法及びこれに使用されるシール材に関するものである。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a sealing method for a resin-lined packing-type joint, particularly a mechanical pipe joint, and a pipe body connected thereto, and a sealing material used therein. It is related to.

、曲げ、引っ張り時の水密性は不充分なものでめった。<Problems with conventional technology and their solutions> Recent pipes often have a lining layer made of synthetic resin or the like formed on the surface of the steel pipe for corrosion prevention purposes, and mechanical joints are often used for the joints. However, the conventional methods of corrosion prevention, such as wrapping with tape or covering with heat-shrinkable tubes, are difficult to implement.
At present, it is inevitable that satisfactory results have not been obtained. On the other hand, there is a method of sealing resin-lined gasket-type pipe fittings with the pipe body by sealing them with gaskets inside the pipe joints, but this method has been unsuccessful because the watertightness during bending and tensioning is insufficient.

するものでおる。By screwing the tightening ring and the pipe fitting A in this state, the annular packing 12 connects the enlarged diameter portion 13 to the pipe fitting.
The fitting 10 is tightly press-fitted into the tube body C to provide a sealing effect to the fluid flowing through the tube body C, and at the same time, the opening fitting 10 is deformed into a substantially circular shape and the engagement protrusion bites into the lining layer of the tube body C, thereby tightening the tube body C. It must be fixed securely. Roughly, the sealing material B is pressed and deformed by the inclined surface 1 in the enlarged diameter portion 2 of the tightening ring, and as shown in FIG. It fills the gap between the tube body C and seals the gap to prevent corrosion of the fastener 10.

Examples include rubbers such as butyl rubber, ethylene rubber, propylene rubber, and polyvinyl chloride resin (plasticizer content 5
Examples include polyethylene resins, polypropylene resins, and polyester resins. The shape of the molded body 5 is not particularly limited as long as it has a substantially U-shaped cross section, but for example, as shown in FIG. 3A, a seal 8 is attached to the opening 7.
It is also a good idea to apply a ring to the ring, and when using it, either peel it off or insert it as it is and tighten it so that it is broken by the pressure of the ring. In FIG. 3B, cuts or grooves 9 are provided on the outer peripheral wall surface of the molded body 5 to prevent wrinkles from forming on the outer peripheral wall surface of the molded body 5 which is applied with a force of 11 by a ring.
