Composite Materials

Service

Repair and protection of a variety of machinery parts by composite materials, where hot works/welding methods are not permissable and downtime is minimum.

Typical examples:

Pump Casings

Rebuilding of cutwaters, flow straighteners, casing ring housings, bearing housings etc. Protection against cavitation, corrosion, erosion etc. Efficiency enhancing (up to 7%) applying hydrophobic coatings. Repair of holed or cracked casings.

Pump Impellers

Protection against cavitation,erosion chemical attack and corrosion increasing working life of the impeller and minimising life cycle cost. Rebuilding of eroded or damaged vanes. Efficiency enhancement applying hydrophobic coatings.

Engines

Repair of damaged casings. Reseating of cylinder liners. Rebuilding of liner seats and seals. Protection against corrosion on liners and cylinder block.

Heat Exchangers

Rebuilding of corroded/eroded tube sheets, damaged water boxes, end covers and channels. Protective coatings against corrosion and erosion for brand new or old parts.

Fans – Blowers

Rebuilding and protecting fan blades. Applying protective coatings against abrasion/corrosion/erosion. Rebuilding of internal casings.

Power Transmission

Repairs of shafts at bearing location. Keyway repair. Rebuilding of bearing housings and tapered couplings.

Tailshafts / Rudders

Rebuilding of oversized pintles/pintle housings. Coatings against erosion, cavitation and corrosion . Bonding pintle sleeves. Protection of propeller shafts. Repairing seal areas on pitch propellers.

Air Motors

Rebuilding of vane guides.
