Title
(EN) MULTI-LAYER PIPING FOR CONVEYING AND HEATING A FLUID
(FR) SYSTEME DE TUYAU MULTICOUCHE POUR L'ACHEMINEMENT ET LE CHAUFFAGE DE FLUIDE
Abstract
(EN)
A multi-layer piping (1) for conveying and heating a fluid, in particular an aqueous urea solution including a fluid conveying pipe (2) comprising a thermoplastic elastomer, a heating element (3), a sealing element (4), an insulating layer (5) and an anti-abrasive layer (6). Preferably, it is used a polyolefin matrix based thermoplastic elastomer in which is intimately dispersed a dynamically vulcanised and EPDM based elastomeric phase.
(FR)
Système de tuyau multicouche (1) pour l'acheminement et le chauffage de fluide, en particulier une solution d'urée aqueuse, qui comporte une conduite d'acheminement de fluide (2) à élastomère thermoplastique, un élément chauffant (3), un joint (4), une couche isolante (5) et une couche anti-abrasion (6). On utilise de préférence un élastomère thermoplastique en matrice polyoléfinique contenant une dispersion intime de phase élastomère à base d'EPDM qui fait l'objet d'une vulcanisation dynamique .
