SANHA®-Therm Industry (series 28000) | Carbon steel

SANHA-Therm Industry

The SANHA®-Therm Industry installation system consists of tried and trusted SANHA®-Therm Industry system press fittings with a red moulded FKM (fluoro and perfluoro elastomer) sealing ring for high temperature applications and SANHA®-Therm carbon steel system pipes according to EN 10305-3.

The carefully manufactured installation system and its components offer a very attractive economical solution for closed heating circuits. At the same time, SANHA®-Therm Industry is exceptionally well suited for compressed air and fire extinguishing systems according to EN 10346 (DZ version). The variant "Contiflo" on the other hand offers hot-dip galvanized unalloyed steel system pipes (E195) according to EN 10305-3 which allow an especially easy deformation. Our C-Steel system is also available in a special LABS* free version (series 27000).

Carbon steel pipes and fittings require special care and treatment in terms of corrosion protection and can therefore only be used when the specific SANHA installation requirements are followed. These can be ordered at or  01628 / 81 92 45.

Please note that the pressing of sprinkler systems requires a special high-pressure sling.

SANHA®-Therm Industry system press fittings are labelled with the red letters „HT“ printed on the outside.

*LABS = paint wetting disruptive substances

Fast installation, no risk of fire

The connection with stainless steel pipes by cold pressing enables a fast, time-saving installation and eliminates the risk of fire during the process. NiroSan® installation systems are therefore ideally suited for renovation work. 

High corrosion resistance

The premium stainless steel type 1.4404 (316L) and the exceptionally smooth, passivated surface of pipes and fittings lead to an excellent corrosion resistance.
