Japanese Patent JP7117086
Kind Code:
B2
Abstract:
To provide a resin pipe connection structure which maintains a strength and is improved in workability.SOLUTION: A resin pipe connection structure 10 comprises: a first resin pipe 11 and a second resin pipe 12 each of which is formed from a material containing a thermoplastic resin; and a joint 13. The joint 13 connects the first resin pipe 11 and the second resin pipe 12 in a state where ends 11a and 12a face each other. The first resin pipe 11 includes an abutment fusion end face 11c that is formed at a position in a predetermined distance from the end 11a in a direction of an axis O of the first resin pipe 11. When an outer diameter of the first resin pipe 11 is defined as D1 and the predetermined distance is defined as L1, (L1/D1)<4 is satisfied. The second resin pipe 12 includes an abutment fusion cross section 12c that is formed at a position in a predetermined distance from the end 12a in a direction of an axis O of the second resin pipe 12. When an outer diameter of the second resin pipe 12 is defined as D2 and the predetermined distance is defined as L1, (L1/D1)<4 is satisfied.SELECTED DRAWING: Figure 8
