Application of Seamless Steel Pipe

Oil and gas industry

The oil and gas industry requires a large number of seamless steel pipes to transport and transport oil, natural gas, and other liquids or gases. These pipelines must be able to withstand high pressure and high temperature conditions while maintaining stable and reliable transportation. Seamless steel pipes are widely used in this industry due to their high strength and corrosion resistance.

Chemical industry

Many processes in the chemical industry require the use of corrosion-resistant pipelines to transport various chemicals. Seamless steel pipes have become an ideal choice for the chemical industry due to their corrosion resistance and high-temperature stability. They can work in harsh chemical environments and can withstand high pressure and temperature.

Electric power industry

Seamless steel pipes are widely used in power plants and transmission lines in the power industry. The power plant uses seamless steel pipes to transport steam and cooling water. The steel pipe tower structure in transmission lines also requires seamless steel pipes as support and conductor channels.

Construction engineering

In construction engineering, seamless steel pipes are often used in building frames, support structures, and drainage systems. Due to the high strength and stability of seamless steel pipes, they can withstand a large amount of weight and pressure while providing structural stability.

Automobile manufacturing industry

The automotive manufacturing industry requires a large amount of seamless steel pipes for manufacturing engine and chassis components. Seamless steel pipes can withstand high temperature and high pressure conditions, and have excellent mechanical properties, suitable for the high requirements of automotive engines.

Aerospace industry

In the aerospace industry, seamless steel pipes are widely used in aircraft structures, engines, and fuel systems. Due to its lightweight and high-strength characteristics, seamless steel pipes help improve the fuel efficiency and flight safety of aircraft.

Production Method Of Seamless Steel Pipe

Hot Rolling

Heating: The billet is preheated through the heating furnace.
Perforation: The heated steel billet is perforated through a perforation machine.
Rolling: The perforated tube blank is rolled multiple times to adjust diameter and wall thickness.

Cold Drawing:

Hot rolling: After hot rolling, the steel billet forms an initial tubular structure.
Cold drawing: The hot-rolled tube blank is mechanically stretched through cold drawing.

Extrusion:

Heating: The billet is raised to extrusion temperature through a heating furnace.
Extrusion: The heated billet is extruded through an extruder to form a tubular structure.

Rotary Piercing

Heating: The steel billet is raised to the rotary extrusion temperature.
Rotary extrusion: The heated steel billet is rotary extruded to form a tubular structure.

Hollow Tube Piercing

Heating: The steel billet is raised to the piercing temperature.
Perforation: The heated steel billet is perforated through a perforation machine.

Shipping and Payment Terms

Payment terms	30% T/T deposit and 70% on B/L copy or L/C at sight, before you pay the balance.
Shipping	It can be delivered by truck, train, sea .

FAQ

Q: What is the difference between seamless and non seamless tube?

A: Seamless tubing can contain higher pressure because it does not have the large stress concentration point that welded tubing has. Additionally, seamless tubing often has a cleaner surface finish meaning it is less susceptible to pitting and corrosion.

Q: What are the manufacturing tolerances for seamless pipe?

A: For the M series welded pipe of the standard, the Wall Thickness Tolerance is ± 10%, while for the seamless pipe of this M series of the standard, the tolerance is ± 12.5%. In the case of welded pipe, the longitudinal weld bead must be ground to a smooth surface finish.

Q: What is the absolute roughness of seamless pipe?

A: The roughness of a pipe is normally specified in either mm or inches and common values range from 0.0015 mm for PVC pipes through to 3.0 mm for rough concrete pipes.

Q: What is the density of seamless steel pipe?

A: The steel used for seamless steel pipes generally has a density of 7.85 kg/dm3. Seamless steel tubes have hollow sections and are used in large quantities as pipes for transporting fluids, such as pipes for transporting petroleum, natural gas, gas, water and certain solid materials.
