What is seamless steel pipes

Seamless steel pipe is a type of pipe that is made from a single, round bar of steel.
The bar is heated, and a probe is used to create a hole through the cylinder. The cylinder is then rolled to the desired diameter and wall thickness.
Seamless steel pipe has no seams, joints, or welds on its exterior.

Seamless steel pipes have the following specifications: 

  • Diameter: 114-914 mm
  • Thickness: 4-60 mm
  • Length: According to your requirements
  • OD: 6-710 mm
  • WT: 0.6-48 mm
  • Length: 5.8/6/11.8/12m

The most common specification for seamless carbon steel pipe is A106B. The most common specification for stainless steel pipe is A312. Stainless steel pipes can withstand high temperatures and corrosive environments. 

Seamless steel pipes have the following characteristics: 

  • High precision
  • Smaller diameter
  • Strong weldability
  • High compression capability
  • Good surface quality
Seamless steel pipes are also known as mild steel pipes and tubes. They are low-cost and easy to form and shape. 

Seamless steel pipe is more resistant to corrosion and can withstand higher pressures than welded pipe. However, welded pipe is generally less expensive because it is a simpler process. When buying pipes, you can consider factors such as:
Quality of materials
Corrosion resistance
Tensile strength
Ease of use
