Preguntas frecuentes

Am I allowed to bend connection pipes?: It’s preferrable not to bend connecting pipes and use the appropriate elbows to install the piping with the desired layout.

If necessary it’s possible to bend the pipes if the correct bending radiuses are chosen (minimum is 4x the pipe diameter) and the correct tools are used (the correct tools do not alter the cross section of the pipes).

Bending of stainless steel is allowed only in case of heat-annealed pipes.
What’s the difference between an “open” and a “closed” circuit?: A “closed circuit” (often referred to as “closed loop”) shows no possible risk of increasing of the inside Oxygen/air content since is running always with the same water.

“Open circuits” run using an always-changing fluid so Oxygen/air is continuously flowing through the system.
What’s the difference between a “dry” and a “wet” sprinkler system?: Wet sprinkler systems are always filled with water in pressure. In case of fire a thermal-activated sprinkler nozzle sprays water over the flames to cool the area. Dry systems act similarly but the pipes are constantly filled with pressurized air instead of water.
