Title:
FIBER-REINFORCED RESIN PIPE WITH METAL PIPE
Document Type and Number:
Japanese Patent JPH03213789
Kind Code:
A
Abstract:

PURPOSE: To prevent the disturbance of winding of fiber in a resin layer by arranging each metal pipe at both the edges of a straight trunk part as dummy layer, laminating a fiber-reinforced resin layer over the outer peripheral surfaces of the straight trunk part and the metal pipe and forming the outer peripheral surface of the inner edge part of the metal pipe, in parallel to the inner peripheral surface of the inner edge part.

CONSTITUTION: Each metal pipe 1 having a tapered surface is arranged at both the edges of a straight trunk part 2. The metal pipe 1 is utilized as a coupling in the connection use of several fiber-reinforced resin pipes. The outer surface of the metal pipe 1 is applied with an adhesive 4 beforehand. The taper is formed so that the outside diameter of the metal pipe 1 gradually increases towards the outer edge from the inside edge. The outer peripheral surface 11 of the inner edge part 1a of the metal pipe 1 is formed parallel to the inner peripheral surface 12 of the inner edge part 1a. Accordingly, the fiber winding state in the vicinity of the boundary part is made tight, and leak is prevented, and dimension stability, pressureproofness, etc. can be improved.
