20Cr- JIS:SCr22 Carbon Steel Pipe Krobo Steel

Product Introduction 

20Cr steel pipe has a hollow section and is widely used as a pipeline for transporting fluids, such as transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, when the bending and torsional strength is the same, the weight is lighter. 20Cr seamless steel pipe is an economical section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission Axles, bicycle racks, and steel scaffolding used in building construction, etc. The use of 20Cr steel pipes to manufacture ring parts can improve material utilization, simplify manufacturing processes, save materials and processing hours, such as rolling bearing rings, jack sets, etc., which have been widely used in steel pipes. 20Cr seamless steel pipe is also an indispensable material for various conventional weapons, and the barrel, barrel, etc. must be made of steel pipe. 20Cr steel pipes can be divided into round pipes and special-shaped pipes according to the shape of the cross-sectional area. Due to the condition that the circumference is equal, the area of the circle is the largest, and more fluid can be transported with a circular tube. In addition, when the ring section is subjected to internal or external radial pressure, the force is relatively uniform, so most steel pipes are circular pipes.

Application:

20Cr steel pipe has a hollow section and is widely used as a pipeline for transporting fluids, such as transporting oil, natural gas, gas, water and certain solid materials.

Widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding used in building construction, etc.

Classification By Size:

The length is generally 6000mm, 1250mm,2200mm,12000mm, and the thickness is distinguished by cold rolling and hot rolling. Cold rolling mainly has thickness 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm. The main thickness of hot rolling is 3.0mm, 4.0mm, 6.0mm, 8.0mm, 10.0mm, and the width is generally 1000mm, 1219mm, 1500mm.Please contact customer service for general specifications.

 

Hot-rolled carbon steel pipe are produced by continuous hot-rolled carbon steel technology with hot-rolled steel strip or cold-rolled steel strip as the substrate. The hot-rolled carbon steel sheet is supplied as a rectangular flat plate by cross-cutting; the hot-rolled carbon steel sheet is supplied in coil form by coiling, and the hot-rolled carbon steel sheet coil can be divided into hot-rolled carbon steel sheet coil and cold-rolled carbon steel sheet Coils, they are mainly used in construction, home appliances, automobiles, containers, transportation and household business and other fields. Especially steel structure construction, automobile manufacturing, steel silo manufacturing and other industries.

 

Their main features are: strong corrosion resistance, good appearance quality, benefit from deep processing, economical and practical, etc.

Application range:

(1) After annealing, it is processed into ordinary cold rolling;

(2) The galvanizing unit with pre-annealing treatment device processes galvanizing;

(3) Panels that basically do not need to be processed.
