Dry pipe sprinkler system trip tests include several dry sprinkler components.
Dry pipe sprinkler system components.
Following operation or testing dry pipe sprinkler system piping is drained but residual water collects in piping low spots and moisture is also retained in the atmosphere within the piping.
Dry pipe sprinkler system ii.
This air holds a remote valve known as a dry pipe valve in a closed position.
A dry system as defined in nfpa 13 is a sprinkler system employing automatic sprinklers that are attached to a piping system containing air or nitrogen under pressure the release of which as from the opening of a sprinkler permits water pressure to open a valve known as a dry pipe valve.
This air holds a remote valve known as a dry pipe valve in a closed position.
Dry pipe fire sprinkler system.
So before jumping into the trip test a professional must take time to assess the equipment and factors that might impact the performance and accuracy of the test results.
Located in a heated space the dry pipe valve prevents water from entering the pipe until a fire causes one or more.
Dry pipe fire sprinkler system.
Dry pipe sprinkler system.
Nfpa 13 also regulates the size of a dry sprinkler system controlled by a dry valve.
Additional dry system components.
The pressurized air or nitrogen in the pipes prevents the water from flowing.
Flow control pressure regulation.
Figure 4b figure 5 figure 6 figure 4c.
Once a dry pipe valve is tripped there s no going back to document previous static pressures.
System components requirements viking dry pipe valves must be installed in the vertical position only.
This system works well in areas that have temperatures that fall below 40 f since there is no water in the pipes so they do not have the risk of freezing.
Read this carefully before starting.
This moisture coupled with the oxygen available in the compressed air in the piping increases internal pipe corrosion eventually leading to pin hole leaks or other.
Connections are provided on the system side of the valve for the air supply figure and for a valve room sprinkler figure 6.

Dry pipe fire suppression.
The water then flows into the piping system and out.
Viking cpvc piping system.
15 3 3 where dry sprinklers are connected to wet pipe sprinkler systems protecting insulated freezer structures the clearance space around the sprinkler barrel shall be sealed.
A dry pipe sprinkler system is one in which pipes are filled with pressurized air or nitrogen rather than water.
