Y Strainer

A Y Strainer works by forcing the process fluid through a mesh/perforated straining element placed inside a “Y” shaped body. Solid particles get trapped in the filter element while clean fluid continues downstream. The trapped debris can be removed during maintenance, making it a simple yet highly effective pipeline protection component.

Both are used for filtration, but they serve slightly different purposes:

• Y Strainer: compact, economical, suitable for continuous operation, widely used for steam and gas lines, ideal for moderate dirt loads

• Basket Strainer: larger filtration capacity, lower pressure drop, suitable for higher debris load and larger flow systems

For compact piping and general equipment protection, Y Strainer is the preferred choice.

Y Strainers are typically installed:

• upstream of pumps (to prevent impeller damage)

• before control valves (to avoid clogging and seat damage)

• before steam traps (to prevent trap failure due to dirt)

• before flow meters and regulators

in utility and process pipelines where clean flow is essential

Mesh size selection depends on:

• process fluid type (steam, gas, water, chemical)

• expected particle size

• equipment sensitivity downstream

• allowable pressure drop

Petronash provides filter elements in all mesh sizes as per application requirement, ensuring optimum filtration without excessive pressure loss.

Petronash Y Strainers are engineered with a large filtration area, which ensures:

• better dirt holding capacity
• improved filtration efficiency
• minimal pressure drop compared to smaller filter area designs

This is crucial for maintaining stable flow in control valve and steam applications.

Petronash Y Strainers are offered in a wide range of pressure classes:
150#, 300#, 600#, 800#, 900#, 1500# & 2500#

This makes them suitable for low pressure utilities as well as high-pressure oil & gas process lines.

Petronash Y Strainers are available from:
3/8” to 4”

This range supports small instrument connections up to large process lines.

Petronash offers multiple end connection options for easy integration:

• Socket Weld (SW) as per ANSI B16.11
• Buttweld (BW)
• Threaded (NPT) as per ANSI B1.20.1
• Flanged (RF & RTJ) as per ANSI B16.5

This flexibility helps fit into EPC specifications and existing piping layouts.

RF (Raised Face) flange:

• common in general process piping
• cost-effective and widely used

RTJ (Ring Type Joint) flange:

• used in high-pressure, high-integrity service
• preferred in oil & gas and critical applications

Petronash provides both RF and RTJ flanged Y Strainers as per customer and project requirements.

Petronash Y Strainers are available in:

• F182 SS316 / 316L
• CF3M / CF8M
• A105
• WCB
• and other materials on request

This ensures compatibility for corrosion resistance, steam service, and high-pressure oil & gas requirements.

Yes. Petronash Y Strainers are designed as per ASME B16.34, with high corrosion allowance in wall thickness, which supports:

• longer product life
• enhanced safety margin
• reliable operation under harsh conditions

This makes the product ideal for refineries, offshore platforms, chemical plants, and utility lines.

Petronash Y Strainers are designed for durability, safety, and performance, with:

• ASME-compliant design
• multiple pressure classes up to 2500#
• multiple end connections (SW/BW/NPT/Flanged)
• wide material availability including SS316/316L and WCB

They are ideal for EPC projects and critical process piping systems.

Yes. Petronash provides customized solutions such as:

• custom mesh selection
• special metallurgy (Duplex, LTCS, etc.)
• RTJ/RF flange options
• required certifications and documentation

This makes Petronash a strong partner for project-specific valve and piping accessory supply.

Yes. Petronash can supply Y Strainers:

• as standalone pipeline components, or
• integrated as part of packaged systems and skids

This reduces site rework and ensures correct selection for flow, pressure, and filtration requirements.
