Seamless steel pipe is a kind of long steel with hollow section and no joints around, which is widely used in many fields. Its production methods include hot rolling, cold rolling, cold drawing, extrusion and pipe top, etc. According to the different section shape, seamless steel pipes can be divided into two kinds of round and shaped, shaped tubes including square, oval, triangle, hexagonal and fin tube and other complex shapes. The specification range of seamless steel pipe is wide, the maximum diameter can reach more than 650 mm, the minimum diameter is 0.3 mm, according to the different use, can be divided into thick wall pipe and thin wall pipe.

Seamless steel pipe is a steel pipe made of a whole piece of metal with no seam on the surface. This kind of steel pipe according to the production method is divided into hot tie pipe, cold tie pipe, etc., seamless steel pipe is rolled by ordinary carbon structural steel, low alloy structural steel or alloy structural steel, the outer diameter of seamless steel pipe is generally from 6mm to 830mm, the wall thickness can be from 0.8mm to 60mm, the length is generally 3m to 12m, and there are customized lengths according to demand.
Seamless steel pipe production line, which is mainly composed of a number of equipment, including heating furnace, tube rolling machine, cooler, flaw detection machine and so on. The working principle of steel pipe production line is to transform the billet into seamless steel pipe by rolling, drawing and other processes at high temperature. The seamless steel pipe produced by the steel pipe production line has good processing performance, stable and reliable quality, and is widely used in petroleum, chemical industry, machinery manufacturing and other fields.
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
