Corrosion & Abrasion Solutions Ltd. (CASL) is a trusted advisor to heavy equipment mining operators with almost a half century of experience providing quality, fit for purpose solutions to the industry’s most challenging hydraulic cylinder, strut, center joint, snubber and track adjuster component repair challenges.
CASL recognizes the importance of flexibility in terms of repair scope and tailors solutions to client requirements, ensuring equipment owning and operating costs meet expectations. CASL offers comprehensive remanufacturing where extended service life is expected, down to more modest repairs when a value solution is the preferred option.
CASL intimately understands the importance of accurate, timely cost estimates and rapid turnaround when the repair approval is granted.
CASL has a full-service hydraulic facility dedicated to the repair, testing, and remanufacturing of hydraulic equipment.

GET – Ground Engaging Tools
CASL provides severe service wear protection for GET (Ground Engaging Tools) with PTAW tungsten carbide overlays for maximum service life.
In applications where hang-up or carry-back create serious challenges, or where clients desire prolonged service life, CASL provides a fusion bonded, single pass chrome carbide overlaid plate. This unique process, depositing alloy between 6mm and 12mm in a single pass, minimizes dilution and yields a product with a lower coefficient of friction than even standard quenched and tempered plate. CASL can work from a print or scan and measure your application to deliver cut and formed kits ready for immediate installation.
BENEFITS OF CASL OVERLAID WEAR PLATE INCLUDE:
Excellent anti hang-up and carry back qualities – more material and less weight per trip
Very low residual stress means less susceptible to cracking and spalling with better impact resistance
Uniform microstructure down to the fusion line results in consistent and predictable wear rates
No plate distortion during manufacturing eliminates the need to press plate flat and therefore reduces cracking
Very long service life, typically 5X longer than Q&T plate and 2X longer than standard chrome carbide overlay
CASL provides a comprehensive remanufacturing program for severe service slurry valves. Using either standard chrome carbide overlay for moderate duty service, or CASL’s unique spray and fuse applied tungsten carbide overlay (“WCO”) for severe service, mine operators can expect a fully remanufactured valve with a coated gate and liner system designed to meet your specific application.
OUR WCO LINER AND GATE SYSTEMS:
Yield significantly longer service life than standard chrome carbide liners
Can be repaired, reducing ongoing owning and operating cost
Are available in a number of thicknesses: 6mm – 14mm WCO liner systems available
CASL’S COMPLETE VALVE REMANUFACTURING SERVICE INCLUDES:
Complete valve disassembly, inspection and rebuild
Valve body weld build-up and machining
Gate weld repair and hardfacing
Inspection and testing of all welds
Hydraulic cylinders remanufactured to new condition
MPI inspection of critical welds
Tungsten or chrome carbide overlaid wear liners
Overlaid Piping Spools
Clients seeking prolonged service life for slurry pipe exposed to a severe environment, such as oilsands tailings, will benefit from CASL’s turnkey spool fabrication and overlay service. CASL’s unique spray and fuse tungsten carbide overlay process allows application of eutectic tungsten carbides, which provide better impact resistance and wear properties than virtually all other spool coating or liner systems. Enjoy the benefit of CASL’s extensively field tested ST66 alloy or engage our materials science team to develop a custom blend to meet a specific performance objective.
TURNKEY PIPING COMPONENTS
Straight pipe & elbows
Wyes & tees
Reducers & transition rings
TUNGSTEN CARBIDE OVERLAYS
High hardness Eutectic WC/W2C (up to 2500Hv)
4mm to 25 mm thicknesses
Tungsten carbide repairs
