What Types of Steel Pipes Are There According to Their Use?

Understanding Steel Pipe

Compared to solid steel materials such as round steel, structural steel pipe is lighter in weight while maintaining the same bending and torsion strength. This makes them an economical steel material commonly used to manufacture structural components and mechanical parts such as drill pipes, drive shafts for automobiles, machine frames, and scaffolding for construction. Using steel and pipe to manufacture circular components can reduce the weight of the parts, increase material utilization, simplify manufacturing processes, save materials and machining time, and are widely used in the production of rolling bearing bushings, jack sleeves, and other components. Steel pipes are also an essential material for all kinds of conventional weapons, such as gun barrels and cannon tubes.

Steel and pipe is not only used for transporting fluids and powders, exchanging heat, and manufacturing mechanical parts and containers, but it is also an economical steel material. Using steel and pipe to manufacture building structure grids, pillars, and mechanical supports can reduce weight, save 20-40% of metal materials, and achieve factory-based and mechanized construction.

Categorized by application

  • Steel pipe for Pipeline Use: Such as water, gas pipes, carbon steel seamless steel pipe for steam pipelines, oil transport pipes, and petroleum gas pipelines, water tap pipes for agricultural irrigation and sprinkler pipes.

  • Steel pipe for Thermal Equipment: Such as boiling water pipes and superheated steam pipes for general boilers, superheated pipes, large and small smoke pipes, arch brick pipes, and high-temperature and high-pressure boiler pipes for locomotive boilers.

  • Steel pipe for Petroleum Geology Drilling: Such as oil drilling pipes, oil drill rods (square drill rods and hexagonal drill rods), drill pipes, oil pipes, oil casings, various pipe joints, and geological drilling pipes (core pipes, casings, active drill rods, drill rods, buckle rings, and pin joint).

  • Steel pipe for Chemical Industry: Such as pipes for petroleum cracking, pipes for chemical equipment heat exchangers and pipelines, stainless acid-resistant pipes, high-pressure pipes for fertilizers, and pipes for conveying chemical media.

  • Steel pipe for other departments: Such as container pipes (pipes for high-pressure gas cylinders and general container pipes), pipes for instruments, pipes for watch cases, pipes for injection needle and medical devices.
