The production process of seamless steel pipe
2023-10-11
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
2023-07-12
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
2022-10-30
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. 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.
Corrosion resistance of welded steel tubes
2022-07-13
In the production of T-welded steel pipe, the wrong edge often occurs, and there are many influencing factors. In production practice, steel pipe is often degraded by the wrong edge. Therefore, it is necessary to analyze the causes of spiral steel pipe misalignment and its preventive measures.
What are the welding methods of steel pipe classification
2022-04-21
According to different welding methods, it can be divided into arc welding pipe, high frequency or low frequency resistance welding pipe, gas welding pipe, furnace welding pipe, Bondi pipe, etc.
Stainless steel pipe according to the material divided into what
2022-02-15
Stainless steel pipe according to the production method is divided into seamless pipe and welded pipe two categories, seamless steel pipe can also be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and extrusion pipe, cold drawing, cold rolling is the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.
