Alloy Steel Pipe Introduction
Alloy steel pipe has a hollow cross section and is used in large quantities as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, alloy steel pipe is lighter in weight when the bending and torsional strengths are the same. Alloy steel pipe is an economical cross-sectional steel and is widely used in the manufacture of structural and mechanical parts, such as oil drilling rods, automobile drive shafts, bicycle frames and steel scaffolding used in construction. Alloy steel tube manufacturing ring-shaped parts, can improve material utilization, simplify the manufacturing process, saving materials and processing time, such as rolling bearing rings, jack sets, etc., has been widely used to manufacture steel pipe. Alloy steel tube or a variety of conventional weapons indispensable materials, gun barrels, barrels and other steel tubes to manufacture. Alloy steel tubes can be divided into round tubes and shaped tubes according to the different shapes of the cross-sectional area. Since the circular area is the largest under the condition of equal circumference, more fluid can be conveyed with circular tubes. In addition, the circular cross-section is more evenly stressed when subjected to internal or external radial pressure, therefore, the majority of steel pipes are round.
The biggest advantage of alloy steel pipe in English can be 100% recycled, in line with the national strategy of environmental protection, energy saving and resource conservation, and the national policy encourages the expansion of the application field of high pressure alloy pipe. At present, China's consumption of alloy pipe accounts for only half of the total steel in developed countries, the expansion of the use of alloy pipe field to provide a broader space for the development of the industry. According to the study of China Special Steel Association alloy pipe branch expert group, the future demand for high pressure alloy pipe long material in China can grow at an average annual rate of 10-12%. Alloy pipe is a steel pipe according to the production of materials (that is, materials) to define, as the name implies is the alloy made of pipe.
Applications
Alloy steel pipe is mainly used in power plants, nuclear power, high pressure boilers, high temperature superheaters and reheaters and other high pressure and high temperature pipelines and equipment, it is made of high quality carbon steel, alloy structural steel and stainless heat resistant steel, hot rolled (extruded, expanded) or cold rolled (drawn).
