Mechanical Properties

The mechanical properties of GB/T 31940 bi-metal composite corrosion resistance steel pipe are as follows:

Property Value
Tensile Strength (MPa) ≥ 560
Yield Strength (MPa) ≥ 390
Elongation (%) ≥ 22
Impact Toughness (J/cm²) ≥ 45
Hardness (HB) ≤ 250

Steel Grade and Application

The GB/T 31940 standard specifies different steel grades for bi-metal composite corrosion resistance steel pipes. These grades are suitable for various fluid transportation applications, including but not limited to:

  • Oil and gas industry
  • Water treatment plants
  • Chemical processing plants
  • Power generation facilities

Possible Alternative Grades

While GB/T 31940 bi-metal composite corrosion resistance steel pipe is a highly specialized material, there are some possible alternative grades that may be considered for specific applications. These include:

  1. Stainless Steel: Offers excellent corrosion resistance, but may be more expensive.
  2. Polymer-Coated Steel: Provides corrosion protection with a lightweight and flexible solution, suitable for certain application conditions.
  3. Fiberglass-Reinforced Plastic (FRP): Offers exceptional corrosion resistance with excellent strength-to-weight ratio, commonly used in the chemical industry.

It is important to carefully evaluate the specific requirements of each application before selecting an alternative grade to ensure compatibility and optimum performance.
