Seamless Boiler Tubes
Boiler tubes are used in heat exchange appliances in which the energy is transferred from one medium to the other.
How to choose good quality boiler tubes?
While choosing boiler tubes, look for the following to pick out the right and good quality tubes:
- 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.
- Check the density of the pipe to understand the percentage of impurities in the pipe. If the pipe shows low density, steer clear!
- 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.
We have capability and capacity to ensure boiler tube in superior condition, with advanced inspection and testing procedures, standard tests include dimensional examination, visual checking, chemical composition, mechanical properties as well as non destructive test 100% eddy current test.
Fire Tube Boiler
Fire-tube boiler is a type of boiler in which hot gas passes from the fire through one or more pipes that pass through a sealed water container. The heat of the gas is transferred through the wall of the tube through heat conduction, heating the water and eventually generating steam. Fire tube boilers are the third of the four historical types of boilers: low-pressure tank or “haystack” boilers, flue boilers with one or two large flues, fire tube boilers and high-pressure boilers with many small tubes
Water Tube Boiler
Water tube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. The fuel is burned in the furnace to produce hot gas, which heats the water in the steam generation tube. In smaller boilers, the additional power generation tubes are separated in the furnace, while larger utility boilers rely on water injection tubes that make up the furnace wall to generate steam. High-pressure water tube boiler: The hot water then rises into the steam drum. Here, saturated steam is drawn away from the top of the drum
North Steel has an extensive range of boiler and stay tubes available to meet your boiler tube requirements no matter how demanding.
