API-5L welded spiral steel pipe is made of hot rolled strip steel or steel plate as raw material. The strip steel or steel plate is rolled into round or shaped steel pipe by forming machine, and then the formed steel pipe is butt welded by high-frequency welding unit. This kind of steel pipe has the advantages of high strength, high toughness, corrosion resistance, easy welding, etc., and is widely used in oil, natural gas, water and other fluid transportation fields.
Products Description
It is widely use in many fields like the following:
First of all, spiral steel pipe has been widely used in the field of oil and natural gas transmission. Spiral steel pipe has the characteristics of high strength, good corrosion resistance and light weight, and can be used for long-distance transportation of oil, natural gas and other media. Spiral steel pipes usually use high-frequency welding technology, so that the surface of the steel pipe can obtain good smoothness, while improving the strength and corrosion resistance of the steel pipe.
Secondly, spiral steel pipes are also widely used in the chemical industry. Spiral steel pipes can be used to manufacture a variety of high-pressure vessels and pipes to facilitate the transmission of corrosive liquids and gases. Spiral steel pipe has excellent resistance to acid, alkali, salt and other chemical media corrosion performance, can be used to manufacture a variety of high-end chemical equipment.
In addition, spiral steel pipe has also been widely used in the field of urban construction. For example, in pipeline construction, spiral steel pipes can be used to manufacture urban water supply pipes, drainage pipes, sewage treatment pipes, etc. Spiral steel pipe not only has high corrosion resistance, but also strong and durable, can be used for a long time.
In summary, spiral steel pipe has been widely used in various fields, its high strength, good corrosion resistance and lightweight characteristics, making it an important material in modern industry. The manufacturing process of spiral steel pipe is relatively simple and the cost is low, so it is widely0 used.
API 5L Spiral Welded Steel Pipe Features:
The characteristics of API 5L spiral welded steel pipe include biaxial symmetry, section centroid and shear centroid coincidence. The moment of inertia of the section is the same for each axis, whether it is a round tube or a square tube section, which makes its advantages as a bending and compression member very prominent.
The section of API 5L spiral welded steel pipe is closed, the torsional stiffness is large, and the local stability of the plate is good. In particular, the circular tube section, the polar axis of the section is evenly distributed, and the resistance to torque is particularly effective.
Inaddition, compared with ordinary open section steel, round tube and square (rectangular) section have the characteristics of flat surface, no dead Angle and small surface area, which is conducive to saving anti-corrosion and fireproof paint and easy to remove dust.
At the same time, its wind resistance coefficient is small, and it has significant advantages when exposed to fluids (such as wind and water flow).
