Alloy Steel Tube Description:
The main purpose of alloy steel pipe is to be used in high pressure and high temperature pipelines and equipments such as power plants, nuclear power, high pressure boilers, high temperature superheaters and reheaters. It is made of high quality carbon steel, alloy structural steel and stainless heat-resistant steel. , Hot rolled (extruded, expanded) or cold rolled (pulled).
The biggest advantages of alloy steel pipe:
It can be recycled 100%, conforms to the national strategy of environmental protection, energy conservation and resource conservation. The national policy encourages the expansion of the application of high-pressure alloy pipes. At present, the consumption of alloy pipes in China accounts for only half of the total amount of steel. The use of alloy pipes has expanded to provide a broader space for the development of the industry. According to the study of the expert group of the China Special Steel Association's alloy pipe branch, the average annual growth of high-pressure alloy pipe long products in China will reach 10-12%.
The difference between alloy tube and seamless tube is as follows:
The alloy pipe is defined according to the production material (that is, the material). The tube is defined by the alloy as its name implies; and the seamless pipe is defined according to the production process (seamless seam), which is different from the seamless pipe. Sewed pipe, including straight seam welded pipe and spiral pipe.
The material of the alloy tube is roughly: 16-50Mn, 27SiMn, 40Cr, 12-42CrMo 16Mn 12Cr1MoV T91 27SiMn 30CrMo 15CrMo 20G Cr9Mo 10CrMo910 15Mo3 15CrMoV 35CrMoV 45CrMo, 15CrMoG, 12CrMoV, 45Cr, 50Cr, 45CrNiMo, and the like.
Alloy tube standard:
The alloy tube has a hollow cross-section and is used in a large amount as a conduit for transporting fluids, such as pipelines for transporting oil, natural gas, coal gas, water, and certain solid materials. Compared with solid steel such as round steel, alloy steel pipes have a lighter weight under the same bending and torsional strength. Alloy steel pipes are economical cross-section steels and are widely used to manufacture structural parts and mechanical parts such as oil drill pipes and automobile transmissions. Shafts, bicycle racks, and steel scaffolds used in construction. The use of alloy steel pipes () to make ring-shaped parts can increase material utilization, simplify manufacturing processes, save materials and processing man-hours, such as rolling bearing rings, jack sleeves, etc., which are now widely used in steel pipes. The alloy steel pipe is also an indispensable material for various conventional weapons. The barrels, barrels, etc. must be made of steel pipes. Alloy steel pipe can be divided into round pipe and shaped pipe according to different cross-sectional shape. Since the circle area is the largest under the condition of the same circumference, more fluid can be transported by the circular tube. In addition, when the ring section is subjected to internal or external radial pressure, the force is more uniform. Therefore, most steel pipes are round pipes.
Alloy steel pipe weight calculation formula:
[(Outer Diameter - Wall Thickness) * Wall Thickness] * 0.02466 = kg/meter (weight per meter)
Alloy steel pipe theoretical weight calculation formula:
(OD - wall thickness) × wall thickness × 0.02486 = KG/M
