The strainer is a filter for impurities both in the form of solid, liquid or gas. This filter is usually used in pipelines that function to filter out impurities in the flow so that the flow to be processed or the process results are of better quality.
How the Strainer Works in a Hydrant
The way the strainer works is very important, so the fire hydrant system can work properly. As we have already known, that the fire hydrant system works with each other, so all components must be in the system, including the strainer.
Keep in mind that the installation of a strainer should not be reversed, note the direction of the arrow that is in the body of the strainer.
How the Strainer Works on the Suction Pipe
Strainer is one component that is installed on a suction pipe or a water suction pipe, either in a fire hydrant system or a fire fighting team car. Suction pipes used to suck water, sometimes get a source of water that is not necessarily clean, such as river water or ditches.
Linkage Between Water Pressure and How the Strainer Works
The strainer component in the fire hydrant system is also closely related to water pressure. The strainer works to keep the dirt from entering the fire hydrant pumps.
Because for example there is no small object in the fire hydrant pump, the hydrant pump can be damaged. So, the function of the strainer to filter water is very important.
In addition, if the water pressure in the fire hydrant piping system is not normal, you can check the strainer or suction pipe tip. If there is dirt or soil deposits, either on the strainer or suction pipe, you can clean it so that the pressure on the fire hydrant pipe can return to normal.
The types of filtering equipment can be divided into:
1. Type T. (picture to the right)
This type is used in general to expand space and reduce pressure on the pipeline.
2. Type Y (image to the left)
3. Temporary type
4. Flat type
Steam Trap (Steam Trap)
Steam Trap is a tool that is used to get rid of water from steam, where this water is useless and will even provide resistance to steam flow or can cause other losses. This steam trap is placed in the lowest place of a pipeline or installed in a pipe bag called Drip Leg. Installation of Steam Trap also should not be reversed, note the direction of the arrow on the body (casing). If there is no arrow direction then ask the engineering or related parties.
Steam Trap looks like this:
Ways of working:
1. Steam Trap on the lowest pipeline area where it is considered water may have hung on a pipe bag (Drip Leg)
2. This steam trap will empty water into a steam system that has a lower pressure
3. The trap system that is enclosed in emptying water uses valves on the side of the trap.
4. Use a filter if this trap system has not used it. Install the test valve for disposal during start up testing.
Vent and Drain
Vent is a gas, air or water vapor removal device. while the drain is a liquid discharge device. In the disposal system contained in the pipe or equipment, Vent and Drain in how it works can be divided into two parts, namely: work and not work.
For Vent and Drain grouped works, it is intended that this equipment is used in pipes or equipment in a state of working for a long time or continuously.
Grouped Vent and Drain do not work only used at certain times, for example when testing, start up or shut down.
For Vent and Drain installation, piping engineering group must first be approved, both regarding its use and placement. In addition, it must also be noted that plugging in the valve such as a plug or blind flange.
For special things, namely the flow that has a high level of danger, placement and use must be really calculated and controlled implementation.
