CAST IRON Y TYPE STRAINER DRP®

  • DRP (DRP Metal Works / DRP Group) is a well-known Indian manufacturer of valves, pipe fittings, cast iron, cast steel, stainless steel etc. DRP Group+2DRP Group+2

  • Their quality policy is ISO-9001:2015.

Parameter Likely Values / DRP Range / What to Confirm
Body Material Cast Iron, probably IS 210 Grade FG 200 (a common cast iron grade in India) or equivalent.
Cover / Bonnet / Screen Retainer Cast Iron, bolted or screwed cover; screen likely stainless steel (SS-304) perforated sheet or mesh.
Screen Material SS 304 perforated plate / mesh; perforation size maybe ~3 mm or finer depending on model.
End Connections Could be flanged (common if larger sizes), or screwed / BSP / NPT for smaller sizes.
Size (Nominal Diameter) Likely range from about ½-inch to large sizes (e.g. DN 300 or more) in flanged types; smaller in screwed types.
Pressure Rating Probably around PN 10, PN 16, or pressure class equivalent (in kgf/cm²) = ~10-16 kg/cm²; for cast iron, above that is less common.
Temperature Range Ambient / water / steam service at moderate temperature; maybe up to ~200-220 °C maximum, depending on gasket / screen, etc.
Testing Hydrostatic test of body / shell; some differential pressure test; quality assurance under ISO-9001.
Finish / Coating Usually natural cast iron finish; possibly painted, or with some anti-corrosive treatment; drain plug provided.
Gasket / Seal Gasket material (if flanged or bonnet cover) likely according to IS standard (e.g. steam jointing sheet / compressed asbestos-free gasket / rubber depending on application).

Uses / Applications

These kinds of cast iron Y-type strainers are generally used to:

  • Protect downstream equipment such as pumps, valves, meters, steam traps, control valves, heat exchangers from particulate solids (scale, rust, weld spatter, debris).

  • For water lines, cooling water, non‐corrosive fluids, steam lines of moderate temperature, perhaps oil service if lubricated and non-aggressive.

  • Industrial / municipal / plumbing / HVAC systems.


Pros & Cons (for Cast Iron Y-Type, DRP / in general)

Here are likely advantages and drawbacks of a DRP cast iron Y-type strainer:

Pros:

  1. Cost effective — cast iron is relatively inexpensive compared to steel or exotic alloys.

  2. Good durability under moderate service conditions.

  3. Adequate strength for many standard water / steam / general industrial fluids (within its temperature / pressure limits).

  4. Easy maintenance — Y-type design allows removal of screen, cleaning, sometimes without full shut down depending on layout.

  5. Wide availability — parts, repair, screen replacement likely easier in domestic market.

Cons:

  1. Limited pressure & temperature — cast iron becomes brittle at higher temperatures; has lower tensile strength than steel; risk of cracking under thermal shock or under high pressure.

  2. Corrosion — cast iron can corrode; if fluid is aggressive (acidic, salty, etc.), or in moist ambient, corrosion could shorten life. Protection (painting, coatings) helps but adds cost.

  3. Weight — cast iron items are heavier; handling, installation more laborious.

  4. Brittleness — more sensitive to shock loading or sudden thermal changes.

  5. Maintenance access — bonnet / cover clearance needed; draining etc.


What to Check to Get the Exact DRP Spec

If you need the actual DRP Cast Iron Y-Type Strainer spec, check or ask for:

  • DRP catalog / data sheet for Y-type strainers (cast iron body).

  • The size range and end connection types they offer (flanged vs screwed).

  • Pressure rating (PN / kg/cm² / psi) for each size.

  • Material standard for body, screen, gasket.

  • Maximum working temperature.

  • Perforation or mesh size of screen.

  • Test pressures (hydrostatic / shell).

  • Drain plug (yes/no) and orientation (Y-angle).
