Products Description
seamless steel pipeis made of perforated whole round steel, and the steel pipe without weld seam on the surface is called seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and pipe jacking. According to the cross-sectional shape, the seamless steel pipe is divided into two types: round and special-shaped. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes. Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemical industries, boiler pipes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation.
Welded steel pipe,also known as welded pipe, is a steel pipe made of steel plate or strip after crimping and welding, generally 6 meters. Welded steel pipe production process is simple, high production efficiency, variety specifications, less investment in equipment, but the general strength is lower than seamless steel pipe.Straight seam welded pipe, steel pipe made of hot or cold rolled steel plate or steel strip coil welding, straight seam welded pipe on welding equipment are called straight seam welded pipe.

manufacturer
We have professional equipment and technical engineers for your service, according to your requirements (material, shape, mechanical properties) customized production.Production field Part of products, Our company has automatic production line to produce round steel Good straightness, after chamfer, can be machined by the longitudinal cutting machine Customization (length)Customization (heat treatment hardness)Customization (Grinding machine polishing)
Principle
According to the production process, Steel round bar can be divided into three types: hot rolling, forging and cold drawing. The specification of hot-rolled steel round bar is 5.5-250mm. Among them: 5.5-25 mm small steel round bar are mostly supplied in straight strips, often used as steel round bar, bolts and various mechanical parts; Steel round bars larger than 25 mm are mainly used for manufacturing mechanical parts or as seamless steel pipe billets.
application
