JIG FOR EXPANDING DIAMETER IN CONNECTING-END PART OF FLUID PIPE MADE OF SYNTHETIC RESIN

摘要

PROBLEM TO BE SOLVED: To provide a jig for expanding diameter of a fluid pipe which simply enables expanding of the same on-site and is compact and easily carried. SOLUTION: The jig 100 for expanding diameter in the connecting-end part of a fluid pipe made of synthetic resin is constituted of bodies split into two and is equipped witch diameter-expanding parts 20 inserted into the connecting end part of the fluid pipe and with a separating means 30 for mutually separating the diameter-expanding parts 20. The diameter of the connecting-end part of the fluid pipe is expanded by mutually separating the diameter-expanding parts 20 inserted into the connecting-end part of the fluid pipe by means of the separating means 30. The diameter-expanding parts 20 are respectively formed in the body part 10 consisting of the bodies split into two. The separating means 30 mutually separates the diameter-expanding parts 20 by pressing the body part on the other side by the pressing member perforated through the body part on one side.
