The Original GS-37° Flare Flange System
The reliable GS-37˚ Flare Flange System is of the highest quality and is fast and easy to connect. The cost efficient system is completely leak-free, with high joint integrity. Its connecting method allows piping systems with workings pressures of up to 420 bar and pipe sizes of up to 90 mm to be assembled without welding.
The GS-37˚ Flare Flange System can also be utilized for low pressure (< 50 bar) piping systems for pipe sizes from 25 to 273 mm. GS-Hydro’s flaring technology is fast and completely clean. In the flaring process the end of the tube is clamped into an in-house developed flaring machine where a conical rotating tool flares the pipe end into a dye. The flange is installed onto the pipe prior to flaring. The assembly is done by placing a flaring cone on both the flared pipe ends with a seal in-between. The flanges are then tightened together to complete the connection.
As There is no welding involved there is no need for post-weld cleaning, x-raying or other inspections. Installations onsite are very quick and cost efficient due to the flexibility of the GS- 37˚ Flare Flange System
