Ensuring that an industrial pumping station conforms to standards is crucial in any pipeline network connection. Industrial/domestic pipelines all come with numerous challenges that need to be tackled from the onset.
When pumping stations of pipelines are properly set-up, it guarantees increased productivity and also saves a company a significant amount of revenue that can be lost as a result of damages caused by poor pipeline network establishment.
For a company to be able to achieve maximum benefits from its pipeline connection system, its pumping station must have a surge anticipation valve that is well fitted in accordance with the application standards.
Surge anticipation valves are designed to project dangerous energy accumulation levels that can arise from a sudden change in flow velocity and relieve it out of the pipeline. These often hinder surge pressures in pipelines from rising above steady pumping pressure in any event of a water hammer.
When the pumping systems of pipelines are allowed to run gradually in each state of starting or stopping, pressure surges cannot go beyond the steady state. However, in an event of power failure, sudden stopping of the pumping station motors can cause water hammer resulting in severe damages like explosion, dislodgements, injury to workers and damage to other equipment.
Setting-up a Robust Surge Anticipation Valve system
When setting-up a surge anticipation valve system for your pumping station, you must take note and apply the following rules,
Ensure that there is enough space around the valve assembly for future maintenance and adjustments.
Design the installation of the Surge Anticipation Valve on a T-branching off the pipeline, downstream from other check-valves.
For the purpose of future maintenance, you should install Isolation gate valves upstream (and downstream if not releasing to the atmosphere).
Before installing the valve, you should flush the pipeline to ensure that clean fluid flows through the valve.
Use the lifting ring provided on the main valve cover for installing the valve.
Install the Surge Anticipation Valve in the pipeline, it will help the flow direction arrow points to the actual flow direction of the system.
It is recommended that Surge Anticipation Valves should be upright and horizontally installed for best results.
Set up a 0.5 – 2 inches female threaded “Remote Sensing and Operating Pressure Port”, which is made up of a cock-valve and a filter, located on the main discharge line, downstream from the pumps manifold, where there is less flow velocity.
Install a 0.5 inch female thread adaptor at the valve-side end of the control & sensing tube.
Pull the 0.5 – 2 inches tube, from the “Remote Sensing & Operating Pressure Port”, to the valve. Ensure tube protection by installing a covered cable-canal.
Install a very strong fixed effective tubes route.
When you finish all installation set-ups, you should carefully inspect to correct any damaged pipings, tubings, or fittings.
