Title
(EN) PIPE FOR TRANSPORT OF CHLORINATED WATER
(FR) TUYAU DE TRANSPORT D'EAU CHLORÉE
Abstract
(EN)
The invention relates to use of a pipe for transporting chlorinated water, wherein the pipe is a biaxially oriented pipe made by a process comprising the steps of: a) forming a polymer composition comprising a polyolefin into a tube and b) stretching the tube of step a) in the axial direction and in the peripheral direction to obtain the biaxially oriented pipe.
(FR)
L'invention concerne l'utilisation d'un tuyau pour transporter de l'eau chlorée, le tuyau étant un tuyau à orientation biaxiale fabriqué par un procédé comprenant les étapes consistant à : a) former une composition polymère comprenant une polyoléfine sous forme de tube et b) étirer le tube de l'étape a) dans la direction axiale et dans la direction périphérique pour obtenir le tuyau à orientation biaxiale.
