ASTM 2” 150LB WPB RF Flange Basket Strainer

I. Product Overview

TIANYU 2” 150LB RF flange filter is a robust industrial filtration solution engineered to protect pipeline systems from particulate contamination. Constructed with a WPB carbon steel body (per ASTM standards) and featuring a raised face (RF) flange connection, it efficiently removes debris, rust, and solid particles from media such as water, oil, gas, and low-viscosity fluids. Designed to operate at 150LB (2.0MPa) and temperatures up to 300℃, this filter balances durability, ease of maintenance, and high flow capacity—ideal for industrial pipelines, HVAC systems, and process lines where equipment protection and uninterrupted flow are critical.

Product Overview

III. Feature Description

High-Capacity Filtration: The 2” filter houses a large-volume stainless steel basket with a perforated base and mesh lining, capturing particles while maintaining high flow rates. A 40-mesh basket (425μm) efficiently removes rust flakes, pipe scale, and debris in water lines, preventing damage to downstream equipment like pumps, valves, and meters.

WPB Carbon Steel Durability: WPB (welded pipe, bending) carbon steel is hot-rolled and normalized, providing excellent structural integrity under 150LB pressure. Its resistance to mechanical stress makes it suitable for industrial environments with vibration or pressure fluctuations, such as compressor discharge lines.

RF Flange Integration: The raised face flange design creates a secure seal with companion flanges, using gaskets (e.g., non-asbestos, rubber) to prevent media bypass. This ensures all fluid passes through the filter element, eliminating unfiltered flow that could compromise system performance.

Quick-Open Cover: Equipped with a bolted or clamp-style cover for easy access to the filter basket. Maintenance teams can remove and clean the basket in minutes, reducing downtime compared to welded designs—critical for continuous-process industries like food and beverage.

Pressure Drop Optimization: The basket’s open-area design (≥50% of pipe cross-section) minimizes pressure loss, typically ≤0.07MPa at maximum flow. This avoids energy waste in pump systems and ensures consistent flow in HVAC or process lines.

IV. Manufacturing Processes

Body Fabrication: WPB carbon steel plates are cut, rolled, and welded to form the filter body, with flange ends forged or welded per ASME B16.5. Post-welding heat treatment (annealing at 600-650℃) relieves internal stresses, preventing deformation under pressure.

Filter Basket Production: Stainless steel sheets are laser-cut to form perforated bases (1-3mm holes) and wrapped with mesh (woven or sintered). The basket is seam-welded for durability, with a handle for easy removal during cleaning. Mesh size is verified via micrometer testing to ensure particle retention accuracy.

Assembly: The basket is fitted into the body with a sealing O-ring (nitrile rubber for oil resistance, EPDM for water) to prevent bypass. The cover is bolted with a gasket, and flange faces are machined to Ra ≤3.2μm for tight sealing.

Testing: Each filter undergoes:

- Hydrostatic Test: 1.5×150LB (3.0MPa) for 30 minutes to check body and flange integrity.

- Flow Test: Verification of pressure drop at rated flow (e.g., 100m³/h for 2” size) to ensure compliance with design specifications.

- Filtration Efficiency Test: Particle challenge testing with standardized contaminants to confirm mesh performance.

V. Product Advantages

Equipment Protection: By capturing particles as small as 75μm, the filter prevents wear on pumps, valves, and nozzles. In a manufacturing plant case study, installing TIANYU filters reduced pump maintenance by 40% by eliminating debris-induced impeller damage.

Cost-Effective Performance: WPB carbon steel offers lower material costs than stainless steel, making it ideal for non-corrosive media (e.g., water, air, light oils) without sacrificing durability. This balances performance and budget in commercial buildings or industrial facilities.

Easy Maintenance: Quick-access covers and reusable baskets reduce lifecycle costs. Unlike disposable filter cartridges, the stainless steel basket can be cleaned hundreds of times, cutting waste and replacement expenses.

Versatile Compatibility: Works with diverse media—water (potable, industrial), hydraulic oil, natural gas, and low-viscosity chemicals. Optional 316 baskets extend compatibility to mild acids or saltwater applications.

Regulatory Compliance: Meets ASTM and ASME standards, ensuring suitability for industries with strict requirements (e.g., pharmaceutical water systems, where particle control is critical for product purity).
