What are Boiler tubes?

Boiler tubes are seamless tubes and are made of either carbon steel or alloy steel. They are widely used in steam boilers, for power generation, in fossil fuel plants, industrial processing plants, electric power plants, etc.

Boiler tubes can either be medium-pressure boiler pipes or high-pressure boiler pipes. Boiler tubes are often manufactured in seamless procedures.

Boiler pipes refers to steel that is open at both ends and has a hollow section. Boiler and heat exchange tubes must be temperature and pressure resistant. For specific applications, they even need to increase or reduce heat transmission.

How to Choose Good Quality Boiler Tubes?
While choosing boiler tubes, look for the following to pick out the right and good quality tubes:

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. Make sure you check the trademark. Reputed manufacturers always put their trademark on their seamless tubes.

4. 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.
