What are the options for boiler tube materials?

Date:2024-07-15

Boiler tubes are essential components used to transport hot water or steam, and the choice of material significantly impacts their performance and service life. Here are some common materials used for boiler tubes.

 

- Carbon Steel: Widely used for its good mechanical properties and high temperature resistance. Common types include 20#, 20G, and ASTM A106 Gr.B.

- Low Alloy Steel: Offers better heat and pressure resistance than carbon steel. Examples include 12CrMoG, 15CrMoG, and 12Cr1MoVG.

- Stainless Steel: Known for high corrosion and temperature resistance, making it suitable for high-temperature and high-pressure environments. Common grades include 304, 316, and TP316L.

- Copper Alloy: Typically used in low-temperature, low-pressure boiler systems due to its good thermal conductivity and corrosion resistance. Examples include C44300 and C68700.

- Aluminum Alloy: Used in lightweight boiler systems, offering excellent thermal conductivity and corrosion resistance. Common types include 6061 and 6063.

- Titanium Alloy: Provides good corrosion resistance and high temperature strength, suitable for special working conditions. Examples include TA1 and TA2.

 

Types of Boiler Heating Surface Pipes:

Depending on the boiler type and operating conditions, different materials are chosen for boiler heating surface pipes. Here are their characteristics:

- Carbon Steel Pipe: Economical, high strength, good toughness, and easy to process and weld. However, it is highly susceptible to corrosion and has a relatively short service life.

- Chromium Alloy Steel Pipe: Contains chromium and other elements, offering high temperature resistance, oxidation resistance, and corrosion resistance. Ideal for high-temperature, high-pressure, and highly corrosive environments.

- Stainless Steel Pipe: Increasingly used due to excellent corrosion resistance, heat resistance, and high strength. Generally suitable for high-end boiler equipment due to its higher cost.

- Nickel-Based Alloy Tube: Made from nickel or nickel alloys, these pipes offer exceptional corrosion resistance, high temperature strength, and are suitable for harsh environments.

 

Principles for Selecting Boiler Heating Surface Pipes:

Usage Conditions: Choose materials based on specific working conditions.

Mutual Coordination: Ensure the selected pipes enhance the coordination and cooperation between various boiler components.

Economic Reasonability: Select cost-effective materials that meet performance requirements.

 

In summary, selecting the appropriate boiler heating surface pipes can significantly enhance the boiler's performance and lifespan while preventing failures and accidents. Contact us to learn more about how our materials can meet your boiler tube needs.
