The production process of seamless steel pipe

① Main production process of hot rolled seamless steel pipe (△ main inspection process) : Preparation and inspection of tube blank △ heating of tube blank → perforation → Rolling pipe → reheating of steel pipe → fixing (reducing) diameter → heat treatment △ straightening of finished pipe → finishing → inspection △ (non-destructive, physical and chemical, table inspection) → storage

What are the uses of seamless steel pipe

Seamless steel pipe has hollow section, widely used for conveying fluid pipeline, such as conveying oil, natural gas, gas, water and some solid materials, etc. Compared with solid steel such as round steel, steel pipe is a kind of economic section steel because of its light weight and the same bending and torsional strength.

The steel type of thick steel plate is roughly the same as that of thin steel plate.

Steel tubes made of a single piece of metal with no seams on the surface are called seamless steel tubes. According to the production method, seamless pipe is divided into hot rolled pipe, cold rolled pipe, cold drawn pipe, extrusion pipe

Performance index of steel pipe

The mechanical property of steel is an important index to guarantee the final serviceability (mechanical property) of steel, which depends on the chemical composition and heat treatment system of steel. In the steel pipe standard, according to different use requirements, the tensile properties (tensile strength, yield strength or yield point, elongation) and hardness, toughness indicators, as well as user requirements of high, low temperature performance.

Profile is a solid straight strip with a certain section shape and size after plastic processing of metal.

Profile is a solid straight strip with a certain section shape and size after plastic processing of metal. There are many kinds and specifications of profiles and they are widely used and play a very important role in rolling production. Profiles are objects with certain geometric shapes made of iron or steel and materials with certain strength and toughness through rolling, extrusion, casting and other processes. This kind of material has a certain appearance size, a certain shape of the section, has a certain mechanical and physical properties. Profiles can be used alone or further processed into other manufactured products, often used in building structure and manufacturing installation. Mechanical engineers can choose the specific shape, material, heat treatment state, mechanical properties and other parameters according to the design requirements of the profile, and then according to the specific size and shape requirements of the profile for segmentation, and then further processing or heat treatment, to achieve the accuracy of the design requirements. The material and size of the profile can refer to the corresponding national standards.
