Selecting A Slurry Service Provider

It is not as easy as it seems to move slurries. It is indeed a problematic fluid to run if you do not have the right set of equipment. Slurries can contact solids, corrosive, abrasive and what not. It is present everywhere, from paper mills to wastewater plants and even mines. For cleaning, slurries contact Dual Valves Australasia who is an expert in helping companies out with slurry disposal. According to www.pipingguide.net/2013/10/ball-valves-types-construction.html equipment with a specific type of construction properties specialize in treating sludges. In fact, selecting a piece of equipment to move the slurry is a task in itself. Process pieces of equipment can get damaged within a numbered use from running mud.

Selecting a valve for slurry application is an expert’s task. One cannot do it right unless he or she has worked with different kinds of slurries formed in different types of industries. Selecting a valve depends on two factors. The first element is the service a person is expecting from it. Secondly, the cost a company is willing to pay for the device. Valve selection can differ depending on the type of slurry to be treated. However, do not let cost become the deciding factor in this case as sludge can be a huge burden to deal with when the equipment is not right.

It will merely consume a lot of time and end up damaging the valve after a few use. For low pressure and low-temperature slurries, companies typically use pinch valves or diaphragm. On the contrary, for high pressure and temperature slurries, more specialized valves are used. Most standard plugs that are meant for everyday liquid application will not last if used to move slurries especially the ones with abrasive. Dedicated caps will be needed for this purpose which will be decided upon depending on many different factors.

Factors could be temperature, slurry content, pressure and heavy or light duty.

Some companies use made to order valves for the kind of slurries produced in their factories. The valve must be strong enough to bear the wear caused due to the corrosive or abrasive particle in the mud. Most importantly, the valve gates must be made of abrasion and corrosion resistant material.

The valve must be adequate to prevent friction during operation. Again, this depends on the nature of the slurry. Whether it will be metal to rubber or a metal to metal contact is also a deciding factor. The sliding gate design will depend on the nature of the slurry.

The valve must be made in such a way that it tolerates pressure. Closing of a valve can be challenging for any person, if the material of the valve is not built to withstand pressure. Especially if a solid material is passing through the valve, closing it can be a challenge.

These were only a few properties to entail that will affect your valve choice. There are other minute factors for consideration, such as the flow rate, the particle size in the slurry, composition, etc. It needs a lot of calculation to find out the right dimensions of the valve and its internal parts.
