Easy
No specialized technology required.

  1. Easy to install. Not much time is needed to get the required skills.

    With the existing method, a high level of skill was required for installation such as cutting screw threads in a steel pipe. In contrast, the pipe expansion-type, O.N. Fitting does not require much learning. Anyone can easily perform the installation work by using dedicated pipe expansion machine. Quick and easy, by inserting an expanded pipe into the main body of the fitting and attaching a cap nut. Just a few hours of lectures is enough to start working.

    • Install the attachment.

    • Attach the cap nut to the yoke.

    • Insert the pipe all the way into the guide rod.

    • Turn the switch ON.

    • Check the expanded pipe with the limit gauge.

    • Put the expanded pipe into the main body of the fitting.

    • Temporarily tighten the cap nut.

    • Tighten with the nice wrench.

  2. Easy to avoid forgetting to tighten the cap nut! Safe, as tightening can be checked visually!

    To prevent “forgetting to tighten” the cap nut, a colored plate washer is attached at the part connecting the end of the cap nut to the main body of the fitting. If it is tightened correctly, the colored part of the washer is invisible. If it has not been tightened, the colored part of the washer is clearly visible, which easily prevents forgetting to tighten the cap nut. Also, the extent of tightening (“looseness”) can be judged from the colored part of the plate washer, allowing safety and stability of work to be secured.

  3. Easy work that just involves tightening with the pipe wrench.

    To tighten the cap nut, just tighten it with the pipe wrench. No need to use excessive force, and adequate tightening can be checked visually by viewing the colored washer. Also, if the special "Nice wrench" (50 Su and 60 Su) is used, the efficiency of tightening the cap nut is increased.

    • Expansion of large diameter stainless steel pipes (75 Su to 100 Su)

    • Expansion of small diameter stainless steel pipes (13 Su to 60 Su)

  4. Solve the human resources problem!

    No need to worry about lack of human resources. The expansion-type pipe work of O.N. Fitting is easy. No special skills are necessary, such as cutting the screw threads and use of fire. Also, as piping units assembled with O.N. Fittings and stainless steel pipe are lightweight, only a few workers are required.
