Abstract

The pipe structure according to the present invention includes: a fiber-reinforced plastic pipemoisture-proof foilswhich individually cover an outer circumferential surface of the pipeand an inner circumferential surface thereof; and an intermediate partwhich is made of metal and fitted to an end of the pipewherein end portions of the moisture-proof foilsare tightly sandwiched between the pipeand the intermediate partThis configuration reliably prevents an FRP pipe from absorbing moisture, and thus, prevents the FRP pipe from shrinking due to moisture exhaustion in outer space, whereby it is possible to obtain the pipe structure having excellent dimensional stability.
