摘要： PROBLEM TO BE SOLVED: To consistently form a locking projecting bar of the high quality on various pipe bodies irrespective of the diameter size of the pipe bodies and irrespective of the wall thickness of the pipe bodies when forming the locking projecting bar on an outer circumferential surface of a pipe end joint of a fluid feed pipe by the form rolling method. SOLUTION: When forming a locking projecting bar on an outer circumferential surface of an end of a pipe body by the form rolling method by using an inner form rolling roll 5 located inside a pipe body to be worked, and an outer form rolling roll 6 having a forming annular groove located outside the pipe body, the locking projecting bar is formed while imparting the pressure in the axial direction of the pipe body to the pipe body. The flow of a pipe body material required for forming the locking projecting bar is sufficiently performed to consistently form the locking projecting bar having the uniform height and wall thickness.

摘要： PROBLEM TO BE SOLVED: To provide a piping method reduced in the number of portions where pipe joints are used by using a branch pipe. SOLUTION: A branch pipe 1 formed of a main pipe part 1a formed of a straight pipe and a branch pipe part 1b projected midway from the main pipe part 1a is manufactured beforehand. After the branch pipe part 1a of the branch pipe 1 is cut to a required length at an installation site for city water pipes, the branch pipe is connected to the city water pipe of a building through a pipe joint 4. Since the number of connections can be reduced due to the presence of the pipe joint 4, the efficiency of the piping can be increased. In piping where a large number of pipe joints 4 are used, the cost of parts can be remarkably reduced, man-hours required for inspections can be reduced since the inspection points after piping using less number of pipe joints 4 can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide an indicating device that prevents troubles such as leaking of liquid after piping work caused by forgetting to tighten bolts and nuts or not tightening them insufficiently. SOLUTION: A flat washer 6a that has a flat part 6b on the outer circumference and a tapered part 6c on the inner circumference is laid facing a protruding surface of a tapered part 6c each other either between a head part 2b of a bolt 2 and a protruding part 1b or between a protruding part 1b and a nut 3 or both of them. Then, a colored surface 6e is made on a protruding surface of, at least, a tapered part 6c located on each flat washer 6a. The conditions of fastening a bolt and a nut 2, 3 are shown by covering a colored surface 6e with each flat washer 6a after each flat washer 6a is buckled into flat by fastening a bolt and a nut 2, 3. The conditions of fastening the bolt and the nut 2, 3 can be easily checked by just looking at the colored surface 6e on the flat washer 6a.

摘要： PROBLEM TO BE SOLVED: To provide a swan socket welded joint which improves tensile strength of a weld zone by forming an inner groove on the end face of a socket body.
SOLUTION: This is a swan socket welded joint with which piping of tubular bodies is performed by welding tubular bodies 1, 2 with the welding ends inserted in the end part of a socket body 3. The end face of the socket body is removed from the outer to the inner peripheral face side of the end part to form an inner groove 4 on the inner peripheral face side of the end part of the socket body. Since a welding length for the tubular bodies is increased compared with the conventional swan socket welded joint that has no inner groove, the tensile strength of the weld zone is remarkably improved, which enhances durability and reliability of the weld zone connecting the swan socket welded joint and the tubular bodies.

摘要： PROBLEM TO BE SOLVED: To easily confirm a fastening state by sandwiching a seal ring by plural housings via a bolt and a nut, interposing a pair of disc springs having opposed projecting surfaces in layers, and buckling these in a plate shape. SOLUTION: An end part of a connecting tube 4 is pressed in both ends of a seal ring 5, a housing 1a of a coupling main body 1 divided into two parts is fitted to the seal ring 5, a projecting strip 1d is engaged with a recessed groove 4a of the tube 4, a bolt is inserted into a bolt hole 1c of a projecting part 1b, and a nut 3 is threadedly installed in a screw part 2a. At this time, a pair of disc springs 6a are previously fitted and installed in layers in a bolt neck part so that projecting surfaces are opposed, and the screw part 2a side is similarly formed. In temporary fastening, a coloring surface 6b of the disc springs 6a can be seen from outside, but when fastening a bolt and a nut 2, 3 by a tool or the like, the disc springs 6a buckle to become a plate shape, so that the coloring surface 6b is brought into close contact with the disc springs and becomes invisible from outside by regular fastening to thereby easily confirm a fastening state to prevent liquid leakage by forgetfulness of fastening and insufficiency.
