摘要： PROBLEM TO BE SOLVED: To provide an exchange joint for quickly joining an existing pipe such as a gas conduit to a renewal pipe formed of a thermoplastic resin such as polyethylene and pulled therein.
SOLUTION: The exchange joint 1 comprises a joint body 2 covered with a cover resin 3 and having a first socket 4a for receiving a steel pipe (the existing pipe 21) via a packing 12a and a second socket 4b for receiving the resin pipe 22 via a packing 12b, a first pressing ring 6a for compressing the packing 12a, and a second pressing ring for compressing the packing 12b. The packing 12b is held between a protecting ring 11 to be mounted between the resin pipe 22 and the second pressing ring 6b and a retainer 13b. The retainer 13b abuts on a lock ring 15 to be bitten into the resin pipe 22 and on an adapter 17 for moving toward the packing 12b a lock ring 15 being pressed by the engagement with the second pressing ring 6b. At the end of the adapter 17, a water tight packing 10c is provided to be put in close contact with the resin pipe 22.

摘要： PROBLEM TO BE SOLVED: To provide a method of joining together the ends of synthetic pipes having an ultra-small wall thickness or any pipe end with a pipe fitting.
SOLUTION: A spring core 18 in a coil shape is inserted into the joining ends 14a of an inner surface fitting 14 made of synthetic resin. Each joining end 14a with the spring core 18 fitted is inserted to the joining end 10a of an insertion pipe 10 made of synthetic resin, and these ends 10a and 14a are joined together by means of hot fusion attachment. At this time of hot fusion joining, the inner surface fitting 14 is held by the spring core 18 from inside, and therefore, the inside surfaces 10b of the joining ends 10a and 14a can be contacted with the outside surface 14b by a contacting pressure required to make a fusion joining. Thereby the joining end 10a of the insertion pipe 10 having an ultra-small wall thickness can be put in hot fusion joining certainly. Because an ultra-thin pipe can be adopted as the insertion pipe used upon hot fusion joining, the rate of flow can be increased in an amount according to the small wall thickness. Because spring core is used in the join, the joint part can pass smoothly any bent part of an existing pipe owing to the flexibility of the spring core.

SOLUTION: After a preparation process S1, a base treatment for forming a base surface having a specific color on an inside tube surface is applied to a tube (base treatment process S2), and a lining film becoming translucent at a thickness less than the set film thickness is formed on the base surface (lining film formation process S3). The color of the lining film is observed from the upper side of the formed lining film (observation process S4), and the construction state of the lining film is confirmed based on the observation color obtained by the observation (confirmation process S5).

摘要： PROBLEM TO BE SOLVED: To provide a circle cutting machine for the perimeter of a pipe penetrating portion which circularly cuts an area on the perimeter of the pipe penetrating portion in a manner being almost concentric with the pipe and with a minimum diameter in order to repair the pipe of a different type arranged in a structure.
SOLUTION: The circle cutting machine is formed of a holding section 1 which holds the pipe A and is rotatably held, a dish-like rotary blade 3 pivotally mounted on a driving unit 2 in one body via a transmitting means, and a machine body 4 connecting the driving unit 2 to the holding section 1. The driving unit 2 is slidably connected to the machine body 4 in a restricted range restricted by a sliding restricting means 5 for restricting the sliding of the driving unit 2 to a predetermined direction and to a predetermined length. The rotary blade 3 has its dish-like recessed face adjacently formed to the holding section 1. Thus by the sliding of the rotary blade 3 caused by the sliding of the driving unit 2 and by the rotation of the rotary blade 3 on the pipe A caused by the pressing motion of the machine body 4, the area B on the perimeter of the pipe penetrating portion is circularly cut almost concentrically with the pipe A and with the minimum diameter.
