Abstract

PURPOSE:To obtain a composite pipe, having excellent solvent resistance, used for transporting specific agents corroding a PE pipe and available at a low cost, by bringing the PE pipe into contact with a gas containing fluorine gas and fluorinating the surface of the above-mentioned PE pipe. CONSTITUTION:The aimed composite pipe obtained by bringing a PE pipe into contact with a gas containing at least fluorine gas (preferably blended gas of fluorine with nitrogen gas) and fluorinating the surface of the afore- mentioned PE pipe. Furthermore, fluorination is preferably accelerated by heating and pressurizing.
