I am asking for help if anyone can advise the service life of the HFT conduits in exposed environment. To my understanding HFT conduits use inhibitors for sunlight radiation protection and is suitable for 5-10 years service life. I am not sure whether the quoted service life is under direct sunlight or not. The project I am working on requires a design life of 15 years. The application for the use of the proposed HFT conduit run is not in direct sunlight, but under the eave of a building. Just wonder if the use of HFT conduit is able to meet the 15 years requirement.
Looking forward to receiving any feedback and will appreciate your help. Thanks in advance.
