Carbon Steel Seamless Pipe DIN 17175 ST45 Seamless Carbon Steel Pipe DN 750 XS Hot Rolled Oiled
Overview
Carbon steel seamless steel pipe is a kind of long strip steel with hollow section and no joint around it. 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.
Cold drawn (rolled) carbon steel seamless steel pipe: pipe billet → heating → perforation → head → annealing → pickling → oiling (copper plating), multi-pass cold drawing (cold rolling)→ billet pipe heat treatment → straightening water pressure test (flaw detection)→ marking and storage
Carbon steel seamless steel pipe is divided into hot rolled (extruded) seamless steel pipe and cold drawn (rolled) seamless steel pipe because of its different manufacturing technology. Cold drawing (rolling) tube is divided into circular tube and special-shaped tube.
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 good quality Taiyuan seamless steel pipe, for general industrial and civil building structures, according to the nature of the work can be selected common quality Taiyuan seamless steel pipe. (2) In the case of load, Taiyuan seamless steel pipe with good comprehensive performance should be selected for the structure directly bearing the dynamic load and the structure in the strong seismic zone, while Taiyuan seamless steel pipe with lower price can be used for the structure generally bearing the static load. (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.
