Corrocoat Vietnam Extend Life of Pump

Posted On : Saturday, May 21st, 2016 in News

Licensed applicator, Vietnam GloCoating Engineering JSC (VGCE) was contacted by PetroVietnam Ca Mau Fertilizer JSC, as their engineers were concerned over the condition of one of their pumps. The pump is used in the production of nitrogenous fertilizers and was handling abrasive and corrosive chemicals.

VGCE engineers recommended a coating system that would protect the pump casing and impellor comprising:

All surfaces to be shot blasted to remove contaminants and achieve a surface profile of 75 µm. to allow the subsequent coatings to bond successfully and guarantee their longevity.

For the pump internals and impellor a coat of Corroglass 632, followed by Corrofil VE (to fill holes), Corroglass 602 and finally Corroglass 652 applied to achieve a total thickness of 1800 µm. This coating combination was recommended as it combined excellent abrasion and corrosion resistance and was therefore an effective and long term solution.

The pump casing external surfaces to be coated with Plasmet ZF at 250 µm, the pump housing flange faces rebated and the impellor balanced.

The contract was awarded to VGCE and the work carried out in its own workshops. The customer was delighted with the end result, marking the Work Completion Report – Good for both Service and HSE performance.
