Product Description

GB/T 5310 12Cr2MoG High Pressure Seamless Boiler Tubes:

Product Description: GB/T 5310 12Cr2MoG High Pressure Seamless Boiler Tubes are specifically engineered for high-pressure boiler applications. These tubes are manufactured in accordance with the Chinese national standard GB/T 5310, which dictates the standards for seamless steel tubes suitable for high-temperature and high-pressure service. The 12Cr2MoG grade indicates an alloy steel with chromium (Cr) and molybdenum (Mo) additions, providing excellent heat resistance and creep strength, while the 'G' denotes its intended use for high-pressure purposes.

These tubes are seamless, ensuring a uniform material structure free from welds, which can be a source of weakness in lower quality tubing. The seamless construction also allows for better tolerance control and higher pressure ratings, making them ideal for critical boiler applications.

Product Applications:

  1. Power Plants: Widely used in power plants for steam generation, where high pressure and temperature are maintained.
  2. Industrial Boilers: Utilized in various industrial boilers for process heating, power generation, and other applications requiring high-pressure steam.
  3. Pressure Vessels: Suitable for the construction of pressure vessels and heat exchangers that operate under high thermal and pressure loads.
  4. Petrochemical Industry: Employed in the petrochemical sector for high-pressure piping and components in refineries and chemical plants.
  5. Nuclear Power Stations: Used in nuclear power stations for their ability to withstand the rigors of high radiation and pressure environments.

Key Features:

  • High-Pressure Capability: Designed to withstand the high pressures found in boiler systems.
  • Heat Resistance: Alloy composition provides resistance to high temperatures, reducing the risk of failure in thermal cycling.
  • Creep Strength: The addition of chromium and molybdenum enhances the creep strength, crucial for long-term performance under continuous load.
  • Seamless Design: Offers superior structural integrity and reliability compared to welded tubes.
