Boiler tubes are a type of steel tubes, and boiler tubes are generally made of seamless tubes. Boiler tubes are pipes used to transport high-temperature and high-pressure fluids. They are commonly used in equipment such as industrial boilers, heat exchangers, and power stations. Boiler tubes have the characteristics of high temperature resistance, high pressure resistance, corrosion resistance, etc., and are one of the most important components of these equipments.
Boiler tubes are usually made of carbon steel, alloy steel, stainless steel and other metal materials. Their quality and performance directly affect the safe operation and energy efficiency of the boiler.
Size:
Out diameter (OD) 10.2 - 139.7 mm (from 26.9 mm manufactured as hot rolled)
Wall thickness (WT) 0.5 - 16.0 mm (from 2.6 mm manufactured as hot rolled)
ASTM A 210 – A&C | Specification for Seamless Medium-Carbon Steel Boiler and Superheater Tubes |
ASTM A 213 - T-5, T-9, T-11, T-22, T-91 | Specification for Seamless Alloy-Steel Boiler, Superheater and Heat Exchanger Tubes |
How to choose the right boiler tube?
1. Look at the cross-section of the tube. A good quality seamless tube will have a smooth cross-section and will be devoid of bumps and irregularities.
2. Check the density of the pipe to understand the percentage of impurities in the pipe. If the pipe shows low density, steer clear!
3. Check the surface of the boiler tube. A good quality boiler tube will have a smooth surface. If you find the surface to be rough and uneven, you can be sure that the quality is not up to the mark.
