Claims8
A fiber-reinforced resin pipe comprising:
- a plurality of introduction/discharge parts for introducing or discharging a liquid via a peripheral surface of the pipe, the introduction/discharge parts being arranged at intervals in an axial direction, wherein each introduction/discharge parts comprises a through-hole formed in the peripheral surface of said pipe and a cylinder having a collar at one end thereof, the cylinder being provided in the through-hole;
- a spacer provided between the collar of the cylinder and an internal peripheral surface of said pipe, the spacer having a curved upper surface shape that conforms to a curved shape of the internal peripheral surface;
- and
- a first seal member for forming a seal between an external peripheral surface of the cylinder and an internal peripheral surface of said through-hole provided to the external peripheral surface of said cylinder.
1 more element
An introduction/discharge part comprising:
- a cylinder;
- a collar disposed at one end of the cylinder;
- and
- a spacer through which the cylinder protrudes, the spacer having a bottom surface that faces an upper surface of the collar, wherein the spacer comprises an upper surface opposite the bottom surface of the spacer, the upper surface of the spacer having a curved shape configured to conform to a curved shape of an inner peripheral surface of a pipe about a through hole of the pipe in which the cylinder is to be inserted;
- and
- a first seal member disposed about an external peripheral surface of the cylinder for forming a seal between an external peripheral surface of the cylinder and an internal peripheral surface of the through-hole provided to the external peripheral surface of the cylinder.
