Problem: Erosion-corrosion is a problem which affects most valves due to the environments in which they operate coupled with the operating regime which can induce impingement and cavitation damage.
Belzona Solution: The Belzona 1000 Series Metallic Polymers range includes erosion-corrosion resistant materials which can be used to rebuild and re-profile the valve bodies and coat and protect from further erosion-corrosion damage.
Working procedures for this application as well as product options can be obtained from your local Belzona Technical Consultant.
Rebuild slides and guides
Problem: In many cases the slides and guides of gate valves suffer not only from erosion-corrosion but from a specific form of corrosion - crevice corrosion. This normally occurs between the valve slide and the guide particularly when the valve is closed for long periods.
Belzona Solution: The Belzona 1000 Series Metallic Polymers range includes erosion-corrosion resistant products which can be used to rebuild and re-profile guides and slides and prevent further corrosion from taking place. Working procedures for this application as well as product options can be obtained from your local Belzona Technical Consultant.
Repair existing linings
Problem: Most valve bodies are manufactured from cast metals and consequently if they become cracked due to expansion/contraction or impact, they are very difficult to weld.
Belzona Solution: Belzona 1000 Series Metallic Polymers can be used to seal cracks without inducing any physical stress into the castings.
Other Belzona Know-How applications for valves include:
Rebuild thread bushes.
Rebuild/resurface gland housings.
Realign/reseat butterfly valve shaft location and bush housings.
Rebuild and protect interior surfaces.
Repair/resurface rubber diaphragms.
Strengthen corroded flanges.
PIPES
Repair and protect weld seams
Rebuild and protect pipes against erosion.
Problem: Pipework suffers from many different problems including erosion-corrosion, impact damage, weld corrosion and abrasion. Conventionally, problems such as these may well lead to the entire system having to be closed down and drained before any repair process or replacement can begin.
Belzona Solution: Belzona 1000 Series Metals and Belzona2000 Series Elastomers allow most pipework problems to be repaired while the pipework is still on-line.
Repair and seal pipe expansion bellows
Problem: Flexible expansion pieces are an extremely important part of all pipework systems. The fact that all movement within the system is focused around these pieces of equipment means that splits in the fabric of the expansion bellows due to fatigue, are not uncommon.
Belzona Solution: Belzona 1000 Series Metals and Belzona2000 Series Elastomers enable the maintenance engineer to quickly repair this type of equipment saving money in both downtime and replacement costs.
Other Belzona Know-How applications for pipes include:
Repair existing linings.
Repair leaking pipes.
Repair steam cut or wire drawn flanges.
Re-form/reseat distorted or corroded flange faces.
Isolate flange space s and orifice plates.
Protect internal and external surfaces against corrosion and chemical attack.
Repair and protect concrete pipe joints.
FITTINGS
Rebuild and repair erosion-corrosion damage
Problem: Many pipework fittings such as filters, flanges and surge tanks suffer from internal erosion-corrosion damage.
Belzona Solution: Belzona 1000 Series Metallic Polymers include erosion-corrosion resistant products which can be used to protect these pieces of equipment and thus extend the life of the equipment.
Other Belzona Know-How applications for fittings include:
Protect internal surfaces against corrosion.
Create insulation, self-lubricating, or vibration-dampening linings for pipe supports and hangers.
Protect and encapsulate insulation.
