SS Y Type Strainer Supplier in India
Krishna Industries (KELOR), based in Ahmedabad, Gujarat, supplies SS Y Type Strainers — SS304 (CF8) / SS304L / SS316 (CF8M) / SS316L (CF3M) body — SS316 or SS316L perforated or wire mesh screen — flanged ASME B16.5 Class 150 / Class 300 / screwed BSP NPT / socket weld / butt weld — DN15 (½”) to DN300 (12″) — PN10 to Class 300 — GST invoice — MOQ 10 Nos — Pan India dispatch from Ahmedabad.
An SS Y Type Strainer is installed upstream of pumps, control valves, pressure reducing valves, flow meters, steam traps, and sensitive process equipment to remove solid particles — rust, scale, sand, welding slag — before they cause damage. Furthermore, stainless steel body construction is mandatory for pharmaceutical GMP utility piping, food and beverage processing, corrosive chemical service, seawater cooling, and DM water systems where carbon steel corrodes internally and brass pressure or temperature ratings are insufficient.
SS Grade Selection — SS304 vs SS316 vs SS316L
The SS grade is the most important specification decision for an SS Y strainer. Moreover, it is the specification that separates a pharma GMP-compliant installation from a non-compliant one. Selecting the wrong grade results in corrosion failure in aggressive media or GMP audit rejection in pharmaceutical applications.

Weld Sensitisation Risk
Specify For
Not For
SS304 (CF8)
0.08% C
None
Present in welded HAZ in aggressive environments
✅ DM water, mild chemical, food non-chloride, pharma non-GMP utility — economical SS strainer for non-chloride service
Chloride-containing media (pitting) — seawater — aggressive acid/alkali — GMP pharma where 316L is specified
Welded non-chloride SS piping where sensitisation prevention needed but Mo of SS316L not required — cryogenic welded SS piping
Chloride service — no Mo — same pitting risk as SS304
SS316 (CF8M)
0.08% C
2–3% Mo
Present in welded HAZ in aggressive chemical service
✅ Chloride service, seawater cooling, coastal industrial, aggressive chemical — where SS304 pitting resistance insufficient
GMP pharma welded piping where sensitisation at weld HAZ is a concern — specify SS316L instead
SS316L (CF3M)
0.03% C max
2–3% Mo
✅ Eliminated — low carbon + molybdenum — both sensitisation-free and chloride-resistant
✅ Pharma GMP utility (PW, WFI, clean steam — USFDA/WHO GMP specifications require 316L) — welded SS chemical piping in corrosive service — food GMP where 316L documentation required — most conservative and widely specified Indian SS strainer grade for pharma and chemical
Very high temperature above 450°C — SS316L loses strength faster than SS316 at extreme temperature

Corrosion in Water
✅ Good — DR brass resists standard water — not for chloride or aggressive water
Corrodes internally — rust contaminates downstream equipment — not suitable for water without internal coating
✅ Excellent — SS316 resists chloride, seawater, aggressive chemical — SS304 for non-chloride water and mild chemical
Hygiene / Food/Pharma
Not suitable — brass contains lead and zinc — not food-grade approved for product-contact service
Not suitable — iron contamination risk — not food or pharma grade
✅ Food-safe and pharma-compliant — SS316L standard for GMP piping — no lead, zinc, or iron contamination — cleanable surface
Temperature
Up to 150°C (steam) — pressure limited above 100°C
✅ Up to 425°C with CS — high temp steam and process
✅ -196°C to +425°C (cryogenic to high temp) — SS maintains toughness at cryogenic temp unlike CS
Pressure Rating
PN16 standard — limited
✅ Class 150 to 2500 — high pressure capable
✅ Class 150 to 300 standard — adequate for most pharma, food, and chemical service
End Connection
BSP/NPT threaded DN8–DN80 — compact utility
Flanged / screwed — DN15–DN200 — process plant
✅ Flanged / screwed BSP/NPT / SW / BW — DN15–DN300 — full range
Cost
✅ Lowest — economical for plumbing and HVAC
Medium — economical for process plant CS piping
Higher — justified for corrosive service, hygiene, cryogenic
Specify When
Plumbing, HVAC, water supply, light industrial — BSP screwed — non-corrosive non-GMP service
Steam, oil, gas, process plant — flanged — CS piping class — where brass insufficient and SS not required
✅ Pharma GMP, food, chemical, coastal, seawater, DM water, cryogenic — any service where brass corrodes, CS contaminates, or GMP documentation requires SS

Applications in Indian Industries
Pharmaceutical GMP Utility Piping
SS316L CF3M flanged Class 150 DN25–DN80. Installed upstream of control valves, pressure reducing valves, and steam traps on purified water (PW), water for injection (WFI), and clean steam utility lines. SS316L mandatory for GMP documentation compliance — USFDA, WHO GMP, and EU GMP utility piping specifications cite 316L. Furthermore, SS316L screen provides full material traceability for GMP audit — no dissimilar metal grade in the wetted path. Pharma API plant clusters: Ahmedabad, Hyderabad, Baddi, Ankleshwar.
Chemical Plants — Ankleshwar, Vapi, Dahej
SS316 CF8M flanged Class 150/300 DN25–DN200. Upstream of control valves and flow meters on corrosive chemical process lines. SS316 for chloride-containing chemical, acid, and alkali service. Moreover, SS316L for welded SS chemical piping where sensitisation at weld HAZ in aggressive media is a concern. Screen protects control valve seat from particulate damage — leading cause of control valve seat leakage in Indian chemical plants.
Food and Beverage Processing
SS316 or SS316L flanged Class 150 DN25–DN150. Upstream of process control valves, CIP flow meters, and spray nozzles on food process and utility lines. SS316L for food GMP certification (FSSC 22000, BRC) where material documentation requires 316L throughout utility piping. In addition, smooth SS surface meets hygienic cleanability requirements for food contact environment piping.
DM Water and Utility Water Systems
SS304 flanged Class 150 DN25–DN100. Upstream of ion exchange resin beds, RO membrane feed, and boiler feed chemical dosing lines. DM water is corrosive to CS — SS304 adequate for DM water service without chloride. Consequently, SS304 is the standard specification for DM water system Y strainers in Indian power plants, chemical plants, and pharmaceutical utilities.
Seawater Cooling and Coastal Industrial
SS316 flanged Class 150 DN50–DN300. Upstream of seawater-cooled heat exchanger inlets, coastal pump suction strainers, marine process piping. SS316 molybdenum content provides chloride pitting resistance in seawater — SS304 pits rapidly in seawater and is not suitable. Therefore, specify SS316 for all coastal and seawater service Y strainers.
Cryogenic Service — Liquid Nitrogen and LNG
SS304 or SS316L flanged Class 150/300 DN25–DN100. Upstream of cryogenic control valves and flow meters on liquid nitrogen supply lines and LNG vaporiser piping. Austenitic SS maintains toughness and ductility at -196°C — CS becomes brittle at cryogenic temperatures. Furthermore, SS316L is specified for welded cryogenic SS piping to prevent sensitisation at weld joints.
Brass Y Strainer — brass body BSP threaded — DN8–DN80 — for plumbing, HVAC, water supply, and light industrial service where SS is over-specified
Duplex Strainer — SS316 inline duplex strainer — dual chamber — continuous operation without shutdown for cleaning — for critical service where Y strainer shutdown is not acceptable
MS Fabricated Basket Strainer — large bore MS body — simplex and duplex — DN80–DN600 — pump suction protection and cooling water where Y strainer is too small
SS316L Ball Valve — install downstream of SS316L Y strainer on pharma GMP and chemical plant utility lines — ball valve for isolation, Y strainer for protection
Frequently Asked Questions
1. When should I specify SS316L instead of SS316 for a Y strainer?
Specify SS316L when: the Y strainer is installed in a welded SS piping system where adjacent welds are made after strainer installation — low carbon 316L prevents sensitisation at the weld heat affected zone. Also specify SS316L when the project specification, piping class, or GMP requirement explicitly states 316L, CF3M, or ASTM A270 316L — any project for a USFDA, WHO GMP, or EU GMP approved pharma facility will typically require SS316L documentation throughout the utility piping system. For non-welded flanged or screwed connections in non-GMP service where the specification accepts SS316, standard CF8M SS316 is acceptable and slightly lower cost.
2. What MTC documentation is provided for pharma GMP service?
MTC (Material Test Certificate) for ASTM A351 CF3M (SS316L) body — confirms chemical composition (carbon ≤0.03%, molybdenum 2–3%, chromium 16–18%) and mechanical properties with heat number traceability. The MTC confirms the body material is genuine CF3M SS316L — this is the document GMP auditors request to verify material grade compliance. Specify “MTC required — GMP service” at order stage. In addition, SS316L screen MTC is available on request for full wetted path material traceability.
3. What screen perforation or mesh size should I specify for chemical dosing line protection?
For chemical dosing lines upstream of solenoid valves, metering pumps, and spray nozzles, specify 40 mesh (400 micron) wire mesh — fine enough to protect precision equipment from particles that cause plunger wear and nozzle blockage, while coarse enough to avoid rapid clogging in chemically treated water. For dosing lines handling crystallising chemicals, specify coarser 20 mesh (841 micron) — crystalline particles clog fine mesh rapidly. Furthermore, for pharma pure water and WFI service, specify 40 mesh SS316L wire mesh — 20 mesh is too coarse for protecting precision pharmaceutical instruments.
4. Can SS Y strainers be used for cryogenic service?
Yes — austenitic stainless steel (SS304 and SS316L) maintains toughness and ductility at temperatures down to -196°C (liquid nitrogen temperature). Carbon steel becomes brittle at cryogenic temperatures — CS Y strainers are not suitable for cryogenic service. Specify SS304 or SS316L flanged Class 150/300 for cryogenic Y strainer service. For welded cryogenic SS piping, specify SS316L to prevent sensitisation at weld joints adjacent to the strainer connections.
5. What is the MOQ?
MOQ is 10 Nos. Pharma and chemical plant project orders — typically 20 to 500+ Nos across sizes and grades — with ASTM A351 MTC, dimensional inspection report, and GST invoice. For GMP pharma orders, specify SS316L CF3M and request MTC confirmation at order stage.
