Tee vs Y vs Basket Strainer Selection Guide
| Item | Tee Type Strainer | Y Type Strainer | Basket Type Strainer |
|---|---|---|---|
| Flow Direction | Straight through (T shape) | Angled (Y shape) | Straight through (basket chamber) |
| Pressure Drop | Higher than Y type | Low | Medium |
| Filtration Area | Medium | Small | Large |
| Best For | Large diameter, high-flow, permanent protection | Steam, gas, oil, general pipeline | High dirt load, frequent cleaning service |
| Size Range | Up to 48 inch (DN1200) | Up to 36 inch (DN900) | Up to 36 inch (DN900) |
Reference: ASME B16.34, API 598. Tee strainer provides straight-through flow and is preferred for large diameter and high-flow pipeline; Y strainer offers the lowest pressure drop for general service; Basket strainer provides the largest filtration area for high dirt load service.
Tee Strainer Applications
• Large diameter pipeline: main water lines, oil and gas transmission with sizes up to 48 inch requiring straight-through flow and low pressure drop.
• Water treatment and distribution: municipal water networks, pump suction and discharge protection in large diameter fabricated tee strainer.
• Oil and gas process piping: refinery process lines, pump protection and general hydrocarbon service with ANSI Class 150 to 600.
• Power plant and boiler service: feedwater, condensate and cooling water protection lines with large filtration area tee strainer.
• Chemical and petrochemical: corrosive media filtration with SS304 / SS316 / SS304L / SS316L fabricated body and 304SS / 316SS screen.

FAQ - Tee Strainer (T Type Strainer)
Q1: What is a Tee Strainer (T Type Strainer)?
A: A Tee Strainer, also called T Type Strainer, is a fabricated pipeline strainer with a T-shaped body comprising an equal tee fitting with weld neck flange and blind flange connected to the branch. It is designed to remove foreign particles and impurities from liquid, gases and pipe systems, protecting downstream pumps, valves, meters and other equipment. The straight-through tee design provides excellent flow characteristics and is available in sizes up to 48 inch (DN1200). It is an economical type of strainer used in commissioning or permanent protection of large diameter pipelines.
Q2: What is the difference between Tee Strainer and Y Strainer?
A: Tee strainer has a T-shaped body with straight-through flow, while Y strainer has a Y-shaped body with angled flow. Tee strainer is typically lighter and more economical than Y strainer for large diameter service, and provides excellent flow characteristics for high-flow pipelines. Y strainer offers lower pressure drop and is more compact, making it suitable for general steam, gas and oil pipeline service. For large diameter (above 24 inch) and high-flow applications, tee strainer is often the preferred choice. Tee strainer is also easier to fabricate in large sizes, with sizes available up to 48 inch.
Q3: What end connections are available for Tee Strainer?
A: Tee strainers are available with two end connection types: Flange Ends and BW (Butt Weld) Ends. Flanged ends include RF (Raised Face) and FF (Flat Face) to ASME B16.5 (size under 24 inch) or ASME B16.47 (size above 24 inch). BW ends are to ASME B16.25 for permanent welded connection. The tee strainer body is fabricated from an equal tee fitting, with the branch closed by a blind flange cover. Drain plug is available on request for draining the strainer before maintenance. Face-to-face dimension follows ASME B16.10.
Q4: What body materials are available for Tee Strainer?
A: Body materials include carbon steel A234-WPB, stainless steel 304SS / 304LSS / 316SS / 316LSS, with flange and cover in A105 for carbon steel or A182-F304 / F304L / F316 / F316L for stainless steel. The tee fitting is the main body component, fabricated from A234-WPB wrought carbon steel fitting material or stainless steel pipe. Gasket is graphite + 304SS / 316SS / 304LSS / 316LSS; screen is 304SS or 316SS. For high-chloride or seawater service, duplex and super duplex materials are available on request. Tailor-made materials are also available.
Q5: What is the size range and pressure rating available?
A: Tee strainers are available from 2 inch to 48 inch (DN50 to DN1200). Pressure ratings include ANSI Class 150LB (19.6 bar / 285 psi), Class 300LB (51 bar / 740 psi) and Class 600LB (102 bar / 1,480 psi). The tee strainer is particularly suitable for large diameter service, with sizes above 24 inch using ASME B16.47 large diameter flange. For sizes above 36 inch, fabricated tee strainer is the standard choice. Tailor-made sizes and pressure ratings are available on request.
Q6: How do I maintain a Tee Strainer?
A: Maintenance is simple: isolate the strainer, depressurize, open the drain plug to drain the strainer, remove the blind flange cover bolts, take out the screen, clean or replace it, install a new gasket, and reassemble. The tee strainer body is fabricated from an equal tee fitting, with the branch closed by a blind flange. For large diameter tee strainers (above 24 inch), a davit arm or lifting lug is recommended for heavy cover handling. Screen replacement is recommended when the pressure drop exceeds the initial clean-screen value by 0.5-1.0 bar. For continuous operation without pipeline shutdown, a duplex tee strainer configuration is recommended.
