November 29, 2025
|

Steel pipes with a nominal diameter of 168 mm (often labeled as φ168 or Ø168.3 mm) play an essential role in many industrial and construction sectors. With exceptional strength, rigidity, and corrosion resistance, this pipe size has become a go-to option for systems requiring durability, pressure tolerance, and long-term structural reliability.

The following guide provides an all-new presentation of applications, technical information, and current price ranges for φ168 steel pipes.

1. Core Uses and Advantages of φ168 Steel Pipes

Manufacturers produce φ168 pipes using premium carbon steel or alloy steel that meets international standards such as JIS, ASTM, API, and TCVN. Their engineering characteristics make them suitable for demanding environments.

Key Advantages

  • High mechanical strength for heavy-load conditions
  • Long service life with excellent structural stability
  • Capable of handling high internal pressure
  • Strong corrosion resistance, especially in galvanized versions
  • Compatible with welding, cutting, and threading processes

Where φ168 Pipes Are Commonly Used

  • Fire protection systems (PCCC)
  • Water distribution and oil & gas pipelines
  • Factory frameworks and industrial steel structures
  • Civil engineering projects: bridges, culverts, foundation piles
  • Manufacturing of industrial machinery and components
  • Chemical handling, pressurized gas transfer, and storage systems

Depending on the project’s technical requirements, buyers may select from:

  • Standard black steel pipes
  • Hot-dip galvanized pipes
  • Welded pipes (ERW, HFIW)
  • Seamless pipes for high-pressure operations

2. Typical Technical Data for φ168 Steel Pipes

  • Outer diameter: Ø168.3 mm (standard)

Common Thickness and Length Options
