EVOH Barrier Pipes

Haili Pipe manufactures high-performance EVOH Barrier Pipes designed for advanced heating and plumbing systems where oxygen protection is critical. Featuring an Ethylene Vinyl Alcohol (EVOH) oxygen barrier layer, these pipes are widely used in underfloor radiant heating, hydronic heating systems, HVAC installations, and other closed-loop water circulation systems in residential, commercial, and industrial buildings.

In radiant floor heating applications, Haili EVOH Barrier Pipes effectively prevent oxygen from penetrating the pipe wall and entering the circulating water. This significantly reduces the risk of corrosion in metal components such as boilers, pumps, manifolds, valves, and heat exchangers, extending the service life of the entire heating system while lowering maintenance costs.

Commercial buildings, hospitals, hotels, office complexes, and educational facilities rely on EVOH Barrier Pipes to maintain stable system performance and improve long-term operational efficiency. The pipes are also suitable for geothermal heating systems, heat pump installations, and low-temperature hydronic networks where reliable oxygen resistance is essential for protecting equipment.

Manufactured from premium PE-RT or PEX materials with an integrated EVOH barrier layer, Haili Pipe products combine excellent flexibility, high temperature resistance, pressure durability, and easy installation. Their smooth inner surface minimizes flow resistance and prevents scaling, while their lightweight design simplifies construction. With a service life exceeding 50 years under normal operating conditions, Haili EVOH Barrier Pipes provide energy-efficient, corrosion-resistant, and dependable piping solutions for modern heating projects worldwide.
