Title:
POLYMER DUCT AND CONNECTION MEMBERS FOR ASSEMBLING THE SAME
Document Type and Number:
WIPO Patent Application WO/2000/028247
Kind Code:
A1
Abstract:
The present invention relates to a polymer duct that comprises a plurality of polymer tubes including reinforcements in the form of a three-dimensional reinforcing frame which is arranged in the monolithic polymer. The polymer duct also includes a plurality of connection members, wherein the body of each connection member is made of a monolithic polymer having a reinforcing frame arranged therein. This frame is perforated and comprises a ring as well as a plurality of longitudinal members which co-operate with said ring and are arranged thereon so as to be capable of radial displacement. The width of the ring is commensurate with that of the cold area. Heating members in the shape of electro-conductive spirals are further provided on the side of the connection-member inner surfaces. The connection members may be made of a monolithic block of polymer in the form of a sleeve, a T joint, a branching or a crosspiece.
