ERW steel tube supplier West MidlandsOne place where you can find steel tubing would be as part of a boiler system. At some stage, you may have repaired a boiler tube leak only to find yourself confronted by another one shortly after. Pinpointing and rectifying the cause of tube malfunctions is critical to help minimise the likelihood of future issues. Tube failures typically occur due to other problems. To properly comprehend the reason for failure, you need to inspect all the elements. The following are some of the most common causes.

Caustic attack

The combination of water, boiler chemicals and a high temperature can result in caustic conditions within a pipe. If it builds up to a high concentration it can reach a high enough pH where it will dissolve the magnetite layer of the steel. Once this is gone it will allow corrosion and cause a failure.

Oxygen pitting

The symptoms of this are a loss of tube wall and aggressive localised boiler tube corrosion. The pitting happens when there is a large amount of oxygen in the water. It can happen during operation due to in-leakages of air pumps. Alternatively, there could be a failure in the working of pre-boiler water treatment gear. This can also happen if there are long out-of-service periods if proper procedures aren’t followed in layup.

Hydrogen damage

This issue can result in a loss of embrittlement or ductility in the tube material and intergranular micro-cracking. As for the causes, it is most commonly linked to considerable disposition on ID tube exteriors and a boiler water low pH excursion. Heavy scale on the tube exterior can also contribute to the failure, although it is not always the case.
