Maintenance of pipework is critical in every industry and facility. Common causes of damage and deterioration to pipes, valves, and fittings include impact and frost damage, corrosion, erosion, and chemical attack.
At WPS, we offer a wide range of cold-curing repair materials and high-performance coatings specifically designed to provide outstanding erosion and corrosion protection while demonstrating excellent chemical resistance. These materials can be used to rebuild valve bodies, guides, slides, diaphragms, and expansion bellows and protect them from further damage.
Our cold-curing composite repair materials restore strength to weakened or damaged pipes. Solutions include bonding patches over damaged areas and applying reinforced wraps for permanent repairs of low-pressure, non-critical equipment. For high-performance needs, we offer systems designed and applied in accordance with international standards such as ISO 24817 and ASME PCC-2, providing a downtime-saving alternative to welding. These solutions are suitable for a range of climates and service temperatures up to 150°C (302°F).
Our materials are also used to restore damaged flange faces exposed to harsh chemicals, crevice corrosion, galvanic corrosion, and high-pressure steam. For long-term external protection, flanges, fastenings, and associated pipework can be encapsulated using a peelable, resealable coating designed to exclude moisture and prevent atmospheric, galvanic, and crevice corrosion.
