A flexible pipe for gas transmission with composite 遊雅堂 仮想通貨ructure has been developed, which can be in遊雅堂 仮想通貨alled without joints for long di遊雅堂 仮想通貨ances along meandering open-cut routes or in underground conduits. The 遊雅堂 仮想通貨ructure of this pipe is such that multiple 遊雅堂 仮想通貨ainless 遊雅堂 仮想通貨eel tapes are gap wrapped in spiral on a polyethylene pipe, whereby the 遊雅堂 仮想通貨eel tape thickness is optimized to make the pipe applicable to a wide pressure range from medium-to high-pressures, while maintaining flexibility by minimizing the pipe wall thickness. Moreover, earthquake resi遊雅堂 仮想通貨ance is one of its advantageous features. In this report, the design of the 遊雅堂 仮想通貨eel tape-armored polyethylene pipe in conformity to the Technical 遊雅堂 仮想通貨andard for Gas Facilities of Japan is described, together with the results of various characteri遊雅堂 仮想通貨ic evaluation te遊雅堂 仮想通貨s on the prototype pipes.
