Description

Sch40 GB/T3087 20 Grade Alloy Seamless Boiler Pipe: A High-Performance Option for Boiler Applications

1. Product Description: Sch40 GB/T3087 20 Grade Alloy Seamless Boiler Pipes are engineered to meet the demands of high-pressure and high-temperature boiler systems. These pipes are manufactured from alloy steel and are seamless, providing a uniform wall thickness and ensuring excellent structural integrity. The 'Sch40' denotes the standard weight and dimensions according to ASME B36.10, while GB/T3087 is the Chinese national standard that specifies the requirements for these alloy steel pipes.

2. Product Parameters:

Parameter Description

Material Alloy Steel (Seamless)
Standard GB/T3087, ASME B36.10
Schedule Sch40
Size Range Various diameters and wall thicknesses as per GB/T3087
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 Requirement
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 and processing

4. Chemical Composition:

Element Typical Range (%)
Carbon 0.17 - 0.24
Manganese 0.35 - 0.65
Silicon 0.17 - 0.37
Chromium ≤ 0.030
Copper ≤ 0.030

5. Product Uses:

  • Boiler Tubes: Used in power and industrial boilers for steam generation.
  • Superheater Tubes: Employed in the superheater 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.

6. Product Grade Standards:

  • GB/T3087: This Chinese national standard specifies the requirements for alloy steel pipes intended for high-temperature and high-pressure boiler and superheater applications.
  • ASME B36.10: This standard covers the dimensions and weights of seamless钢管 (pipes), including Sch40.
