SprayClad ® ‘Best in Class’ for Boiler Protection

The SprayClad ® solution is an arc spray process developed to deliver a bond and hard coat, finished with a sealant that reduces slagging and the need for frequent cleaning. The bond layer, applied to the base material provides a level of corrosion resistance, engineered for thermal expansion and provide’s a secure strong adhesion between the base material and subsequent layers like hard coat. The hard coat or hardfacing layer can be applied utilising various material from the Welding Alloys consumables portfolio to protect against erosion, corrosion or both, depending on the wear mechanism. The final layer, a sealant, is applied consisting of advanced ceramics offering corrosion and erosion protection with the added benefit of exhibiting smooth anti-fouling properties.

Designed to withstand long exposure to corrosive gases and salts at high temperatures that corrode and erode the boiler and heater tubes. SprayClad ® can be customised to help solve the challenges faced by many of our customers, and contribute significantly to reduce thinning of tube walls, boiler downtime and the cost of in situ tube cladding.

SprayClad ® has been developed in collaboration with world leading academic organisations and tested with leading OEM’s and international welding and materials experts. It has proven to increase the lifetime and performance in many applications and is deposited up to 6 times faster than traditional cladding techniques, meaning repairs can be carried out quicker. Using WA Mill kits to perform repairs and maintenance allows for rapid deposition rates. Being a “cold process” distortion and adverse metallurgical effects on the base material are non-existent, and the process is carried out without the need of water inside the heat exchanger tubes.

Our team of expert engineers are located at 25 Integra centres around the globe and have over 30 years’ experience providing advanced wear solutions in the repair and maintenance sectors across a number of industries. Offering wear audits of parts, installations and equipment located within the plant to assess wear mechanisms and phenomenon, allow us to recommend and provide the best possible wear solutions to our customers making WA the ‘total solution provider’.
