Chemical Processing

Components within the chemical industry are generally exposed to many difficult, strongly interacting wear mechanisms: Corrosion, Erosion etc. Although corrosion attacks can be kept within limits by a suitable choice of base materials (ie special alloy), erosion caused by a solid particle suspended in a medium (gas or liquid) can be a serious problem.

Typical parts that suffer from wear in this, often highly aggressive environment are shafts and pumps. By identifying the media that is being pumped, Bodycote Metallurgical Coatings Limited are able to select a coating that will ensure high component protection. Coatings can be polished to provide a suitable surface for a seal. Reclaimation work is often carried out on high value components in addition to the application of coatings onto new components.

Chemical processing vessels are often subjected to chemical corrosion. The costs associated with manufacture of these large vessels from chemical resistant material can be significant. Thermally applied coatings are for more cost effective and with the vast range of materials now available it is viable to spray the vessel with a sealed coating that will give excellent resistance to the chemicals contained within.
