Infinite Fire & Mechanical test & inspect wet pipe sprinkler system, which includes gauges, system valves, the fire department connection, components & signs.
We will exercise control valves, & open the main drain valve to record static & residual pressures. This inspection includes a building walkthrough to visually inspect sprinkler piping, fittings, and hangers.
We’re known for our expertise with all types of fire sprinklers, including wet pipe, dry pipe, deluge and pre-action systems, and we have
the knowledge to determine which system is right for your property, design a system that fits your needs, build and install it in strict adherence to government codes and regulations.
Wet Pipe Fire Sprinkler Systems
Among all the fire systems in existence today, the wet pipe fire sprinkler system is the most prevalently used. It’s referred to as wet pipe because there is always water in the piping system that lead to the sprinklers.
This means there is no delay when the sprinkler is activated – the water is at the ready and releases immediately upon activation.
For property owners who experience a fire, the wet pipe sprinkler system doesn’t require much to get it back up and going.
In fact, most of these systems are designed so the water supply simply has to be turned off, replace any fused sprinklers, reinstate the protection, and turn the water supply on again.
Dry Pipe Fire Sprinkler Systems
While the wet pipe system is the most popular due to its ease of installation and maintenance, it’s not a perfect fit for all occasions.
Any structure where freezing is a possibility, dry pipe systems should be installed because a wet pipe system stands the chance of bursting should the water in the pipes freeze and expand.
Instead of being filled with water, the dry pipe system is filled with pressurized air or nitrogen. The air or gas will hold the dry pipe water valve in a closed position, preventing water from entering the pipes.
However, should a fire break out, the sprinklers activate and the air is released, taking pressure off the valve and allowing water to flow to the sprinkler heads.
Deluge Pipe Fire Sprinkler Systems
Every fire sprinkler system should be designed to fit the specific and unique needs of each individual structure. The deluge fire sprinkler system fits the needs of most high hazard industrial and commercial spaces.
These might include areas where high volumes and high capacity suppression is necessary to knock down flames and prevent further damage.
Power plants and chemical processing facilities are also common users of the deluge fire sprinkler system. Large spaces, such as aircraft hangars, are also prime targets for the deluge system.
The sprinkler heads are designed in an “open-type” fashion, which are attached to a dry pipe connected to the main water supply. Since many of the large spaces these systems are utilized are not heated during the cold winter months,
the dry pipe system is the best option, as it is impervious to freezing conditions, whereas a wet pipe system stands the risk of bursting should the water freeze.
Pre-Action Fire Sprinkler Systems
Pre-action fire sprinkler systems utilize a dry pipe system (in most situations) where water is not present in the piping system until fire triggers the valves to open and release water from the water supply, to the pipes and through sprinkler heads.
The pre-action system relies on an electrically operated valve controlled by an independent detection system.
A pre-action system is triggered in a two-step process. First, the detection system must be triggered by a developing fire, which opens the pre-action valve. It is at this point that the dry pipes are now filled with water. The second trigger involves the sprinkler heads themselves.
When a fire reaches a specific area, the sprinkler heads will detect it and allow the water to flow from the sprinkler head.
Water sensitive environments, like libraries, fine art storage areas, and data centers will choose the pre-action system for extra assurance that the products and equipment within are safe from accidental deployment of water from the sprinkler heads.
