On-Site Flange
Non-Skill Work Series

■ Features of On-site Flanges
The 『Ｏn-Site Fｌａｎｇｅ』 enables piping connections without welding. By utilizing a dedicated tightening device onsite, even individuals without specialized skills can easily and reliably set up connections. No welding work allows
for quick performance of piping maintenance tasks. This product achieves welding-equivalent strength throughswaging the sleeve onto the piping. Pre-welding fire prevention measures are un-necessary, and processes likepost-weld acid washing are not required. This significantly reduces downtime for facility operation and facilitateseasy recovery during troubleshootng.
Feature１ Sleeve securely swages onto the pipe

Swaging jigs and procedures for sizes 15A（1/2B）and 20A（3/4B）

Swaging jig appearance① Insert collar/sleeve into the tube until itreaches the bottom, then mark at theboundry between the components.

③ Pass only 3 bolts through the flange, and using a wrench lightly screw
them into the threaded holes on the main body of swaging fixture ofmatching sizes, until they contact the stopper.

②Turn the push screw to the left andbring it back in front.

④Insert Collar/Sleeve through the gap.

⑤ Screw in the fourth bolt following
the same procedure as in step ③.
⑥Turn the push screw to the right and finger‐
tighten it until there is no rattling between theparts. At this point, the cores of the parts
naturally align.

⑧ Firmly grip the handle and tighten
the push screw with an impact wrench※ until it no longer advances.

⑨ After tightening, loosen thepush screw and remove the 4 bolts.
The photo shows the completely
tightened state.

⑦Insert the tube to thebottom.

⑩ Finally, confirm that the mark madein step ① has not shifted.

※Tightening torque 300N・m〜600N・m、Socket size 19mm（Hexagonal width of push screw 19mm）

Swaging jigs and procedures for sizes 5A（1/2B）〜50A（2B)① Close the relief valve of thehydraulic jack.

Swaging jig appearance（Air Hydraulic Jack※）② Attach a fixture corresponding to thetube size to the main body of theswaging fixture.

※Operating air pressure
0.5MPa〜0.9MPa③ Insert the flange into the tube, then slide Sleeve/
Collar all the way in. Mark at the boundary between
the components.

④ While supporting the components and preventing themfrom falling, insert the tube into the U‐shaped flange, reaching
the back.
Place it on top of the hydraulic jack. In this position, the core of
the jack and the components align.

Air switch⑤ While supporting the tube, turn on the air
switch and jack it up until it no longer rises.

⑥ Gently open the relief valve of the hydraulic jack, return thecylinder to its original position, and remove the tube assembly.

⑦ Finally, confirm that the mark made in step ③ has not shifted.
