Repair the suction cover back to the original dimensions. Then to also give better protection to the substrate from the abrasive pumped media.
Corroserve proposed to rebate and pre-machine to accommodate the coating process. Masked the areas not requiring treatment. Grit blasted to ISO850-1, internals and all wetted areas to Sa2 1/2 and externals to Sa2. Then applied multiple coats of Plasmet HTE to achieve a minimum DFT 2.0mm to the pump internals, thickness checked and spark tested. Post machined as required. Then finally applied two coats of Plasmet ZF to the suction cover external areas.
The suction cover was returned back to its original dimensions, with the added benefit of being more abrasion resistant due to the Plasmet HTE coating. Plasmet HTE is a viscous, solvent free, amine cured epoxy containing stainless steel flakes, glass flakes and silicon carbide. It has excellent abrasion and chemical resistance in immersed environments and is also useful for building up damaged areas where impact or abrasion are prevalent.
We have the experience and expertise to either coat from new or provide remedial coatings to process equipment. The bespoke coating systems used are determined by the operating conditions and mediums. Our coating systems have provided unrivalled levels of corrosion in the harshest environments in over 40 years.
