A standpipe is a type of rigid water piping which is built into multi-story buildings in a vertical position to which fire hoses can be connected, allowing manual application of water to the fire. Within the context of a building or bridge, a standpipe serves the same purpose as a fire hydrant.
Four types available:
1. Solid Head Standpipe with handle and without shut-off.
2. Swivel Head Standpipe without shut-off.
3. Swivel Head Standpipe with screw down valve.
4. Swivel Head Standpipe with British Standard BS336 connection.
Laying a firehose up a stairwell takes time, and this time is saved by having fixed hose outlets already in place. There is also a tendency for heavy wet hoses to slide downward when placed on an incline (such as the incline seen in a stairwell), whereas standpipes do not move. The use of standpipes keeps stairwells clear and is safer for exiting occupants.
Standpipes go in a direct up and down direction rather than looping around the stairwell, greatly reducing the length and thus the loss of water pressure due to friction loss. Additionally, standpipes are rigid and do not kink, which can occur when a firehose is improperly laid on a stairwell.
Standpipe systems also provide a level of redundancy, should the main water distribution system within a building fail or be otherwise be compromised by a fire or explosion.
More information on Hydrant Valves
A Fire Hydrant Valve is a pipe fitting that help to regulate, direct or control the flow of fire suppressing agents by opening, closing or partially obstructing passageways in the hose connectors. Non-return valves stop the fire suppressing agent from flowing in the wrong direction.
Fire hydrant valves are made from the finest materials in the industry. With the hose attached to the fire hydrant, the valve can be opened to provide a powerful flow of water to extinguish a fire.
Fire hydrant valves provides access to water supply for the purpose of fighting fires. The water supply may be pressurized or unpressurized. Every hydrant has one or more outlet to which a hose may be connected.
Most fire hydrant valves are not designed to throttle the water flow; they are designed to be operated full-on or full-off. The arrangement of most dry-barrel hydrants is for the drain valve to be open at anything other than full operation. Usage at partial-opening can consequently result in considerable flow directly into the soil surrounding the hydrant, which, over time, can cause severe scouring. Where a hose has a closed nozzle valve, or connects to a fire truck or closed gate valve, one must always attach the hose to the hydrant before opening the hydrant’s main valve.
