DUOPEX GAS PIPES must be protected against direct sunlight or UV radiation. Consequently, DUOPEX GAS PIPES must be covered during transport or storage if they have been removed from their original packaging. When DUOPEX GAS PIPES are used in a protective tube adequate UV protection is assured during the installation phase. Furthermore, jackets made from insulating material can undertake the function of UV protection with DUOPEX GAS PIPES. See catalogue p.34
