O.N. Fitting
1. Unique pipe expansion structure
- Having a design that is highly resistant to tensile and bending load and earthquakes.This structure enables changes layout, disassembling and reuse of joints.
- Tightening condition of the cap nut can be checked visually to prevent them from not being tightened due to forgetting.
- You do not need to worry about pipes coming off. Pipes are expanded in a convex shape and cap nuts are used to prevent from coming off.
- When pipes are expanded, the tolerance of the pipe is corrected and uniformed compressibility of rubber sealing material can be achived.
- Pipes have a tolorance in accordance with standard, it causes pipe sizes differ slightly. The pipe expansion process decrease the tolerance and correct slight oval disortion.
2. No need of heat, flames or oil
Since flames are not required to install and repair work, this system ensures safe operations. In addition, installation can be performed without using oils and washing can be reduced.
3. Light, enabling easy transportation and installation
Having a high corrision resistance, O.N. Fitting system does not require margin for corrision. Moreover, since it has high strength, it can be produced with thin wall thickness.Weighing only about one-third the weight of carbon steel pipes in system, easy to transport and install.
4. Speedy pipe expansion
When compared to threading, pipe expansion can be done in much shorter time.
5. High Level of hygiene
Stainless steel, free from red water generation due to corroision, and blue water generation due to copper io elution, is used.
6. Gentle to the environment, long-lasting and economical stainless steel
Stainless steel is the most appropriate material for recycling and stainless steel pipes have a long life span(life expectancy)
O.N. Fitting can be used for cold water, hot water, cooling water, high temperature water supply pipes, compressed air and steams.Temperature is from 0 to 100 degree celsius and up to 20 bar.
EPDM rubber sealing material is set inside of fitting body from 15mm to 54mm sizes.
