Cast Iron T Type Strainer Flanged 150# — Overview
Krishna Industries (KELOR) supplies the Cast Iron T Type Strainer Flanged 150# — also known as a basket strainer — a mechanical filtration device installed in piping systems to remove solid particles such as rust, scale, sand, welding slag, and pipe debris from process fluids. The T-shaped body has a vertical screen chamber (perpendicular to the pipeline flow) that houses a removable cylindrical screen basket. Process fluid flows straight through the strainer body and passes through the screen, which traps debris on its outer surface while allowing clean fluid to continue downstream.
The T type configuration provides several advantages over the smaller Y strainer design. The larger screen basket gives significantly more filtration area relative to the pipe size, meaning the strainer can handle higher debris loads before requiring screen cleaning. The top cover provides full access to the screen basket for easy removal, cleaning, and replacement without disturbing the pipeline connections. The straight-through flow path produces lower pressure drop compared to the angled Y body. KELOR supplies T type strainers in four body materials — CI, WCB, CF8, and CF8M — from verified vendor partners with Pan India dispatch from the Ahmedabad warehouse.
How a T Type Strainer Works
A T type strainer is named for its T-shaped body geometry. The pipeline fluid flows horizontally through the straight section of the T body and passes through the cylindrical screen basket installed in the vertical chamber. Solid particles larger than the screen perforations are trapped on the outer surface of the screen. Clean filtered fluid exits through the outlet and continues downstream to protect pumps, control valves, flow meters, heat exchangers, and other sensitive equipment. As debris accumulates on the screen surface, the pressure drop across the strainer increases. When the differential pressure reaches the alarm setpoint (typically 1.0 to 1.5 bar), the screen must be removed and cleaned.
1
Fluid Enters Inlet
Process fluid (water, steam, oil, gas, chemical) enters the horizontal leg of the T body at pipeline velocity. The flow is directed toward the vertical screen chamber.
2
Screen Filtration
Fluid passes through the perforated screen basket. Particles larger than the perforations are trapped on the outer surface. Clean fluid continues through the outlet to downstream equipment.
3
Debris Accumulation
Trapped debris accumulates on the screen surface over time. Pressure drop across the strainer increases. Monitor differential pressure to determine cleaning intervals.
4
Screen Removal & Cleaning
Shut down, isolate the strainer, unbolt the top cover, and lift out the screen basket. Clean by brushing, compressed air, or backwashing. Replace screen if damaged.
T Type vs Y Strainer
The two most common industrial strainer types are the T type (basket strainer) and the Y strainer. Both perform mechanical filtration to protect downstream equipment, but they differ in capacity, maintenance access, and installation space requirements. Selecting the correct type depends on the pipe size, debris load, cleaning frequency, and available installation space.
| Parameter | T Type (Basket) Strainer | Y Strainer |
|---|---|---|
| Screen Area | Large — cylindrical basket provides 4 to 10 times the screen area of a Y strainer for the same pipe size | Small — limited by the angled pocket diameter, typically 2 to 3 times the pipe cross-sectional area |
| Debris Capacity | High — large basket holds more debris between cleaning cycles — suited for high-debris service | Low to Moderate — smaller screen fills quickly under high debris loads — requires frequent cleaning |
| Screen Access | Full top cover removal — basket lifts straight out vertically for easy cleaning | End cap removal from angled pocket — less convenient, especially in tight spaces |
| Pressure Drop (Clean) | Lower — straight-through flow path produces less resistance | Higher — flow direction change at the Y junction creates additional resistance |
| Installation Space | Requires more vertical clearance above the pipeline for cover removal and basket extraction | More compact — fits in tighter installations where vertical clearance is limited |
| Best For | DN80+ pipe sizes, high debris load, continuous process, pump protection, frequent cleaning needed | DN15 to DN150, moderate debris load, steam/gas service, compact installations |
💡 Selection Rule
For pipe sizes DN80 and above or where debris load is high and cleaning frequency is expected to be more than once per month, specify T type strainer. For pipe sizes DN15 to DN80 with moderate debris load and where installation space is limited, specify Y strainer. For continuous-process plants where shutdown for strainer cleaning is unacceptable, consider duplex T type strainer (two baskets — one in service while the other is being cleaned).
Body Material Selection
CI — Cast Iron
WCB — Carbon Steel
CF8 — SS304
CF8M — SS316
| Body Material | Standard | Specify For | Not For |
|---|---|---|---|
| CI (Cast Iron) | GG25 / FC250 | Water, compressed air, HVAC chilled water, fire-fighting, general industrial service — most economical option | Corrosive chemical, chloride water, seawater, pharmaceutical — CI corrodes in these services |
| WCB (Carbon Steel) | ASTM A216 WCB | Steam, oil and gas, high-temperature water, general process piping — higher strength than CI | Corrosive chemical, seawater, food-grade — WCB corrodes without corrosion allowance |
| CF8 (SS304) | ASTM A351 CF8 | DM water, mild chemical, HVAC, food processing (non-chloride), general corrosion-resistant service | Seawater, chloride above 150 ppm, treated cooling water with chlorine biocide |
| CF8M (SS316) | ASTM A351 CF8M | Seawater, chemically treated cooling water, chloride service, chemical process, pharmaceutical — 2–3% Mo provides pitting resistance | Standard non-corrosive service where CI or WCB is adequate — unnecessary premium cost |
Screen & Mesh Selection
The screen mesh size determines the minimum particle size the strainer will capture. KELOR supplies T type strainers with SS304 or SS316 perforated screen baskets in standard mesh sizes. Correct mesh selection balances downstream equipment protection with acceptable pressure drop and cleaning frequency.
| Mesh Size | Approx. Opening | Best For |
|---|---|---|
| 10 Mesh | 2.0 mm | Coarse debris removal — gas and steam service — large particle protection only |
| 20 Mesh | 0.85 mm | Standard for steam and gas — removes pipe scale and welding slag — low blockage rate |
| 40 Mesh | 0.42 mm | ✓ Standard for liquid service — pump protection on water — most common for process piping |
| 80 Mesh | 0.18 mm | Fine filtration — spray nozzles, metering pumps, control valve protection |
| 100 Mesh | 0.15 mm | Very fine — pharmaceutical, food-grade, specialty chemical — frequent cleaning required |

Applications
Water Treatment Plants
Municipal water supply, RO plant feed, DM plant inlet, and effluent treatment use T type strainers for pump protection. The large basket capacity handles high solid loads from raw water sources.
Chemical Processing
Chemical and petrochemical plants use CF8 or CF8M body T type strainers for corrosion resistance. PTFE-lined baskets available for aggressive chemical service. Protects expensive control valves and heat exchangers.
HVAC & Building Services
HVAC chilled water, hot water, and cooling tower circuits use CI body T type strainers. Low pressure drop design minimises pump energy consumption while protecting heat exchangers and control valves.
Oil & Gas / Power Generation
Oil and gas pipelines, steam systems, and power plant auxiliary cooling water use WCB body T type strainers. High-temperature capability and robust construction for demanding industrial environments.
Installation Guidelines
A T type strainer must be installed correctly to ensure reliable filtration performance and safe maintenance access. The vertical screen chamber must point straight down in horizontal pipeline installations. Sufficient clearance above the strainer is required for removal of the screen basket during maintenance. The following guidelines apply to all T type strainer installations:
🔧 Installation Steps
- Install with the screen chamber pointing straight down in horizontal pipelines for gravity-assisted debris collection
- Provide minimum 300mm clearance above the top cover for screen basket extraction during maintenance
- Ensure flow direction arrow on the body matches the pipeline flow direction — arrow points from inlet to outlet
- Use full-face gaskets between flanges and tighten bolts in a criss-cross pattern to specified torque
- Install isolation valves on both upstream and downstream sides for safe screen removal without draining the entire pipeline
- On new pipelines, install with 20 mesh screen initially to capture construction debris, then upgrade to finer mesh after flushing
- Never install a T type strainer with the screen chamber pointing upward — debris falls away from the screen and filtration efficiency drops
⚠ Vertical Pipeline Installation
In a vertical upward-flow pipeline, the screen chamber must point sideways (3 o’clock or 9 o’clock) so that debris collects against the screen by gravity while flow passes upward. Never install a T type strainer with the screen chamber pointing straight down in a vertical pipeline, because removing the cover releases all collected debris downward into the lower piping where it can damage downstream equipment.

Frequently Asked Questions
What is the difference between a T type strainer and a Y strainer?
A T type strainer (also called basket strainer) has a large vertical screen chamber perpendicular to the flow path. The screen is a cylindrical basket element that provides a large filtration surface area relative to the pipe size. A Y strainer has a smaller angled screen pocket and less screen area. T type strainers are specified for higher debris load applications and larger pipe sizes where the Y strainer screen would fill too quickly. T type strainers also allow easier screen removal and cleaning because the top cover provides full access to the basket. Y strainers are more compact and are specified for moderate debris loads and smaller pipe sizes where space is limited.
What mesh size should I use for a T type strainer on water service?
For water service with centrifugal pump protection, specify 40 mesh (approximately 420 micron) perforated screen. 40 mesh removes rust flakes, scale, sand, and general pipe debris without excessive pressure drop. For coarse debris removal and steam service, 20 mesh is standard. For fine filtration protecting spray nozzles or metering pumps, specify 80 mesh. For initial commissioning of new pipelines, use 40 mesh first to capture construction debris, then upgrade to finer mesh after the pipeline has been flushed and the debris load has stabilised.
What body material should I select for a T type strainer?
For water, steam, compressed air, and general industrial service: CI (cast iron) or WCB (carbon steel) — the most economical options. For non-chloride corrosive service including DM water, mild chemical, and HVAC chilled water: CF8 (SS304). For chloride-containing service including seawater, treated cooling water, and chemical process: CF8M (SS316) — the 2 to 3% molybdenum in CF8M provides resistance to chloride pitting that CF8 does not have.
How often should the screen be cleaned in a T type strainer?
Screen cleaning frequency depends on the debris load in the pipeline and the mesh size specified. Monitor the differential pressure across the strainer during operation. When the pressure drop increases to approximately 1.0 to 1.5 bar above the clean strainer pressure drop, the screen must be cleaned. In clean water service with 40 mesh screen, cleaning may be required every 2 to 4 weeks. In dirty water or high-debris service, cleaning may be needed daily or weekly. Establish a cleaning schedule based on actual operating experience.
Can a T type strainer be installed in a vertical pipeline?
A T type strainer can be installed in a vertical pipeline with the screen chamber pointing sideways (3 o’clock or 9 o’clock position) in a vertical upward-flow pipeline. Never install with the screen chamber pointing straight down in a vertical line because removing the screen releases all collected debris into the lower piping. For horizontal pipelines, the screen chamber must point straight down for gravity-assisted debris collection. Always ensure adequate clearance above the strainer for vertical removal of the screen basket during maintenance.
What is the MOQ and delivery time for CI T type strainers?
MOQ is 10 Nos per size per body material. Standard CI body sizes DN50 to DN200 are dispatched within 3 to 5 working days from the Ahmedabad warehouse. WCB, CF8, and CF8M body strainers and sizes DN250 to DN600 may require 5 to 10 working days.
