HIGH-PRESSURE FLUID TRANSFERRING PIPING, HIGH-PRESSURE FLUID TRANSFERRING PIPING CONNECTOR, AND HIGH-PRESSURE FLUID TRANSFERRING PIPING DEVICE

摘要

PROBLEM TO BE SOLVED: To surely transfer a high-pressure fluid over a long period by forming a protecting sleeve for covering the circumference of a resin-made flexible pipe by cylindrically braiding a fiber excellent in sputtering resistance and mechanical strength. SOLUTION: In a high-pressure fluid transferring piping formed of a resin- made flexible pipe 1 and a protecting sleeve 2 put over the circumference thereof, the protecting sleeve 2 is formed by cylindrical braiding a fiber excellent in sputtering resistance and mechanical strength. The protecting sleeve 2 is formed by cylindrically braiding an aromatic polyamide fiber having a thickness of 100 deniers-2000 deniers. The resin-made flexible pipe 1 and the protection sleeve 2 put over the circumference thereof are collectively twisted into a part (ring member) 3 having a spiral groove 3a substantially fitted to the outer form of the resin-made flexible pipe 1, and the part 3 is housed in a facing part 4 having a connecting part 4a to the other piping.
