次の二つの方法が知られている。The other method is to butt the flange-shaped product, which has an approximately L-shaped cross section by forming a short pipe member having the same inner and outer diameters as the thermoplastic resin pipe and a flange member, against the end face of the thermoplastic resin pipe. This is a method of fusing. Furthermore, the following two methods are known as conventional methods for manufacturing flanged resin composite pipes.

である。The other method is disclosed in Japanese Patent Application Laid-Open No. 14920/1983. This method involves inserting a master shape wound with glass fiber into the cavity of a mold that is divided into an upper mold and a lower mold, and then injecting thermosetting resin through the gate to connect the cavity surface and the master mold. A thermosetting resin is press-fitted into the gap to impregnate and harden the thermosetting resin into the original glass fiber.

しかし、従来のフランジ付熱可塑性樹脂管の製造方法に
は、次の問題点があった。(Problems to be Solved by the Invention) However, the conventional method for manufacturing a flanged thermoplastic resin pipe has the following problems.

ック等が入りやすいものとなる。また、品質のバラツキ
が多く、製造の手間がかかる。In the method of welding a plate-shaped flange member made of thermoplastic resin to a thermoplastic resin pipe, since the welding is used for joining, the resulting pipe has low bending strength and shear strength, and is prone to cracks. . In addition, there are many variations in quality, and manufacturing is labor-intensive.

るため、口径の大きなものに対応できなかった。In addition, in the method of fusing a flange shaped product to a thermoplastic resin pipe, there are problems in that when a flange or shaped product that has been machined is used, it takes more man-hours to manufacture and increases the manufacturing cost. there were. In addition, when a flange or shaped product made of an injection molding type is used, a mold for the injection molding is required, so that it cannot be used for large diameter products.

性が良くなかった。On the other hand, in the conventional method for manufacturing flanged resin composite pipes, the outer surface of the flanged thermoplastic resin pipe and the outer surface of the flange are coated with fiber-reinforced thermosetting resin. There were similar problems with the method. Furthermore, the adhesiveness of the fiber-reinforced thermosetting resin was not good at the corner between the outer surface of the tube and the outer surface of the flange because it was difficult to perform surface treatment.

ンジ付熱硬化性樹脂管を得ることができる。(Effects of the Invention) As explained above, according to the method for manufacturing a flanged thermoplastic resin pipe according to claim 1, the molten resin bulges at the corner between the outer surface of the tube and the outer surface of the flange, so that
A flanged thermosetting resin pipe with high bending strength and high shear strength at the flange joint can be obtained.

ンジ付熱硬化性樹脂管を製造できる。しかも、金型等を
必要としないため、口径の大きなものに対応できる。Moreover, since it is only necessary to prepare a thermoplastic resin pipe and a flange member provided with an extra wall portion, a flanged thermosetting resin pipe can be manufactured easily and at low cost. Moreover, since no mold or the like is required, it can be used with large-diameter products.

フランジ付樹脂複合管が得られる。The method for manufacturing a flanged resin composite pipe according to claim 2 also provides the same effects as the method for manufacturing a flanged thermoplastic resin pipe according to claim 1. In addition, since the molten resin fills the corner between the outer surface of the tube and the outer surface of the flange, the surface treatment is uniform on the outer surface of the tube and the outer surface of the flange, and the fiber-reinforced thermosetting resin is uniformly coated. . Therefore, a flanged resin composite pipe with high strength can be obtained.
