Selection and Applications of Pipe Strainers

Principle requirements for selection of pipe strainers 
A pipe strainer is a small device that removes a small amount of solid particles in the liquid, which can protect the normal operation of the device. When the fluid enters the pipe strainer's drum with a certain pipe strainer mesh, its impurities are blocked, and the clean filtrated fluid is discharged from the pipe strainer's outlet. When a pipe strainer needs to be cleaned, just take out the detachable strainer drum and reinstall it after cleaning.
 
1. The inlet and outlet diameter of the pipe strainer
In principle, the inlet and outlet diameter of the pipe strainer should not be less than the inlet diameter of the matching pump, which is generally the same as the inlet diameter of the pipe.

2. Selection of nominal pressure
Nominal pressure should be determined by the pressure rating of the pipe strainer according to the highest pressure that may appear in the pipe strainer and pipe.


3. Selection of the mesh
The selection of the mesh of the pipe strainer mainly considers the particle size of the impurities to be intercepted, which is determined according to the process requirements for the flow path.

4. Materials of pipe strainers
The material of the pipe strainer is generally the same as that of the connected process pipeline. For pipes with different service conditions, you can consider choosing a pipe strainer made from cast iron, carbon steel, low alloy steel and stainless steel.

5. Calculation of the resistance loss of the pipe strainer
The water pipe's strainer has a pressure loss of 0.52 to 1.2kpa under the general calculation of the rated flow rate.
 
Applications of pipe strainers
1. Stainless steel pipe strainers
Stainless steel pipe strainers are widely used in pipelines conveying steam, air, water, oil and other media, which are to protect various devices such as water pumps and valves from blockage and damage caused by impurities like rust and welding slags in the pipeline system. Stainless steel pipe strainers have advantages of having good dirt resistance, convenient sewage discharge, large flowing area, small pressure losses, simple structure, small sizes and light weights. Stainless steel pipe strainers are made from stainless steel, which makes them have good corrosion resistance and a long service life.
 
2. Y pipe strainers
A Y pipe strainer is an indispensable filter device in the piping system for conveying media. Y pipe strainers are usually installed at the inlet of pressure reducing valves, pressure relief valves, and other devices to remove impurities in the medium and make valves and devices use normally. Y pipe strainers have the characteristics of advanced structure, low resistance and convenient sewage discharge.
 
3. Y pipe strainers with flexible expansion joints
The Y pipe strainer with the flexible expansion joint adopts a new design, which combines the Y strainer with the expansion joint. The structure is simple and it is easy to use. The Y pipe strainer with the flexible expansion joint solves the problem of inconvenient installation on the fixed pipeline caused by the different lengths between the flanges of various standards, which is mainly used for water supply and drainage piping in high-rise buildings, multi-storey buildings or factories. It is usually installed at the inlet of pressure reducing valves, pressure relief valves and other major devices. The impurities in the pipeline can be removed after installing the Y pipe strainer with the flexible expansion joint so as to ensure the normal use of valves or devices.
 
4. Basket pipe strainers
A basket pipe strainer is a small device that removes a small amount of solids contained in the fluid, which can not only guarantee the normal operation of compressors, pumps, meters and other equipment, but also improve purity of products. Therefore, basket pipe strainers are widely used in petroleum, chemical, chemical fiber, medicine, food and other industries. The basket pipe strainer is composed of a shell, a discharge cover, a filter element, a filter and a bolt.
 
5. T pipe strainers
T pipe strainers are widely used in pipelines with various media such as steam, air, water, oil, etc. to protect various equipment like pumps and valves from blockage and damage due to rust, welding slags and other debris in the pipeline. T pipe strainers manufactured by UNIQUE VALVE have the characteristics of good dirt resistance, convenient sewage discharge, large flowing area, small pressure loss, simple structure and small sizes. The T pipe strainer is also made from stainless steel, which has good corrosion resistance and a long service life. T pipe strainers are divided into direct flow and indirect flow type; the density of the filter net is 10 to 120 meshes; the temperature is 0 to 450 ℃, and they can be selected according to the user's needs.
