Product Description

GB 5310 High pressure boiler tube

GB 5310 boiler tubes are high-quality, seamless steel tubes designed to withstand extreme conditions.

GB 5310 Seamless Pipe's main application is high pressure pipeline tube in boiler project (superheater tubes, reheater tubes, windpipe), it is featured with high strength and high resistance to corrosive conditions.

These boiler tubes are typically made from high-grade carbon and alloy steel. The specific composition may vary, but they are known for their exceptional resistance to high temperatures and pressures. This property makes them ideal for demanding applications.

Boiler Tubes in Power Generation

In the realm of power generation, GB 5310 boiler tubes are employed in various components, including:

Boilers: These tubes are a critical part of steam generators in power plants.
Superheaters: They contribute to the superheating of steam, increasing its energy content.
Economizers: Used to improve the overall efficiency of the boiler system.
Heat Exchangers: Play a vital role in transferring heat from combustion gases to water.

Industrial Applications

Beyond power generation, GB 5310 boiler tubes find utility in a wide range of industrial applications, including:

Oil Refineries: Used in processes requiring high-temperature heat transfer.
Chemical Processing: Critical for maintaining precise temperatures in chemical reactors.
Petrochemical Industry: Employed in heat exchangers for various applications.
Manufacturing: Utilized in industrial furnaces and heating systems.

GB 5310 boiler tubes are indispensable components in power generation, industrial heating, and numerous other applications. Their ability to withstand high temperatures and pressures, coupled with efficient heat transfer properties, makes them a preferred choice for industries where reliable heat exchange is paramount.

15CrMoG alloy pipe

15CrMoG is a type of heat-resistant steel that is often used in boilers and piping systems. The name "15CrMoG" refers to the chemical composition of the steel, which is 15% chromium and molybdenum.

Alloy Steel Pipe

GB 5310 is a standard for seamless tubes used in high-pressure steam boilers and pipelines. The main application for GB 5310 tubes is as high-pressure pipeline tubes in boiler projects. These tubes can be used for superheaters, reheaters, and windpipes.

The GB 5310 standard applies to tubes made from materials such as:

10#, 20#, 45#
15Mn, 20Mn, 45Mn
30Mn2, 20Mn2, 15CrMoG
12Cr1Mo1VG, 12CrMoG

The long-term use temperature for GB 5310 20G seamless steel pipes used as headers and steam pipes is ≤ 425 ° C.
