liga, cano de aço inoxidável, petroleum cracking pipe, geological steel pipe and other steel pipe. laminados a frio (dial) Tubo De Aço Sem Costura, in addition to general steel pipe, low medium pressure boiler pipe, high-pressure boiler pipe, Tubulação De Aço De Liga, cano de aço inoxidável, petroleum cracking pipe, other steel pipe, but also includes carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless steel thin-walled steel pipe, profiled pipe
Hot-rolled seamless pipe diameter is generally greater than 32mm, wall thickness 2.5-75mm, cold rolled seamless pipe diameter can be to 6mm, wall thickness can be 0.25mm, thin-walled tube diameter can be to 5mm wall thickness is less than 0.25mm, cold-rolled than hot-rolled size precision. The general use of TUBULAÇÃO DE AÇO SEM COSTURA is used 10#, 20#, 30#, 35#, 45# and other high-qualidade carbon steel 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40etc, such as steel hot-rolled or cold-rolled. Seamless steel tubes made of 10#, 20#, etc. are mainly used in fluid conveying pipelines. 45, 40Cr and other carbon steel made of seamless pipe used to make mechanical parts, such as automobiles, tractors, the force of parts. General use of seamless steel tube to ensure strength and flattening test.
The hot-rolled steel pipe is delivered in hot rolling or heat treatment condition. Hot-rolled seamless steel tube, as the name suggests, the temperature of the rolled pieces is high, so the deformation resistance is small, can achieve large deformation. Taking the rolling of steel plate as an example, the thickness of continuous casting slab is about 230mm, and after roughing and fine rolling, the final thickness is 1~20mm. Ao mesmo tempo, because of the small size of the steel plate, the dimension precision is relatively low, it is not easy to appear the problem of flatness, to control the convexity. The microstructure and mechanical properties of strip steel can be controlled by controlling rolling temperature, finish rolling temperature and crimp temperature in order to achieve the requirements of the Organization.
