NiroSan® Stainless Steel
316 & 316(L) with Molibden inside
System description
The piping system consists of premium NiroSan® stainless steel press fittings with an EPDM (ethylene propylene diene rubber) moulded sealing ring and NiroSan® stainless steel system pipes according to EN 10312. Please check also SANHA® web page for detailed information and certificates
Wide Range of Application
All NiroSan® press fittings are made from the premium stainless steel type 1.4404 / AISI 316L (for pressing components) and 1.4408 (for precision cast threaded stainless steel components). The material 1.4404 contains at least 2.3 % molybdenum, yet less carbon than the conventional type 1.4401. For this reason material no 1.4404/316L is a superior material with higher corrosion resistance than standard stainless steels.

Certified quality
The NiroSan® press system and its components are certified in accordance with the rules and regulations of all important national and international certification bodies such as DNV-GL, ABS, RINA, L’LOYDS REGISTER, WRAS, KIWA, DVGW and many more.
Silicone free version
All press fittings and pipes of this series are also available in a silicone free version with an EPDM O-ring (series 9000 SF). This is especially useful in industrial production which require silicone-free environments and media and ensures that no silicone is introduced by the piping system.
