How does the 316 Stainless Steel No Weld Pipe and Fitting System work exactly?
The No Weld Stainless Steel Press Fit piping system is really very simple. You simply measure and cut the tube to the length required and de-burr. You then choose the desired fitting (from a range of over 60) and slide the fitting onto the tube. Once you are happy with the fitting position, simply apply pressure via the Pressing Tool to ensure tightness between the tube and the fitting. The "O" ring creates the pressure seal. The tool is designed to apply the correct pressure to the fitting and automatically releases once the cycle is completed. The task is totally finished in a few seconds.
How long does the "O" Ring last within the fitting?
As there is no mechanical wear, the “O” Ring is only potentially susceptible to chemical wear. As such it is important to select a rubber that will not chemically react with the fluid/gas being transported. By avoiding any chemical reaction with the o-rings, then the piping system is expected to last equivalent to other piping systems. The No Weld fittings are covered by a standard 20 year guarantee when installed following manufacturers guidelines. The standard “O” ring supplied is EPDM. This rubber is particularly resistant to ageing, ozone, heat, as well as to various chemicals, including conditioners normally used for drinking water and for cooling systems. Systems that are to transport petrochemicals (fuel oils, lubricants, etc) are supplied upon request with NBR "O" ring's. HNBR "O" ring's are supplied for gas installations. It is important to ensure that the correct "O" ring is used in each application. With the correct "O" ring installed Non Weld Pipes and Fittings have been in service for over 30 years across the world in a broad range of applications without "O" ring failure. Due to this fact and the benefits gained, the use of Non Weld Pipe and Fittings installations continue to grow significantly in Australia and around the world.
Why use 316 Stainless Steel No Weld Pipe and Fittings?
