HOT!... in this case we are talking about hot-dip galvanisation
For many years now, all BBA Pumps frames and canopies are supplied with a hot-dip galvanised coating. Every BBA Pump user, wherever they may be located in the world, understands and appreciates the value of this durable, environmentally friendly and unique method of steel protection.
The hot-dip galvanising process
The galvanising process follows several steps: after degreasing, pickling, fluxing and drying, the steel components are submerged in a bath of molten zinc with a temperature of 450 ºC. Using this method, a layer of zinc bonds with the steel, creating an unbreakable zinc alloy coating resulting in the galvanised materials being extremely durable, maintenance free and providing a unique level of protection.
The zinc alloy is hard, both abrasion and shock-resistant and also performs well against mechanical stress. Even in the event of damage to the coating a resulting chemical reaction – cathodic protection – will protect the material, which is why a properly galvanised product will not corrode. Only galvanising provides this unique protection. This also means that cutting edges or drill holes added after the galvanising process will have no effect on the service life.
Galvanising is carried out in accordance with NEN-EN-ISO-1461. The general characteristics and test methods for hot-dip galvanised coatings applied to steel objects are defined in this standard.
When a hot-dip galvanised product ultimately is replaced, the materials are not lost. Steel and zinc materials are recoverable and can be recycled. The service life of certain products can also be extended considerably by removing the galvanised coating and re-galvanising them.
The small amount of zinc that is lost enters the cycles of life as an essential element, playing a useful role there also.
In the hot- dip galvanising process the liquid zinc flows into even the most difficult to reach areas such as seams and gaps, thus, coating also the inside of the housing. Conventional protection systems struggle to adequately provide protection around edges and corners as the protective layer in these areas is often too thinly applied. With hot-dip galvanising, the zinc coating in these areas is strong, thick and of high quality.
