Welding Myths (Leak Trouble Edition) [Piping Maintenance]

Ihara is a pioneer of the flame-free construction method with over 80 years of history.

Piping still primarily relies on "welding construction." I believe this is due to the "welding myth" that welding is easy, reliable, and safe. However, there are various challenges associated with piping welding: - Decrease in skilled workers due to aging - Variability in quality - Time and effort required for preparation and post-processing In response to these challenges, we propose optimal methods tailored to fluids and applications using products like the "Kui Komi Joint" (length-adjustable joint) and "Oi-sugu Flange," which can be easily and quickly implemented by anyone, anywhere. This achieves approximately a 76% reduction in construction time compared to welded piping. *For more details, please download the PDF or feel free to contact us.*

basic information

【Features】 ○ Reduces piping labor by eliminating the need for threading, welding, flare processing, and brazing. ○ Allows for thinner pipes and easier bending due to the absence of threading and welding, resulting in fewer fittings used and lighter, more compact equipment. ○ Ensures complete reconnection even after repeated disassembly and reassembly. ○ Usable over a wide temperature range due to metal contact seals that do not use sealing materials like O-rings. ○ Suitable fitting materials such as carbon steel, stainless steel, and brass can be selected based on the fluid used and external environment. ○ The envelope part of the sleeve allows for precise alignment of the piping, significantly reducing issues caused by misalignment, which has traditionally been the main cause of oil leaks. ○ Improved vibration resistance due to the slotted envelope part. ○ Fatigue strength improved by over 20% compared to conventional NS-type embedded fittings, reducing pipe damage and nut loosening caused by piping vibrations. ● For more details, please contact us or download the catalog.
