Pipes for heating - Import export

Floor heating systems made of heating pipes of polybutene (PB), polypropylene (PP) or cross-linked polyethylene (PEX) can cause potential corrosion of the metal parts in the heating element due to the oxygen that easily permeates through the plastic pipes and into the heating circuit. To avoid this corrosion several options can be taken: using corrosion resistant material adding rust-preventive agents into the water reducing the oxygen permeability of the pipe. Reducing the oxygen permeability of the pipes is the most secure and economical solution. By using a multilayer pipe made of plastic containing an EVALâ„¢ barrier layer, the oxygen transmission rate will be reduced to a minimum and the corrosion of the metal parts in the heating system is minimised. The gas barrier property of the EVALâ„¢ resins prevents oxygen from permeating through the wall of the pipe and subsequently dissolving into the circulating hot water, thereby corroding metal parts in the heating element.

The excellent barrier properties and the chemical resistance of EVALâ„¢ resins make them suitable for several industrial applications. The chemical resistance of EVALâ„¢ ensures the effectiveness of the barrier needed for chemical packaging material for instance. The outstanding oxygen barrier of EVALâ„¢ helps to minimise the oxygen permeation of heating pipes with excellent ageing resistance and long-term thermal stability. EVALâ„¢ offers the following benefits: outstanding gas barrier properties excellent resistance to chemicals long-term thermal stability flexibility
