Description
Conical Type Strainer Manufacturer & Exporter in India
FlowBiz Conical Type Strainers (commonly known as Witch's Hat Strainers or Temporary Strainers) are specialized inline filtration elements engineered primarily for plant startup, commissioning, and temporary pipeline purging operations. Installed directly between standard pipe flanges, these conical strainers intercept construction debris, welding slag, rust, and pipe scale before initial fluid circulates into sensitive downstream equipment such as turbines, compressors, and high-pressure pumps.
Unique Mechanical Engineering & Operational Features
- High Net Open-Area Ratio: Designed with a 3:1 to 5:1 open area ratio relative to the pipe cross-section, providing high dirt-holding capacity while maintaining extremely low differential pressure drops.
- Inline Flange-Clamped Installation: Fits neatly between two standard ASME/ANSI B16.5 flanges with custom-machined handle rings that extend outside the flange connection for easy visual identification and quick removal.
- Bi-Directional Flow Configurations: Available in both Cone Point Upstream (debris collected inside the cone for easy cleanout) and Cone Point Downstream (debris collected on the exterior cone surface) designs based on flow velocity and pipe orientation.
- Reinforced Heavy-Duty Construction: Built with heavy-gauge perforated stainless steel backer sheets and fine wire mesh linings to withstand maximum differential pressure spikes without collapsing.
