15CrMoG high-pressure alloy tube

15CrMoG High-Pressure Alloy Tube

Product Overview:
15CrMoG is a chromium-molybdenum alloy steel tube designed for high-pressure and high-temperature applications, especially in power plants and petrochemical industries. It is manufactured in accordance with Chinese standards such as GB/T 5310 and is widely used in boilers, pressure vessels, and heat exchangers where excellent strength, creep resistance, and toughness are essential.

Mechanical Properties:
The 15CrMoG alloy tube offers high yield strength and tensile strength, capable of withstanding elevated temperatures and pressures for long-term service. Its chemical composition, enriched with chromium and molybdenum, improves hardenability, corrosion resistance, and overall mechanical performance. The tube also maintains good weldability, facilitating its use in complex pressure piping systems.

Manufacturing and Sizes:
Produced mainly through seamless hot rolling or cold drawing processes, 15CrMoG tubes feature precise dimensional control and smooth surface finish. They are available in various outer diameters and wall thicknesses to meet specific engineering demands, with customizable lengths for diverse industrial applications.

Advantages:

• High strength and excellent creep resistance under elevated temperature and pressure

• Superior corrosion and oxidation resistance due to chromium content

• Good weldability and machinability for fabrication and assembly

• Reliable dimensional accuracy and surface quality

• Suitable for critical pressure piping and high-temperature components

Applications:
15CrMoG tubes are commonly applied in the construction of superheaters, reheaters, high-pressure boilers, petrochemical reactors, and power plant piping systems. They are also used in industries where tubes must endure harsh environments including thermal cycling and mechanical stress.

Quality Assurance:
Strict quality control procedures include non-destructive testing, hydrostatic pressure testing, chemical composition analysis, and mechanical property verification. Mill test certificates and third-party inspection services are provided to guarantee compliance with industry standards and customer requirements.
