Thick-walled seamless steel pipes are widely used in the industrial field due to their unique properties, such as high strength, high pressure bearing capacity and good corrosion resistance. Nansteel Manufacturing Co., Ltd carefully summarizes the main uses of thick-walled seamless steel pipes in industry:
1. Oil and Gas Industry
Transportation pipelines: Long-distance high-pressure pipelines used to transport crude oil, natural gas, refined oil and other media, especially in harsh environments such as the seabed, desert, and high-cold areas. Thick-walled seamless steel pipes can withstand high pressure and complex external environments.
Casing and tubing: In the process of oil and gas extraction, casing and tubing are used to support the well wall and transport oil and gas to the ground. They need to withstand the high pressure of the formation and the erosion of corrosive media. Thick-walled seamless steel pipes are an ideal choice.
Drilling equipment: Used to manufacture key components of drilling equipment such as drill pipes and drill collars, which need to withstand high torque, high pressure and impact loads.
2. Chemical Industry
High-pressure containers and pipelines: Used to manufacture various high-pressure reactors, heat exchangers, storage tanks and other equipment, as well as pipelines for conveying corrosive media. Thick-walled seamless steel pipes can withstand high temperature, high pressure and corrosion from various chemical media.
Fertilizer equipment: High-pressure equipment and pipelines used in the fertilizer production process, such as synthesis towers, conversion furnaces, etc.
3. Power industry
Boiler pipes: Used to manufacture water-cooled wall tubes, superheater tubes, reheater tubes, etc. in power station boilers, which need to withstand high temperature, high pressure and high-temperature steam erosion.
Nuclear power industry: Used in key components such as pressure vessels and pipelines in nuclear reactors, which have extremely high requirements on material safety and reliability.
Bearing rings: Bearing rings used in the manufacture of heavy machinery, vehicles, etc., need to have high strength, high hardness and wear resistance.
Structural parts: Structural parts used to manufacture various mechanical equipment, such as machine tool beds, crane booms, etc.
5. Construction
Large building structures: Steel structures used in large bridges, stadiums, airport terminals, etc., providing strong support and stability.
Marine engineering: Used in marine engineering such as offshore platforms and submarine pipelines, which need to withstand the corrosion and wave impact of the marine environment.
6. Other industrial fields
Aerospace: Used to manufacture key components such as aircraft landing gear and rocket engine casings, which require high strength, light weight and high temperature resistance.
Automobile Industry: Used to manufacture automobile chassis, axles and other components to improve the strength and safety of vehicles.
Metallurgical Industry: Pipes and structural parts used for metallurgical equipment.
When selecting thick-walled seamless steel pipes, the following factors need to be considered:
1. Working pressure: Select the appropriate wall thickness according to the pressure the pipe or container is subjected to.
2. Working temperature: Choose appropriate material according to the working temperature to ensure that the steel pipe has good performance in high or low temperature environment.
3. Medium characteristics: Select appropriate materials according to the corrosiveness of the conveying medium, such as stainless steel, alloy steel, etc.
4. Use environment: Select appropriate anti-corrosion measures according to the use environment, such as coating, galvanizing, etc.
5. Standard requirements: Must comply with relevant national standards or industry standards.
