Protect machinery in corrosive and erosive environments with Belzona coatings

Belzona’s comprehensive range of cold-curing, two-part polymeric coatings and repair composites has been utilized by the power industry for over 60 years. These materials are specifically engineered to withstand demanding operating conditions, offering exceptional wear resistance along with erosion and corrosion protection. Whether your plant generates power through nuclear, fossil, or renewable sources, or your facility distributes energy to end users, it is likely you will encounter routine or unexpected maintenance challenges that increase operating costs. Belzona provides cost-effective solutions to these maintenance issues by minimizing downtime, labor, and equipment replacement costs, while simultaneously enhancing plant efficiency and ensuring compliance with environmental regulations.

Repair and protection of fluid handling equipment

Aggressive erosion and corrosion in fluid handling equipment can reduce the hydraulic efficiency of cooling water systems. Belzona’s metal repair materials, such as Belzona 1111 (Super Metal), can restore damaged pumps and tube sheets, providing protection against chemical attack and deterioration. Coatings like Belzona 1321 (Ceramic S-Metal) and Belzona 1341 (Supermetalglide) offer long-term erosion and corrosion resistance, improving pump efficiency by up to 20%. Additionally, Belzona 2141 (ACR-Fluid Elastomer) helps protect turbine runners and other equipment from cavitation damage, reducing degradation and operating costs.

Abrasion resistant systems

Belzona polymeric coatings and metal repair composites can help to slow down the effects of erosion in solids handling and FGD systems, whilst resisting corrosion even in areas where chemicals and high temperatures are present. Our high build erosion resistant materials, such as Belzona 1311 (Ceramic R-Metal), Belzona 1811 (Ceramic Carbide) and Belzona 1812 (Ceramic Carbide FP), will restore eroded steelwork, whilst ceramic filled coatings such as Belzona 1321 (Ceramic S-Metal) can extend equipment life.

Pipework repair and protection

Thin-wall and through-wall defects from external corrosion can be effectively repaired using Belzona's wrap systems or cold plate bonding techniques. Belzona 1111 (Super Metal) is ideal for bonding repair patches, while Belzona 1212 offers a solution for bonding on oil or water-contaminated surfaces. Reinforced Belzona wraps are commonly used for low-pressure, non-critical equipment repairs, and Belzona SuperWrap II provides an ISO and ASME compliant solution for pressurized pipes, eliminating the need for traditional hot work. Additionally, Belzona 3411 (Encapsulating Membrane) prevents flange corrosion, and Belzona 3211 (Lagseal) addresses Corrosion Under Insulation (CUI).

Linings for chemical containment areas, channels and sumps

With the ability to be applied by brush or by airless spray, areas such as chemical bunds, channels and sumps can be effectively lined ensuring long-term environmental protection. Belzona’s comprehensive range of polymeric coatings such as Belzona 4311 (Magma CR1) provide chemical resistance against a wide range of aggressive chemicals.

Transformer oil and SF6 leaks

Environmental problems can occur because of deterioration of aging equipment resulting in leakage. Belzona 1161 (Super UW-Metal) has the unique attribute to bond strongly to oily and wet metal surfaces. Dependent on their location, even live leaks on pipework and other metallic equipment can be stemmed and sealed in situ using a Belzona leak sealing kit due to its high adhesion and cold curing capabilities.

These cold applied materials eliminate hot work and have been designed to be easy and safe to use. They are resistant to a wide range of chemicals and provide excellent corrosion protection offering long-term solutions.
