TIANYU Flanged Carbon Steel Fabricated T-Type Strainer

I. Product Overview

TIANYU flanged carbon steel fabricated T-type strainer is a key impurity filtration device for industrial fluid pipelines. It uses a T-type structure and basket-shaped filter screen to efficiently intercept solid particles in fluids, preventing downstream equipment such as pumps, valves, and heat exchangers from wear or blockage. With a focus on easy maintenance and stable performance, it is widely used in systems conveying water, oil, and steam, providing reliable protection for pipeline operations.

II. Key Attribute Parameters

Size and Pressure

Nominal Diameter (DN): Covers DN25-DN1000, adapting to both small-caliber precision pipelines and large industrial main pipelines.
Pressure Class: Available in 10K and 20K. The maximum inlet pressure for 10K is 15kgf/cm², and for 20K is 30kgf/cm², meeting the needs of medium and high-pressure systems.

Medium and Temperature

Applicable Fluid: Water, oil, steam, and other common industrial fluids.
Applicable Temperature: 220℃-350℃, suitable for medium to high-temperature working conditions such as steam pipelines.

Connection and Sealing

Connection Mode: 10K RF flanged (for 10K class) and 20K RF flanged (for 20K class), ensuring tight connection with pipeline flanges and reducing leakage risks.
Sealing Components: Buna-N O-ring seals on the cover, replacing traditional gaskets to avoid frequent replacement during maintenance.

Material and Testing

Body & Cover: Made of cast iron, WCB (carbon steel), or stainless steel (S.S.), with carbon steel as the mainstream choice for cost-effectiveness and adaptability to most neutral fluids.
Filter Screen: 304 stainless steel porous sieve, featuring corrosion resistance and high strength, not easy to deform under fluid impact.
Hydrostatic Test: 15kgf/cm² for 10K type and 30kgf/cm² for 20K type, verifying the pressure resistance and sealing performance of the strainer.

Product Overview

III. Feature Description

Convenient Maintenance Design

The inner screen is a basket-type structure with a lifting handle, allowing all trapped particles to be easily removed during cleaning. The top cover adopts a swivel clamp design, enabling screen removal without tools—greatly reducing maintenance time, especially suitable for scenarios requiring frequent cleaning.

Efficient Filtration Performance

With a full filtration area (larger than the pipeline cross-section), it ensures sufficient contact between fluid and the screen, improving impurity interception efficiency. The optimized flow channel design minimizes pressure loss, avoiding excessive energy consumption of the pipeline system.

Reliable Sealing Performance

The cover uses a Buna-N O-ring seal instead of traditional asbestos gaskets, which not only enhances sealing reliability but also eliminates the need for gasket replacement during each maintenance, reducing operational costs.

Wide Working Condition Adaptability

Available in 10K and 20K pressure classes, with a temperature range of 220℃-350℃, it can adapt to different fluid pressures and temperatures, meeting the needs of both low-pressure water pipelines and high-pressure steam systems.

IV. Manufacturing Process

TIANYU flanged T-type strainer adopts a fabricated manufacturing process, which involves prefabricating key components (such as the body, cover, and screen frame) through cutting, welding, and machining, then assembling them into a complete product.

Component Fabrication: Carbon steel plates/pipes are cut into standard sizes, and the body and cover are formed by precision welding to ensure structural strength. The 304 stainless steel screen is woven or punched into a basket shape, with a lifting handle welded for easy operation.
Precision Machining: The flange sealing surface and cover mating surface are machined to ensure flatness and dimensional accuracy, laying the foundation for reliable sealing.
Quality Inspection: After assembly, each strainer undergoes a hydrostatic test (15kgf/cm² for 10K, 30kgf/cm² for 20K) to check for leaks. The screen is tested for strength to ensure it does not deform under rated pressure.

V. Product Advantages

Reduced Maintenance Costs

The quick-open cover and basket-type screen with a handle allow maintenance personnel to clean impurities in minutes without tools, reducing equipment downtime by over 50% compared to traditional strainers.

High Filtration Efficiency

The full filtration area design ensures that over 95% of particles larger than the screen aperture are intercepted, effectively protecting downstream precision equipment and extending their service life by 30%-50%.

Energy-Saving Performance

Low pressure loss (≤5% of the system pressure) reduces the load on pumps and other power equipment, saving 3%-8% of energy consumption for long-term operation of the pipeline system.

Long Service Life

The body and cover made of WCB carbon steel have strong corrosion resistance and wear resistance; the 304 stainless steel screen is not easy to rust or break, ensuring a service life of 5-8 years under normal working conditions.
