Y Type Strainer Supplier Guide: Selection & Specifications

Published 20 Sept 20266 min read

A Y-type strainer can be installed at the front of a water pump or pipeline to intercept impurities and protect downstream equipment. Buyers should select it according to the actual pipeline requirements, but the diameter, pressure rating, connection details, and temperature range must be confirmed before purchase. When comparing a y type strainer supplier, ask for written confirmation of every project-critical specification.

Check the body, cover, and screen materials

The available product information identifies the main construction materials as follows:

The specific process behind the cover's special formed design has not been stated. Buyers should not interpret it as a named manufacturing process without written technical confirmation.

The available information also does not confirm a specific ductile iron grade. Do not assume a material designation such as QT450, GGG40, or GGG50 unless it is confirmed for this product.

ComponentConfirmed information
BodyDuctile iron casting with epoxy resin coating
CoverDuctile iron
Screen304 stainless steel
Cover designThe top has a special formed design intended to reduce damage caused by sand and stone impact or rotary friction

Do not finalize diameter or pressure from an unconfirmed listing

The DN80 / PN16 marking on one strainer body. A marking on a single item does not define the diameter or pressure range for the whole series.

Diameter and pressure are key purchasing parameters, but the available information is not consistent enough to establish a final range.

The DN100 / PN16 marking on the product photograph must not be treated as the specification for the complete product range. Similarly, the displayed diameter ranges must not be used as final project data until the supplier confirms the required size and pressure in writing.

For a project purchase, provide the required pipeline diameter and design pressure to the Y-Type Strainers product team, then request a product-specific confirmation.

Treat connection and standard details as open items

  • Connection type
  • Flange drilling standard
  • Flange pressure class
  • Thread specification, such as BSP or NPT
  • Applicable product standard
  • Pressure test standard

Confirm operating conditions before ordering

The available product information does not provide a temperature range or a confirmed list of suitable media. It does not establish whether this product is suitable for drinking water, steam, or oil service.

Before issuing a purchase order, confirm:

1. The operating medium.

2. The operating temperature.

3. The required diameter.

4. The required pressure rating.

5. The connection type and applicable dimensions.

6. The screen specification required for the application.

7. Any project-specific documentation requirements.

The screen material is identified as 304 stainless steel, but the screen mesh count is not confirmed. Do not specify a mesh value based on general information from another source.

If the pipeline also requires non-return protection, buyers can compare the available ball check valves or swing check valves as separate products. Their selection should be based on the project's own operating requirements.

Use a written confirmation checklist for supplier comparison

A reliable comparison between suppliers should focus on confirmed technical information rather than an unverified model name or online range. Ask each y type strainer supplier to confirm the following items for the exact quotation:

No verifiable certification is provided in the available product information. Buyers should request current supporting documents if certification is required by the project.

ScreenConfirm 304 stainless steel and the required mesh specification
ConnectionConfirm flanged or threaded connection, as applicable
DimensionsRequest approved dimensions for the selected size
Temperature and mediumConfirm suitability for the stated service conditions
Testing documentsConfirm what product documents are available
CertificationsConfirm whether any verifiable product certification is available
