Pipeline strainer product attributes

Strainer records usually combine two products: the body and the screen inside it. The body is described by type (Y, basket, duplex), size, end connection, pressure class and material. The screen is described by opening size, perforation or mesh, material and open area. Supplier files often list only the default screen, so the record says nothing about the alternatives that fit the same body.

Screen opening is the most error-prone value. Perforated plate is sized by hole diameter, woven mesh by wires per inch, and some suppliers add a micron equivalent. A bare "20" in a feed could be a mesh count or part of a code. End connections are written in many ways, and threaded, socket weld and flanged versions of the same size carry different pressure-temperature limits.

A buyer needs the size and connection that fit the line, a pressure-temperature rating that covers the service, a screen opening that protects the downstream equipment, and wetted materials suited to the fluid. For maintenance, the replacement screen part number and the blowdown connection size are as useful as the body data.

The strainers attribute template

18 candidate fields in 5 groups, ordered the way a record gets built: identify the item, capture its specifications, then record fit and the evidence behind any claim. 9 are marked Core: without them the item cannot be identified or filtered. Example values show the expected format only; they do not describe a real SKU.

Identity

Which exact item, variant and pack this record describes.

Check before use: Preserve leading zeros and punctuation, validate against the manufacturer record, and check the GTIN check digit and packaging level before linking.

Attribute	Type	Priority	Example format
Manufacturer Part Number (MPN) manufacturer_part_number_mpn	Identifier	Core	YS-2F150-SS-062
GTIN / UPC gtin_upc	Identifier	Core	0614141001088

Technical specifications

Measured or rated values that must travel with their unit and test conditions.

Check before use: Store the number and unit separately. Convert only when the source unit and test conditions are known.

Attribute	Type	Priority	Example format
Nominal Size (NPS / DN) nominal_size_nps_dn	Controlled list · in / DN	Core	2 in (DN50)
Pressure Class pressure_class	Controlled list	Core	Class 150
Pressure–Temperature Rating pressure_temperature_rating	Text · psig	Buyer decision	275 psig at 100 °F (Class 150, CF8M)

Selection attributes

The type, material and option choices buyers filter and compare on.

Check before use: Map supplier wording to a governed vocabulary only after checking the source text and which variant it applies to.

Attribute	Type	Priority	Example format
Strainer Type strainer_type	Controlled list	Core	Y-strainer (wye)
Body Material body_material	Controlled list	Core	ASTM A351 CF8M (cast 316)
Screen / Element Material screen_element_material	Controlled list	Core	316 stainless steel
Screen Opening (Perforation or Mesh) screen_opening_perforation_or_mesh	Controlled list · in / mesh	Core	1/16 in (1.6 mm) perforated
Screen Open Area Ratio screen_open_area_ratio	Number	Buyer decision	3.0 (3:1)
Micron Equivalent micron_equivalent	Number · µm	Buyer decision	1,588 µm (1/16 in perforation)
Seal & Gasket Material seal_gasket_material	Controlled list	Buyer decision	PTFE cover gasket

Fit & compatibility

What the item mounts to, mates with, replaces or works alongside.

Check before use: Keep model and series qualifiers. A similar-looking part is not a verified fit until a source says so.

Attribute	Type	Priority	Example format
End Connection end_connection	Controlled list	Core	Flanged, ASME B16.5 Class 150 RF
Blowdown / Drain Connection blowdown_drain_connection	Controlled list · in	Buyer decision	1/2 in NPT, plugged
Replacement Screen MPN replacement_screen_mpn	Identifier	Buyer decision	SCR-2-062-316

Evidence & compliance

Listings, standards, classifications and origin claims that need a document behind them.

Check before use: Link the manufacturer document or label with its edition or date. Never copy a certification from a neighboring SKU.

Attribute	Type	Priority	Example format
Country of Origin country_of_origin	Controlled list	Channel / evidence	United States
Design & Shell Test Standard design_shell_test_standard	Controlled list	Channel / evidence	ASME B16.34 Class 150 body; hydrostatic shell test
Potable Water Certification potable_water_certification	Controlled list	Channel / evidence	NSF/ANSI/CAN 61 & 372 certified

Normalize supplier values

The same value arrives in many spellings. Map each raw string to one governed value, and keep the raw text beside it so a reviewer can see what the supplier actually wrote.

Often missing from supplier files

These fields are commonly absent from price lists and basic feeds, even though the information usually exists in a datasheet, label or installation manual. Treat an empty value as a request for evidence, not as permission to fill it from a similar model.

• Screen open area ratio
• Micron equivalent
• Pressure-temperature rating
• Blowdown / drain connection
• Replacement screen MPN

Questions the record must answer

Buyers and counter-sales reps choosing strainers ask questions like these. Each one needs a specific field, sourced for the exact variant.

• Which replacement screen fits this strainer, and what opening sizes are available?
• Is this strainer rated for steam at our operating pressure?
• Will it catch particles down to the size our pump or meter requires?
• Does it have a tapped blowdown connection, and what size?

From supplier file to record

1. Resolve identity first. Link the supplier SKU, manufacturer part number and packaging identifiers without merging distinct variants or pack sizes.
2. Extract with the source attached. Pull values from rows, tables and datasheets, keeping the raw text, unit and page or row reference.
3. Map to your classification. Assign the ETIM, ECLASS, UNSPSC or internal class your company licenses, and keep the supplier's original terms.
4. Review, sync and watch. Hold conflicts and safety-related values for a category expert, write approved values to ERP or PIM, and recheck when the supplier sends a new file.
