Field Service

CASL provides quality on-site application of high velocity thermal sprayed coatings for a variety of severe service applications. CASL deploys high-energy powder combustion and twin wire electric arc systems to provide clients with dense, high strength, low porosity coatings to protects and extend asset life.

CASL’s in-house, experienced technical team works closely with clients to comprehensively understand the wear problem and develop a customized fit-for-purpose solution. CASL’s variety of thermal spray systems provides the ability to apply a vast range of coating materials – from aluminum to zinc and all of the alloys in-between. We are Western Canada’s preferred Hastelloy® thermal spray service provider; this coating is the industry go-to for protection against corrosion problems in the oil and gas industry.

Thermal spray is used predominately to protect tanks and vessels from corrosion but may also be suitable for combined corrosion/erosion applications. Typical on-site thermal spray alloys are:

Aluminum for atmospheric corrosion, corrosion under insulation (CUI), corrosion under fireproofing (CUF), saltwater corrosion and sulphur attack
Stainless steels for moderate corrosion
Zinc for atmospheric corrosion
Hastelloy^® materials for chloride environments and exceptional corrosion, pitting and erosion resistance
Amorphous nickel based materials for high temperature wear resistance and moderate impact abrasion applications
Custom alloys, which can be manufactured for special needs upon request

Some of the typical on-site thermal spray applications include:

Amine Towers and Reboilers
Flash Drums
Weak Acid Cation (WAC) Vessels
Heat Exchangers
Fractionators
Tanks
Separator Vessels
Sulphur Condensers
Waste Heat Boilers

Some advantages of thermal sprayed coatings:

Higher service temperatures than most other coating processes
There are no metallurgical changes made to the substrate during the application process
Thermal sprayed coatings can provide both barrier and galvanic protection
Wide selection of alloys can be matched to even the most severe service environments
Coatings can be applied during typical maintenance shutdown windows
There is no cure time; thermal sprayed coatings can be put into service immediately after application
Thermal sprayed coatings can be tied into and extended at later maintenance shutdowns
