Different Types Of Strainers In Pipeline
Are you looking to learn about the different types of strainers used in pipeline systems? If so, you’ve come to the right place. Understanding the different types of strainers and their applications can help you choose the right strainer for your pipeline system, ensuring that it functions optimally while minimizing maintenance costs.
Working Pressure and Temperature Ranges of Strainers
The first thing to consider when choosing a strainer is its working pressure and temperature ranges. Strainers with an open area ratio of two to four times the cross-section of the inlet pipe are recommended. Additionally, the critical velocities of the straining medium should be known, as the higher the screen velocity, the larger the differential pressure drop.
What is a Strainer Valve?
A strainer valve is an important piece of equipment that protects a pipeline system by removing unwanted debris that can clog up components and damage equipment. The size of a strainer’s mesh is determined by the size of the particles that need to be filtered, with larger mesh sizes being able to filter larger particles. Mesh-lined strainers are the most common type and can achieve fine straining, but are more expensive.
Basket strainers are used to protect downstream equipment by preventing solids and debris from entering the system. When selecting a basket strainer, it is important to consider the type of liquid and pressure that will be encountered. These are the most commonly used in food and beverage processing.
A Y-type strainer is characterized by two metal plates held together by bolts or gaskets, with a perforated sheet and wire-mesh lining. It is used to filter liquids through pipelines and can work in both vacuum and suction conditions, but has a lower dirt-holding capacity and requires more frequent cleaning.
Temporary strainers are used to remove debris from pipelines during the startup of new pipelines or during the cleaning and modification of existing systems. They are designed to function at high differential pressures and are installed upstream of pumps and other equipment to protect them from debris and foreign objects.
Special Type Strainers
Special type strainers are designed to remove solid matter from a pipeline and feature a perforated metal mesh as the straining element. They are used for specific applications, such as wide differential strainers, jacketed strainers, magnetic strainers, micronic strainers, offset strainers, and reducing strainers.
In conclusion, understanding the different types of strainers and their applications is important in choosing the right strainer for your pipeline system. Basket strainers, Y-type strainers, temporary strainers, and special type strainers all have specific uses and are made of different materials. By selecting the right strainer, you can protect your downstream equipment, minimize maintenance costs, and ensure your pipeline system functions optimally.
