Joint structure of coupling equipped spiral wave equipped synthetic resin tube and spiral wave equipped synthetic resin tube

摘要

As with the simple structure whose number of articles is little, the sufficient we have water resistance pressure tightness and satisfactory seal Characteristic without at the same time needing the firm material and high precision, can assure cost conversion light weight conversion low, you handle, can do the joint job on site simply, joint structure of the coupling equipped spiral wave equipped synthetic resin tube and the spiral wave equipped synthetic resin tube is offered. From the destal of the above-mentioned spiral wave equipped synthetic resin tube directing to tube axis direction in the coupling equipped spiral wave equipped synthetic resin tube where corbel section 4 in order to joint the spiral wave equipped synthetic resin tube to the pipe arrangement destal has, the corbel section 4 which extends to tubed it forms by foaming Characteristic resin, that it features that the FRP formation 8a to which the joint side destal in the above-mentioned corbel section which formed in the peripheral face, impregnation could point to resin to the additional strength fiber at least is formed.
