High-pressure boiler tubes need to be selected from materials that are suitable for high temperatures, high pressures and corrosive environments to ensure their safety and reliability. The following are some of the common material options used for high pressure boiler tubes:

CarbonSteel: Low or medium carbon steel is widely used in some low and medium pressure boilers. The main advantages of carbon steel tubing are lower cost and ease of processing, but corrosion and oxidation may occur at high temperatures and pressures.

Alloy Steel (AlloySteel): Alloy steel has high strength and heat resistance and is suitable for use in high temperature and high pressure boilers. Commonly used alloying elements include chromium, molybdenum and cobalt, which provide oxidation and corrosion resistance.

StainlessSteel: Stainless steel is a steel with excellent corrosion resistance and is suitable for use in boiler environments requiring a high degree of corrosion resistance, such as in the chemical and food processing industries.

Chromium-Molybdenum Steel: Chromium-Molybdenum Steel is an alloy steel, usually containing chromium and molybdenum, with excellent high temperature strength and corrosion resistance, commonly used in high temperature and high pressure boilers.

NickelAlloys: Nickel alloys have high temperature and corrosion resistance, and are suitable for use in high-temperature and high-pressure boilers, such as in nuclear power plants.

TitaniumAlloys: Titanium alloys are used for high pressure boilers in some special applications due to their corrosion resistance and light weight properties.

Graphite: Graphite materials are often used in boilers for special chemical processes to withstand high temperatures and corrosion.

CompositeMaterials: Some advanced composite materials can be used in high temperature and high pressure boilers, with lightweight, high strength and corrosion resistance.

The choice of material depends on the specific application of the boiler, operating conditions and budget. High-pressure boiler tube manufacturers usually need to follow relevant standards and regulations to ensure that the selected materials meet safety and performance requirements. In addition, boiler tubes should be designed, manufactured and maintained in strict accordance with relevant codes and regulations to ensure their safe and reliable operation.
