Forged Y Strainer Pressure Rating Comparison: 800LBS vs 900LBS vs 1500LBS
| Pressure Class | Design Pressure (bar) | Design Pressure (psi) | Typical Application |
|---|---|---|---|
| 800LBS | 136 | 1,975 | High-pressure small bore piping, instrument lines, steam tracing |
| 900LBS | 153 | 2,220 | Very high-pressure process, wellhead, gas injection, flanged RF/RTJ service |
| 1500LBS | 260 | 3,750 | Ultra high-pressure small bore, wellhead, hydraulic systems |
Reference: ASME B16.34. 900LBS is the standard high-pressure class for flanged forged Y strainer small bore service. 800LBS and 1500LBS are available for other pressure requirements.
A105 vs A105N Forged Carbon Steel Material Comparison
| Material | Standard | Key Characteristic | Typical Application |
|---|---|---|---|
| A105N | ASTM A105 | Normalized forged carbon steel, higher strength and toughness | High-pressure small bore piping, instrument lines, 900LB flanged service |
| A105 | ASTM A105 | Standard forged carbon steel | General small bore piping, non-critical service |
Reference: ASTM A105. A105N is the normalized version of A105, offering higher strength and better toughness for high-pressure small bore service. A105N is preferred for 900LB flanged forged Y strainers.

High Pressure Flanged Forged Y Type Strainer Applications
• High-pressure instrument lines: small bore impulse and instrument piping in refinery, chemical and power plant requiring 900LB flanged connection.
• Steam tracing and sampling: steam tracing lines, sample systems and analyzer protection with A105N forged body and RF/RTJ flanged ends.
• Chemical injection: chemical and inhibitor injection lines requiring small bore forged strainer with RTJ end for leak-tight sealing.
• Wellhead and oilfield: high-pressure small bore wellhead piping, gas lift and chemical injection with 900LB flanged connection.
• Hydraulic systems: high-pressure hydraulic power systems with 900LB rating for pump and valve protection.
• General small bore piping: 1/2 inch to 2 inch piping requiring flanged forged Y strainer with RF or RTJ ends, at 900LB rating.
FAQ - High Pressure Flanged Forged Y Type Strainer 900LB
Q1: What is a High Pressure Flanged Forged Y Type Strainer?
A: A High Pressure Flanged Forged Y Type Strainer is a Y-shaped pipeline strainer with a forged carbon steel body (A105/A105N), rated to ANSI Class 900LB. It features flanged ends (RF or RTJ) to ANSI B16.5 and is designed for small bore piping from 1/2 inch to 2 inch. The forged body provides higher strength and tighter grain structure than cast body, making it suitable for high-pressure and thermal shock service. It is the standard choice for high-pressure instrument lines, steam tracing and chemical injection in refinery and chemical plants.
Q2: What is the difference between RF and RTJ flanged ends?
A: RF (Raised Face) flanged ends have a raised sealing surface and use a spiral wound or graphite gasket. They are the most common for general high-pressure service and allow easy maintenance. RTJ (Ring Joint) flanged ends use a metal ring gasket that is compressed into a groove between the flange faces, providing a leak-tight metal-to-metal seal. RTJ is preferred for high-pressure and high-temperature service, especially in refinery and gas transmission. For 900LB forged Y strainer, both RF and RTJ are available; RTJ is recommended for critical high-pressure service.
Q3: 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 900LB service, but A105N is selected for critical high-integrity applications.
Q4: What is the size range and pressure rating available?
A: Flanged forged Y strainers 900LB are available from 1/2 inch to 2 inch (DN15 to DN50). Pressure rating is ANSI 900LBS / 900LB. Flange dimensions are to ANSI B16.5. The bolted cover with drain plug allows screen removal for cleaning or replacement without disconnecting the pipeline. Special designs and other materials are available on request.
Q5: What screen materials and mesh sizes are available?
A: Screens are supplied in stainless steel SS304, SS304L, SS316, SS316L and duplex stainless steel. Perforated hole sizes include 1mm, 2mm, 3mm and 5mm; wire mesh sizes include 40, 60, 80 and 100 mesh. For high-pressure small bore piping and steam tracing, 1mm to 2mm perforated plate or 40 to 80 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 a flanged forged Y strainer 900LB?
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 flanged end connection, the strainer body remains bolted 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.
