This article attempts to fully explain to the reader all the concepts relating to types of Pipeline Strainers.
Strainer Valve
A piping system that enables the passage of fluids for refining purposes, filtering, or isolation from particles is known as a strainer valve. It also refers to any device which strains a fluid and works as a filter to prevent solid items from mixing in a flowing fluid. The reason why strainers are employed are to filter through unwanted components and guard the whole pipeline system.
Factors to Consider Before Choosing Pipeline Strainers
Dimensions: It is very important to select the appropriate dimensions. A larger than required size can result in the passage of unwanted materials that can affect the functioning of the gear. On the other hand, a smaller size can lead to a fall in the pressure that can hamper with efficiency.
Strainer Unit’s Size: The size should always be based on how many dirt particles the unit will collect and how much pressure the strainer can handle. Utilizing a strainer that is tiny will result in added difficulty in keeping the parts dust free. Problems relating to pressure drops can also be observed.
Expected Pressure Fall: Strainers protect components like pumps from unwanted materials. These pumps require a regulated pressure range to work properly. It’s important to figure out the strainer’s allowed pressure drop to ensure that its framework doesn’t cause problems.
Temperature and Pressure Limit: It’s important to determine the regulated pressure and thermo capability for all industrial strainer equipment. These specifications could be used in a broad spectrum of applications and may not meet the needs of specific protocol lines. It is very important to explain why each strainer is different from the rest.
Choice of Materials: The materials in the strainer must match the materials in the pipe. This information is usually found in the same pipe class as in the Material Brochure. They usually cover things like the strainer body and cap. The substance grade while manufacturing the component should be at least similar or better than the rest of the body.
Role of Strainers in Piping System
A pipe strainer is equipped to screen through media, isolating bigger pieces from smaller pieces, and separating the fluid from flow particles in the media that are in the tube. Dirt is deposited along with the flow of media.
Strainers are supposed to nullify substances that could potentially affect the pipe system. They cut down on the time and money it takes to fix broken things. The remaining parts of the system are safe because harmful particles are now out of the way.
Sectors That Employ Pipeline Strainers
They are seen next to valves, compressors, and pumping systems. Piping systems become much more powerful and effective If strainers are used. They can also be used when the medium is denser or has toxins to be processed.
A Strainer Can Be Used in a Wide Range of Industries:
● Chemicals Industry
● Water Treatment
● Food Sector
● Energy Sector
Selecting Strainers Like An Expert
Industrial strainers manufacturers roll these products out in an array of different dimensions. Putting some effort into determining how to select the correct strainer ensures that the operation continues smoothly.
Flow Velocity: The rate of flow of media is important to understand. Reducing flow profile has a direct effect on the system. If a material is dense, it would be associated with slate flow rate. A denser media can be related to pressure drop.. The expected pressure loss should be determined before using. Pressure drop statistics on the web can be used to calculate the pressure loss across the strainer.
Open Area Proportion: It is a mechanism designed to understand the service intervals of a pipeline system. It is influenced by the degree of pressure loss within the system. It is an indicator of when the netting should be washed. A blocked filter significantly reduces pressure. It implies that the media is congested with particles.
Mesh Dimensions: Mesh size is usually measured in microns but some people also measure it in mesh number i.e., number of depressions per inch. This value depends upon factors like heat ,pressure and nature of material.
Different Kinds of Pipeline Strainers (With Applications)
Y-Type Strainers
Constructed like a ” Y ” , this strainer is very effective because there are minimal chances of the medium altering its path while it is heading towards the filter. The structure consists of a net and a wire straining piece. Due to their efficiency, they are mostly employed in clean medium mechanisms. For example, they are employed with solenoid valves because they are very reactive to dust and require a clean medium to work. Therefore they are used in systems where there exists a high possibility of system failure due to inculcation of foreign elements.
Advantages: Simple Cleaning, Variety of perforations or meshes or combos, Perpendicular and parallel mounting possible.
Applications: Helps with gas natures like vapour and LPG etc
Basket Type Strainers ( T-Type )
Unlike Y type strainers, the t-type filter through larger chunks of foreign particles and are used in high maintenance piping systems. Due to this factor, the t-type has a bigger filtering area than its counterpart- the Y type.
T-type has a lower pressure drop than the Y-type. Additionally, a basket strainer may hold more debris.
Installed in linear piping systems, a basket strainer is required to isolate unwanted particles from entering the stream. They are strategically placed before control appliances like traps and pumps so that unwanted debris can be halted before hitting essential equipment. They can have an isolated installation or can be coupled or even possess multiple strainers together for efficient working.
Applications: If unwanted debris results in malfunction of the system, this type of strainer offers an opening so that engineers can access and clean the equipment. Also, when installed on boilers T type strainers possess a vapour nullifier to nullify the excessive vapour.
Twin Basket Strainer
Duplex basket strainers are ideal for continuous processes where maintenance is tricky.
Each filter has two baskets, and a switch ensures that while one basket is being treated, operations are still being carried out in the other.
The system is continuous. By employing a switch, the chamber that is required to be cleaned goes into maintenance whereas the other automatically is put into operation without any pressure hike. This is made sure by using a screw for decreasing the pressure. Maintenance fluid is used and compressed air is used to blow dry the chamber.
Temporary Strainers
In cases where a more economical
approach is required, the more cost-effective solution is to use temporary
strainers. Installations are usually designed between tube flanges. There are
three basic types of temporary strainers, and each one has a simple design.
● Truncated
● Conical
● Flat
Basket strainer suppliers often design them to
have higher postures, whereas this temporary strainer is generally lower. In
addition, the disassembly of the parts of the pipeline may make maintenance and
cleaning of these items more tedious. Also, if the strainer is under fluid
pressure, it can bend.
Special Type Strainers
Jacketed Strainers: Due to additional coating of cast metal, this strainer is utilised in operations needing stability.
Wide Differential Strainers: The strongly welded mesh screens allow them to take on high pressures.
Magnetic Strainer: The strainer is structured strategically along the location of the medium. The path is then levied around the field created by the strong magnets. This is how the ferrous particles get attracted towards them and get isolated from the medium.
Large Capacity Basket Strainers: Due to their wide baskets, they have over the top straining strength. The construction prevents blockage in case of dense media.
Micronic Strainers: To filter particles of the range of four to five microns. These strainers use a tiny mesh to filter fine particles. Example: Filtering water from oil.
Offset Strainers: They are mighty efficient for pumps near the ground. These strainers offer low contamination possibilities.
Reducing Strainers: Used instead of the reducers to control pressure drops.
Types of Screens in the Piping Process
Mesh Screen: Thin Wires on top of a Perforated Screen. Effective in filtering particles in the range of 0.07mm.
Perforated Screens: Filtering ranges from 0.8mm to 3.2mm. Holes are punctured into linear screens and then rolled for two ends to connect.
Materials Employed in Pipeline Strainers
● Plastic Strainer: For cases where
pressure and temperature are extremely low.
● Bronze: For cases where the fluid is
saline water
● Cast Iron: Popular for working in low
pressure, temperature and affordability
● Carbon Steel: For possibilities of
fire, high pressure and temperature.
● Stainless Steel: Employed in places
where erosion is an issue.
Difference between Strainers and Filters
Filters have a wide range of industrial applications, whereas a strainer is a type of filter.
Filters are employed to isolate substances. The thing they actually do is to stop media from passing downstream.
Particles measuring around one mm can be separated by the use of filters. The only way to remove minute molecules from mediums that are not solid is by using strainers.
Unlike filters, strainers’ mechanisms can be reused numerous times, whereas filters’ straining mechanics are only used once.
Another distinction is the ability to resist. Most times, strainers are designed as such to allow a less resistance to medium flow. Also, maximum strainers offer minimum pressure reduction when compared to strainers working on thicker mediums.
Unwanted foreign particles will surely damage the equipment along the medium’s flow unless controlled by the strainer. Simultaneously, particles can be separated from the medium by employing a filter.
Difference between Common filters and Industrial Filters
But, there lies a massive variance between the standard filtration systems and those used in manufacturing processes. Although small in size, unique filtration systems are very advanced in design. Their features include pressure variation adaptability and low maintenance cost.
They have a tremendous particle restricting potential. Industrial strainer Manufacturers design different sizes in accordance with additional needs. Their size is measured in NB, which is primarily a function of the device’s radius. Popularly they are designed to filter particles greater than 5 microns
