Industrial Stainless Steel Conical Strainers (Witch Hat Strainers) by FlowBiz
During plant startup, system commissioning, or continuous operations, pipeline debris such as weld slag, scale, rust, and construction waste can severely damage downstream equipment like pumps, control valves, and meters. FlowBiz Conical Strainers (Witch Hat Strainers) provide an effective, cost-efficient solution to capture particulate solids and safeguard critical process machinery.
Designed for installation between standard pipe flanges, these temporary and permanent strainers feature high open-area ratios to minimize pressure drops while offering high filtration efficiency. Manufactured using high-grade stainless steel wire mesh and perforated sheets, FlowBiz conical strainers withstand heavy flow velocities and differential pressures.
Technical Specifications & Features
FlowBiz conical strainers are precision-engineered to meet diverse industrial pipeline requirements:
- Strainer Type: Conical Strainer / Witch Hat Strainer / Temporary Flange Strainer
- Material of Construction (MOC): Stainless Steel (SS304 / SS304L / SS316 / SS316L) & Exotic Alloys on demand
- Element Construction: Precision-punched perforated sheet outer cone with optional inner/outer wire mesh lining for fine filtration
- Flange Ring Design: Raised Face (RF) or Flat Face (FF) mounting ring designed to fit ANSI, DIN, and BS standard flange specifications
- Flow Direction: Available for both Inside-to-Outside and Outside-to-Inside flow configurations
- Pressure Drop Optimization: Engineered with open-area ratios ranging from 150% to 300% of the pipe cross-sectional area to prevent pressure losses
