DIN 1629 ST37 20 Inch SCH 80 12m Carbon Steel Seamless Pipe Hot Rolled

DIN 1629 ST37 Seamless Carbon Steel Pipe, 20 Inch, SCH 80, 12 Meter, Hot Rolled.

Carbon steel pipe can be divided into seamless steel pipe, straight seam steel pipe, spiral steel pipe, high frequency welded steel pipe and so on. The raw material of rolling seamless carbon steel pipe is round tube billet. The round tube embryo must be cut by cutting machine to process the billet with a growth degree of about 1 meter, and sent to the furnace by conveyor belt for heating. After extrusion, take off the pipe and set the diameter. The diameter fixing machine rotates into the steel embryo through the conical bit at high speed to form the steel pipe. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit. After the steel pipe is fixed, it enters the cooling tower and is cooled by water spray. After cooling, the steel pipe will be straightened. The steel pipe is straightened and sent from conveyor belt to metal flaw detector (or hydraulic test) for internal flaw detection. If there are cracks, bubbles and other problems inside the steel pipe, it will be detected. Steel pipe quality inspection but also through strict manual selection. After quality inspection of steel pipe, spray the number, specification, production batch number and so on with paint. And crane into the warehouse.

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.
