Water pipework
The history of water pipework
Post-WWII, an economic boom led to millions of new homes with water pipes expected to last 50-100 years. However, corrosion has plagued these pipes, causing leaks and releasing contaminants into drinking water.
In the 1970s, epoxy resins emerged as a game-changer for drinking water applications, providing a reliable alternative to ineffective materials like cement mortar and bitumen linings. Epoxy pipe linings applied in situ save time and cost compared to full pipe replacements.
Revolutionising Water Infrastructure
Epoxy resins, with their remarkable properties, have found their way into essential applications where strength, chemical resistance, moisture protection, and robust adhesion are vital.
Nipping Corrosion in the Bud
Due to water chemistry, pH, and temperature, corrosion can lead to metals like lead and copper leaching into drinking water. Epoxy linings create a barrier that prevents contamination and eliminates galvanic corrosion from the dissimilar metal joining.
Billions are spent annually to repair corroded water pipes, but epoxy repair systems offer a cost-effective solution. By relining existing pipes instead of replacement, cost savings of 50% to 60% can be achieved. The smooth surface of epoxy linings also lowers energy costs for water transport.
Epoxy linings ensure water quality by preventing the release of substances from corroded pipes, avoiding odour and taste issues. Their smoother surface reduces biofilm growth, promoting healthier water. Proper installation by trained experts guarantees epoxy’s safety and durability.
The process of epoxy coating preserves old pipe materials and surroundings like concrete or asphalt from ending up in landfills. Resource-saving and environmentally friendly epoxy linings contribute to a greener world.
Did you know?
Epoxy resins save the day, repairing damaged pipes at a fraction of the cost of installing new ones. By fixing existing pipes, epoxy avoids inconveniences caused to homeowners and public transport users during significant repair works.
