What is the Material of the Boiler Tube?

What is the material of the boiler tube? The boiler pipes refer to the pressure pipes used to make boilers. The main materials are generally divided into three categories: carbon steel, alloy steel and stainless steel. Among them, the materials commonly used in thermal power stations are 20G, 12CrMoV, 15CrMo and so on. These materials have good high temperature resistance, high pressure resistance, oxidation resistance and corrosion resistance, which can meet the requirements of the boiler in long-term operation.

In addition to the commonly used carbon steel, alloy steel and stainless steel, other materials are used to make boiler tubes according to different working conditions and requirements. For example, in some cases of high temperature and high pressure, it is necessary to use high-temperature alloy steel (such as P91, P92, etc.); in oxidizing environment, it is necessary to use oxidation-resistant alloy steel (such as 310S, 253MA, etc.); Under the need to use low temperature steel (such as LTCS, LC1, LC2, etc.) and so on. In short, the selection of materials should be determined according to actual needs and specific working conditions.

The diameter and wall thickness of boiler tubes also vary according to different conditions of use. Generally, the larger the diameter, the thinner the wall thickness will be; conversely, the smaller the diameter, the thicker the wall thickness will need to be. This is mainly to ensure the stability and durability of the boiler tube under high temperature and high pressure.

In addition, when selecting boiler tubes, factors such as pipeline layout and installation method also need to be considered. For example, some boiler tubes need to be bent or connected for use, so issues such as the bending radius of the tubes and the strength of the joints need to be considered. At the same time, it is also necessary to consider the stress of the pipeline and the thermal expansion and contraction during heating and cooling, so as to ensure the safe and reliable operation of the boiler tube.

In short, selecting the appropriate material, diameter, wall thickness and other parameters is a very important part of the boiler tube design process, and various factors need to be fully considered to ensure the safe and efficient operation of the boiler.
