DIN Y Type Strainer Pressure Rating Comparison: PN16 vs PN25 vs PN40
| Pressure Rating | Design Pressure (bar) | Design Pressure (psi) | Typical Application |
|---|---|---|---|
| PN16 | 16 | 232 | Instrument lines, steam tracing, general small bore piping |
| PN25 | 25 | 362 | Medium-pressure steam, process water, chemical service |
| PN40 | 40 | 580 | High-pressure steam, boiler feedwater, small bore process piping |
Reference: DIN EN 1092-1. PN16 is the standard rating for A105N forged Y strainer small bore service. PN25 and PN40 are available for higher pressure requirements.
A105 vs A105N vs A350-LF2 Material Comparison
| Material | Standard | Key Characteristic | Typical Application |
|---|---|---|---|
| A105N | ASTM A105 | Normalized forged carbon steel | High-pressure small bore piping, instrument lines |
| A105 | ASTM A105 | Forged carbon steel | General small bore piping, non-critical service |
| A350-LF2 | ASTM A350 | Low-temperature forged carbon steel | Low-temperature service down to -46°C |
Reference: ASTM A105, ASTM A350. A105N is the normalized version of A105, offering higher strength and better toughness for high-pressure small bore service. A350-LF2 is selected for low-temperature applications.

A105N DIN PN16 BW Y Type Strainer Applications
• High-pressure instrument lines: small bore impulse and instrument piping in European standard projects requiring PN16 rating.
• Steam tracing and sampling: steam tracing lines, sample systems and analyzer protection with forged A105N body.
• Chemical injection: chemical and inhibitor injection lines requiring small bore forged strainer with BW ends.
• Small bore piping: DN15 to DN50 piping in DIN standard systems where a permanent welded connection is preferred.
• General industrial service: water, gas, oil and steam service in small bore piping with BW ends.
• European standard projects: DIN PN16 piping systems requiring EN 12627 BW end dimensions.
FAQ - A105N DIN PN16 BW Y Type Strainer
Q1: What is an A105N DIN PN16 BW Y Type Strainer?
A: An A105N DIN PN16 BW Y Type Strainer is a forged carbon steel Y strainer with a body made from A105 / A105N material, rated to DIN PN16 or above. It features Butt Weld (BW) ends to EN 12627, a bolted cover with drain plug, and is designed for small bore piping from DN15 to DN50. It is the standard choice for high-pressure instrument lines, steam tracing and small bore piping in European standard projects.
Q2: What is the difference between A105 and A105N?
A: A105 is the standard forged carbon steel grade per ASTM A105. A105N is the normalized version of A105, with a normalizing heat treatment that refines the grain structure, improves toughness and ensures more uniform mechanical properties. For high-pressure small bore strainer bodies, A105N is preferred because it offers higher strength and better resistance to thermal shock and impact. Both materials are suitable for PN16 service, but A105N is selected for critical high-integrity applications.
Q3: Why choose BW ends instead of flanged ends?
A: Butt Weld (BW) ends provide a permanent, leak-tight welded connection with no potential leak path, making them ideal for high-integrity small bore piping and high-pressure service. BW ends also reduce weight and space compared to flanged ends, and are less prone to vibration loosening. For DN15 to DN50 small bore piping, BW ends are commonly specified for instrument and steam tracing lines. Flanged ends are available on request for applications where the strainer needs to be removed periodically.
Q4: What is the size range and pressure rating available?
A: A105N DIN PN16 BW Y strainers are available from DN15 to DN50. Pressure rating is PN16 as standard, with PN25 and PN40 available on request. End dimensions are to EN 12627; face-to-face dimensions follow EN558 and ASME B16.10. The strainer is mounted in the pipeline by butt welding, and the bolted cover allows screen removal for cleaning or replacement without disconnecting the pipeline.
Q5: What screen materials and mesh sizes are available?
A: Screens are supplied in stainless steel SS304, SS316, SS316L and DSS. Perforated hole sizes include 1mm, 2mm and 3mm; wire mesh sizes include 10, 20, 40, 60, 80 and 100 mesh. For general small bore piping and steam tracing, 1mm to 2mm perforated plate or 20 to 60 mesh wire mesh is common. Combined screens (perforated plate + wire mesh) are available for high dirt load with fine filtration requirement. Please specify the screen material and mesh size when requesting a quotation.
Q6: How do I maintain an A105N DIN PN16 BW Y strainer?
A: Maintenance is simple: isolate the strainer, depressurize, remove the bolted cover, take out the screen, clean or replace it, install a new gasket (graphite + stainless steel), and reassemble. The Y-shaped forged body allows screen removal without disconnecting the pipeline. For BW end connection, the strainer body remains welded in the pipeline; only the cover is removed for maintenance. Screen replacement is recommended when the pressure drop exceeds the initial clean-screen value by 0.5-1.0 bar.
