| Abstract: | In the project of natural gas transportation from the western to eastern regions, it is an econom ic and practical method for natural gas transportion to mod ify existing civil gas pipelines with flexible composite joints. The paper describes a sort of high performance polyurethane-polyethylene glycol terephthalate (PET) fiber fabric-alu- m inium foil composite liner to be used as airtight joint structure of the gas pipeline. It introduces the gas pipeline mod ification technology developped by Chevalier-PRS (Asia) Hold ings Ltd. ofHongkong and test on the air-tight- ness, air pressure resistance, bend ing and peel strength, accelerated aging of the gas pipeline airtight joint struc- ture. The results show that the structure has excellent property and reliability and can be suitable for the natural gas transportation. |
