Description

GB/T5310 20G High Pressure Alloy Seamless Boiler Tubes/Pipes

1. Product Description: GB/T5310 20G High Pressure Alloy Seamless Boiler Tubes/Pipes are designed for high-pressure boiler applications that require exceptional heat resistance and mechanical strength. These tubes and pipes are manufactured from an alloy steel that is seamless, ensuring uniform wall thickness and superior structural integrity. The 20G grade is specifically formulated to offer a balance of strength and ductility, making it suitable for high-temperature and high-pressure environments.

2. Product Parameters:

Parameter Description
Grade GB/T5310 20G
Material High Pressure Alloy Steel (Seamless)
Standard GB/T5310
Size Range Various diameters and wall thicknesses as per GB/T5310
Length Standard lengths, customizable upon request
Ends Plain ends, beveled ends, threaded, or socket-weld ends
Surface Treatment As-rolled, annealed, or normalized

3. Mechanical Properties:

Property Typical Requirements
Tensile Strength ≥415 MPa (60,000 psi)
Yield Strength ≥240 MPa (35,000 psi)
Elongation ≥20% in 50 mm (2 in) or 4D, whichever is greater
Hardness Varies depending on heat treatment

4. Chemical Composition:

Element Typical Range (%)
Carbon 0.17 - 0.24
Manganese ≤1.00
Phosphorus ≤0.025
Sulfur ≤0.025
Silicon ≤0.50

5. Product Applications:

  • Boiler Tubes: Used for steam generation in high-pressure boilers.
  • Superheater and Reheater Tubes: Employed in superheater and reheater sections of steam power plants.
  • Heat Exchangers: Suitable for use in heat exchangers operating under high pressure and temperature.
  • Pressure Vessels: Ideal for construction of high-pressure vessels and reactors in petrochemical and refining industries.

6. Product Advantages:

  • Seamless Construction: Provides a consistent material structure and eliminates potential seam-related failures.
  • High-Pressure Capability: Alloy steel offers excellent resistance to high pressures and temperatures.
  • Creep Resistance: Designed to resist deformation under prolonged exposure to heat, which is critical in boiler applications.
  • Weldability: The 20G grade has good weldability, making it easy to integrate into various systems.
  • Corrosion Resistance: Enhanced resistance to corrosion and oxidation due to the alloy content.
