Overview

The steel industry operates in some of the most demanding conditions — extreme temperatures, heavy abrasion, corrosive media and constant mechanical stress. Belzona's polymer repair composites and protective coatings provide cost-effective solutions that allow repairs to be carried out in-situ, without the need for welding, hot work permits or lengthy production shutdowns.

From rebuilding worn pump impellers to protecting immersion tanks against aggressive chemicals, Belzona solutions extend the service life of critical steel plant equipment while minimising downtime and reducing maintenance costs.

Pump and equipment repair

Pumps used in the steel industry are subject to severe erosion and corrosion due to the abrasive slurries and aggressive media they handle. Belzona ceramic-filled repair composites such as Belzona 1311 (Ceramic R-Metal) and Belzona 1321 (Ceramic S-Metal) are ideal for rebuilding worn and damaged pump casings, impellers and housings, restoring original dimensions and providing outstanding resistance to further erosion and corrosion.

These materials can also be applied as a protective coating to new or refurbished equipment, significantly extending service intervals and reducing the frequency of costly shutdowns for pump overhauls.

Tank and vessel protection

Immersion tanks, acid baths, pickling vessels and chemical storage tanks in steel plants are subjected to highly corrosive environments. Belzona protective coatings provide long-term chemical resistance and prevent substrate corrosion, extending asset life and reducing the risk of costly leaks or containment failures.

Belzona cold plate bonding technology offers an alternative to welding for the repair of damaged tank walls and structural components, allowing repairs to be carried out safely without the need for hot work — particularly important in hazardous or confined environments.

Pipe repair and corrosion protection

Cooling circuits, hydraulic lines and process pipework in steel plants are vulnerable to corrosion, erosion and mechanical damage. Belzona metal repair composites allow quick, effective repairs to be carried out on corroded or damaged pipe walls, restoring structural integrity without the delays associated with traditional welding or pipe replacement.

Belzona SuperWrap II can also be used to reinforce and protect pipes and vessels, providing a high-strength composite wrap that complies with ISO 24817 and ASME PCC-2 standards.
