Characteristics and applications of hot-rolled seamless tubes

Characteristics and applications of hot-rolled seamless tubes:

1) Characteristics of hot-rolled seamless steel tube

Heat-rolling technology is used to create hot-rolled seamless steel pipes, which have the following properties:

1. High strength: The seamless hot-rolled tube undergoes several cold drawing, cold rolling, and final rolling procedures. It can sustain higher pressures and has a strength that is two to three times that of regular steel pipes.

2. High precision: The hot-rolled seamless tube is less likely to experience quality issues because of its smooth inner and outer surfaces, high diameter accuracy, and uniform wall thickness.

3. High pressure resistance: Compared to welded pipes, hot-rolled seamless tubes are more resilient and do not readily twist or deform in high-temperature and high-pressure settings.

2) Application of hot-rolled seamless steel tube

Hot-rolled seamless steel tubes find extensive application in various fields such as the petroleum, chemical, aviation, aerospace, and machinery manufacturing industries.

1. Petroleum field: Oil well riser pipes, oil pipes, oil casings and casings, etc. can all be made from hot-rolled seamless steel tubes. They are able to tolerate higher oil pressure as well as the oil circuit’s high temperature and high pressure environment.
2. Chemical industry: Chemical pipelines, furnace tubes, storage tanks, and other structures can all benefit from the use of hot-rolled seamless steel tubes. has a strong resistance to corrosion.

3. Aviation and aerospace industries: Engines and tires are among the components that are frequently made in these industries using hot-rolled seamless steel tubes.

4. The manufacturing of machinery: Hot-rolled seamless steel tubes can also be utilized as transmission shafts, hydraulic pipes, and other machine parts. Owing to its exceptional strength, precision, and resistance to pressure, it can significantly extend the lifespan and operational efficiency of machinery and equipment.

The features and uses of hot-rolled seamless tubes are listed above. It is evident that there are many potential applications for hot-rolled seamless steel tubes across a range of industries. Welded pipes cannot match their performance and quality, but they are more expensive and require more complex processing.
