Hot rolled seamless steel pipes are widely used in many industrial fields due to their good mechanical properties, high pressure bearing capacity and relatively low cost. Nansteel Manufacturing Co., Ltd has carefully summarized the major industries where hot rolled seamless steel pipes are most widely used:
1. Oil and Gas Industry
Transportation pipeline: Trunk pipelines and branch pipelines used for long-distance transportation of crude oil, natural gas, refined oil and other media. Since oil and gas transportation often needs to withstand high pressure and complex environmental conditions, the strength and reliability of hot-rolled seamless steel pipes are crucial.
Oil drilling: Used to manufacture key components of drilling equipment such as drill pipes, casing, and oil pipes. These components need to work in high temperature, high pressure, and corrosive environments underground. The pressure resistance and corrosion resistance of hot-rolled seamless steel pipes are key.
Oil refining and chemical equipment: used to manufacture various pressure vessels, heat exchangers, reactors and other equipment, which usually need to withstand high temperature, high pressure and corrosive media. The high temperature strength and corrosion resistance of hot-rolled seamless steel pipes make them an ideal choice.
Chemical equipment: used to manufacture chemical equipment such as reactors, storage tanks, heat exchangers, etc. These equipment usually need to withstand high temperature, high pressure and corrosive media. The performance of hot-rolled seamless steel pipes meets these stringent requirements.
3. Power industry
Boiler: Used to manufacture key components such as water-cooled wall tubes, superheater tubes, and reheater tubes for power station boilers. These components need to operate for a long time under high temperature and high pressure environments. The high temperature strength and creep resistance of hot-rolled seamless steel pipes are crucial.
Power station construction: used for structural support, pipe supports, etc. in power stations.
Bearing rings: The rings of some bearings are also made of hot-rolled seamless steel pipes.
Automobile and tractor parts: such as drive shafts, half shafts, steering shafts, etc.
Construction machinery: such as structural parts of cranes, excavators, bulldozers, etc.
Pile foundation engineering: Pile foundations used for buildings and bridges.
