2020-12-28 15:43:00

DIN 1630 ST37.4 seamless steel pipe is defined as: a steel pipe made of a single piece of metal without seams on the surface. According to the production method, seamless pipes are divided into hot rolled pipes, cold rolled pipes, cold drawn pipes, extruded pipes, and top pipes. According to the cross-sectional shape, seamless steel pipes are divided into two types: round and special-shaped. Special-shaped pipes have square, oval, triangle, hexagon, melon seed, star, and finned pipes.

DIN 1630 ST37.4 seamless steel pipe has a hollow section and are used as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, DIN 1630 ST37.4 seamless steel pipe is lighter in flexural and torsional strength and is an economical cross-section steel.

DIN 1630 ST37.4 seamless steel pipes is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames and steel scaffolding used in construction. Seam steel pipes improve material utilization, simplify manufacturing procedures, and save materials and processing time.
