The seamless steel pipe is made by perforating the whole round steel, and the steel pipe without weld seam on the surface is called seamless steel pipe. Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.
The main advantages of seamless steel pipe 1. Seamless steel pipe has the advantage of being strong and durable. Seamless steel pipes are steel pipes, which are impact-resistant, abrasion-resistant, and corrosion-resistant. They have a long service life and have a permanent effect (in comparison). It can meet the needs of various laying.
2. Seamless steel pipe has the advantage of high temperature resistance. Ordinary carbon steel can withstand a temperature of 350°C. If special alloying elements such as chromium, nickel, tungsten, and titanium are added in production, the seamless steel pipe can withstand a high temperature of about 600°C, which improves its unique use.
3. Seamless steel pipe has the advantage of high pressure resistance. Seamless steel pipes have excellent mechanical properties. Ordinary seamless carbon steel pipes can withstand pressure from 1.6MPa to 6.4MPa. If special alloying elements are added during production, the pressure resistance can reach ultra-high pressure to meet the needs of special production processes. This is one of its most important advantages over cast iron pipes, copper pipes, aluminum pipes, and various non-metallic pipes.
4. Solderability advantage. Seamless steel pipe has excellent weldability, which is convenient for lengthening butt joints, plugging, etc., but cast iron pipes and reinforced concrete pipes are difficult to compare with it.
5. The inner surface of the seamless steel pipe is smooth, and the conveying resistance is very small.
6. Seamless steel pipe is resistant to high temperature, high pressure, mechanical stamping, small resistance, and good connection lengthening. Therefore, it is the best material for long-distance fluid transportation.
