Types of Strainer
The strainer produced by our company mainly include the following types:
Y Type Strainer
Y-type Strainer is a device used to filter impurities and particulate matter in a pipeline system. It is named because of its "Y" shape. It is widely used in industries such as petroleum, chemical, water treatment, and electricity.
T Type Strainer
T-type filter is a device used to filter impurities and particulate matter in the pipeline system. It is named because of its "T" shape. It is mainly used to intercept solid particles in the medium, protect downstream equipment (such as pumps, valves, instruments, etc.) from damage, and ensure the normal operation of the system.


Simple structure, easy to install and maintain
The Y-type Strainer has a compact design, easy installation, and the end cover is removable, which is convenient for cleaning and replacing the filter.
Good filtering effect
Filters of different precisions can be selected according to needs to effectively intercept solid particles and protect downstream equipment.
Wide range of applications
Suitable for a variety of media such as liquids and gases, and can withstand high pressure and temperature.
Small pressure loss
The flow channel design of the Y-type Strainer is reasonable, and the pressure drop when the medium passes is small, which does not affect the system operation efficiency.
Strong durability
Made of corrosion-resistant and high-temperature resistant materials, it is suitable for harsh working conditions.
Handle large flow
The design of the T-type filter enables it to handle larger flow and is suitable for high-flow systems.
Good filtering effect
Filter screens of different precisions can be selected according to needs to effectively intercept solid particles and protect downstream equipment.
Strong structure
T-type filters usually adopt thicker wall thickness and stronger structural design, which is suitable for working conditions with high pressure and high impurity content.
Easy maintenance
The end cover is removable for easy cleaning and replacement of the filter screen.
Wide range of applications
Suitable for a variety of media such as liquids and gases, and can withstand high pressure and temperature.

Application of Y Type Strainer
Oil & Gas: Protects pumps, valves, and meters from pipeline debris.
Chemical Processing: Used to filter solid particles in corrosive media to extend the service life of equipment.
HVAC Systems: Removes particulates from chilled or hot water circuits.
Municipal Water Supply: Screens sediment in pipelines.
Irrigation Systems: Prevents nozzle blockages in agricultural setups.
Plumbing Systems: Installed upstream of water heaters or softeners to trap scale and rust.
Power industry: Used in boiler water supply system to prevent impurities from entering the boiler and causing damage.
Food and pharmaceutical industry: Used to filter impurities in liquids to ensure product purity.
Application of T Type Strainer
Industrial processes
T-Strainers are used in industrial processes to protect pumps, meters, valves, and other equipment from damage caused by debris and other particles. Industrial strainers are installed just before these components to strain the solid particles.
01
Chemical processing
T-strainers are used in chemical processing plants to protect pumps and other equipment from damage caused by particulates in the fluid. They also remove any particulates that may be formed during the chemical process.
02
Water and wastewater systems
T-strainers are used in water and wastewater systems to filter out debris, such as leaves, twigs, and other large particles before the liquid enters the processing plant.
03
Oil and gas systems
T-strainers are installed in oil and gas systems to protect equipment from damage caused by contaminants during the process and ensure that the final product is debris-free.
04
Fire protection systems
T-strainers are used in fire protection systems to protect pipelines, pumps, and nozzles from damage caused by debris and other particles and to prevent blockage when they are required to work.
05
Components of Y Type Strainer
Y-Shaped Body
The Y-shaped body is the defining feature of this type of strainer. It serves as the primary chamber through which fluid flows. Its design allows for the efficient separation of particles from the fluid.
Perforated or Mesh Screen
Located within the Y-shaped body, the perforated or mesh screen is the heart of the Y Type Strainer. It captures solid particles and impurities, preventing them from entering downstream equipment.
Strainer Cap
The strainer cap covers the Y-shaped body and screen, keeping contaminants trapped inside. It is removable to facilitate maintenance and cleaning.
Inlet and Outlet
The strainer has clearly marked inlet and outlet ports. The inlet is where the unfiltered fluid enters, while the outlet delivers the filtered fluid to downstream processes.
Drain Valve
At the base of the Y Type Strainer, a drain valve is typically provided. This valve allows for the controlled release of accumulated debris and particles during maintenance.
Seals and Gaskets
Seals and gaskets ensure a tight and leak-free seal between the strainer’s components, preventing fluid from bypassing the strainer screen.
Mounting Flanges or Connections
The strainer is equipped with mounting flanges or connections that facilitate its installation into the pipeline or process system.
Components of T Type Strainer
Body
The body of the T Type Strainer serves as the primary structure that houses the filtration element and provides the necessary framework for other components. It is typically made of durable materials such as cast iron, carbon steel, stainless steel, or exotic alloys, depending on the specific application and the nature of the fluids being filtered.
Filtration Element
At the heart of the T Type Strainer is the filtration element, which can take the form of a perforated sheet or a mesh screen. This element is strategically positioned within the body to capture particles and impurities present in the fluid.
Cap, Gasket, and Bolts
The cap of the T Type Strainer serves as the top cover, tightly securing the filtration element within the body. It is fastened in place by gaskets and bolts. The gasket, usually made of rubber or other resilient materials, forms a tight seal between the body and the cap.
Drain Plug
A drain plug is a small yet crucial component located at the bottom of the T Type Strainer. It serves as an access point for removing accumulated impurities and debris from the strainer. Periodically, when the strainer traps a substantial amount of contaminants, the drain plug is opened. This allows for easy disposal of the collected impurities, ensuring the strainer continues to function optimally.
Connection Ports
T Type Strainers are equipped with connection ports that facilitate the integration of the strainer into the pipeline system. These ports are strategically positioned on the body and are designed to match standard pipe sizes and configurations.
Basket Support
In some T Type Strainers, especially those designed for heavy-duty applications in the oil and gas industry, a basket support is included. This component provides additional reinforcement to the filtration element, preventing it from collapsing under high differential pressures.
