Twist-in piping / The transformation of the welding myth

Ihara is a pioneering manufacturer of the fireless construction method with over 80 years of history.

Piping still primarily relies on "welded construction" and "threaded piping." I believe this is due to the "myth" that it is simple, reliable, and safe. However, there are various challenges associated with "welding" and "threading" in piping, such as: - Decrease in skilled workers due to aging - Variability in quality - Time and effort required for preparation, post-processing, and dimension alignment In response to these challenges, "screw joints" do not require threading, welding, flaring, or brazing, which reduces the labor involved in piping and allows anyone to easily and quickly use the product anywhere. *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. ○ Can be used over a wide temperature range due to metal contact seals that do not use sealing materials like O-rings. ○ Allows for the selection of appropriate fitting materials such as carbon steel, stainless steel, or brass 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. ○ Compared to conventional NS-type embedded fittings, fatigue strength has improved by over 20%, reducing damage to pipes and loosening of nuts caused by piping vibrations. ● For more details, please contact us or download the catalog.
