Abstract
Official abstract text for this publication.
A synthetic resin-made welding joint that has a pipe end portion into which an end portion of a synthetic resin-made tube is to be fitted and inserted, and that is configured so that the pipe end portion and the tube end portion which is fitted and inserted thereinto are enabled to be welded together by heating of heating means which externally surrounds the pipe end portion, therefore, a synthetic resin-made holder which is fitted and attached onto the pipe end portion is disposed, and a flange for ensuring a radial expansion gap with respect to the heating means is integrally formed in the holder.
First claim
Opening claim text (preview).
The invention claimed is: 1. A welding joint, said welding joint comprising a joint body, a synthetic resin-made tube and a synthetic resin-made holder, said joint body having a pipe end portion into which an end portion of said synthetic resin-made tube can be inserted and being configured so that said pipe end portion is welded to said end portion of said synthetic resin-made tube by heating of a heater which externally surrounds said pipe end portion, and said synthetic resin-made holder having a body portion and a flange which are fitted and externally attached onto said pipe end portion so as to be positioned between said pipe end portion of said joint body and said heater, said flange being connected to said body portion so as to make it possible to ensure a radial expansion gap between said body portion and said heater, and an outer diameter of said flange attached onto said pipe end portion being larger than an outer diameter of said body portion attached onto said pipe end portion, wherein an end surface, in a direction of an axis of said synthetic resin-made holder, of said body portion of said synthetic resin-made holder is coplanar with an end surface, in a direction of an axis of said joint body, of said pipe end portion. 2. The welding joint according to claim 1 , wherein a radial thickness of said flange is set to 1.4 to 15 times a radial thickness of said body portion. 3. The welding joint according to claim 1 , wherein a length of said holder in an axial direction of said holder is set to 2 to 10 times a length of said flange in the axial direction of said holder. 4. The welding joint according to claim 1 , wherein a resin having a melting temperature which is higher than a melting temperature of a synthetic resin forming said pipe end portion is set as the synthetic resin forming said holder.
