Title
(EN) PIPES FOR CARRYING WATER
(FR) TUYAUX POUR TRANSPORTER DE L'EAU
Abstract
(EN)
A water delivery pipe made from PVC or PVCO and having an inner surface which is rifled. The inner surface of the pipe preferably comprises a graphene material. The pipe has improved anti-bacterial properties such that the formation of bacterial biofilms is eliminated or reduced. Methods of making the pipe are also disclosed.
