Black Coating ASME SA106B DN200 Carbon Steel Seamless Pipe SCH40

Carbon steel seamless steel pipe is a kind of long strip steel. The steel pipe has a hollow section and is widely used as a pipeline for conveying fluid, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe has the same flexural and torsional strength and light weight. It is an economic section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as petroleum drill pipe, automobile drive shaft, bicycle frame and steel scaffolding used in construction.
Making ring parts with steel pipe can improve the utilization ratio of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing ring, Jack sleeve, etc. At present, steel pipe has been widely used to manufacture.
Steel pipe or all kinds of conventional weapons indispensable materials, barrel, barrel and so on are made of steel pipe. The steel pipe can be divided into round pipe and special-shaped pipe according to the shape of cross-sectional area. Because the circular area is the largest under the condition of equal circumference, more fluid can be transported by circular pipe. In addition, the ring section under internal or external radial pressure, the force is more uniform, therefore, most of the steel pipe is a circular pipe.
Making ring parts with steel pipe can improve the utilization ratio of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing ring, Jack sleeve, etc. At present, steel pipe has been widely used to manufacture.
It is divided into 10# seamless steel pipe ,20# seamless steel pipe ,4# seamless steel pipe and so on.

Material factors
(1) The importance of structure The importance of heavy-duty industrial building structures, long-span structures, high-rise or super-high-rise civil building structures or structures, etc., should consider the selection of seamless steel pipes of good quality, and for general industrial and civil building structures, the selection of seamless steel pipes of ordinary quality can be made according to the nature of work.
(2) Seamless steel pipes with good comprehensive performance should be used for structures directly bearing dynamic loads and those in strong seismic zones under load conditions, while seamless steel pipes with lower prices can be used for structures generally bearing static loads.
(3) The welding process of the connection method results in welding deformation, welding stress and other welding defects, and there is a risk of cracks or brittle fracture of the structure. Therefore, the welding structure should be strict with the material requirements.
(4) In the temperature and environment of the structure, seamless steel pipe is easy to be cold and brittle at low temperature, so the structure working at low temperature, especially the welding structure, should choose the sedative steel with good resistance to low temperature brittle fracture. In addition, Taiyuan seamless steel pipe with open-air structure is easy to produce aging, and seamless steel pipe with harmful medium is easy to corrode, fatigue and fracture, so different materials should be selected differently.
(5) Too seamless steel pipe thickness, thin seamless steel pipe roll rolling times, rolling compression ratio is large, the thickness of seamless steel pipe compression ratio is small, so the thickness of precision steel pipe not only less strength, but also poor plasticity, impact toughness and welding performance. Therefore, the welding structure with large thickness should be [1] with seamless steel pipe with good material.
