FlowBiz Temporary Cone Strainer – Pipeline Commissioning & Debris Protection for Natural Gas Systems

During plant commissioning, pipeline tie-ins, and start-up operations in natural gas processing, glycol dehydration units, and gas distribution lines, construction debris like weld slag, rust, pipe scale, and sand can cause severe damage to downstream compressors, control valves, and contactor towers. The FlowBiz Temporary Cone Strainer (commonly referred to as a "Witch's Hat" strainer) provides a cost-effective, high-strength temporary filtration solution installed directly between standard pipeline flanges.

Featuring a heavy-duty single welded assembly consisting of a flat ring plate handle (paddle) and a perforated metal cone, this strainer traps foreign particulates from the upstream gas stream. Engineered to withstand high pressure differentials without basket collapse, the FlowBiz Temporary Cone Strainer safeguards critical infrastructure like glycol contactor towers, reboilers, and burner management systems during initial plant flushing and commissioning phases.

Key Applications Across Gas Processing Utilities

The FlowBiz Temporary Cone Strainer delivers crucial initial protection across gas and petrochemical processes:

• Natural Gas Dehydration Units: Protects glycol contactor towers, circulation pumps, and reboilers from pipeline mill scale and weld spatter.
• Compressor & Turbine Intake Headers: Prevents loose construction debris from entering high-speed gas compressor impellers and gas turbines during start-up.
• Gas Metering & Pressure Reduction Skids: Safeguards delicate turbine meters, ultrasonic flow meters, and control valve seats during initial pipeline blowdown.
• Burner Management Systems (BMS): Filters fine scale and rust to prevent clogging of fuel gas burner nozzles and pilot lines.

Why Choose FlowBiz Exports Pvt. Ltd.?

The FlowBiz Temporary Cone Strainer offers vital safeguards for temporary and commissioning filtration:

• High Mechanical Strength: Precision-welded cone geometry withstands high differential pressures without tearing or bursting during heavy debris accumulation.
• Easy Identification: The extended flat ring plate handle (paddle) allows operators to easily identify and remove temporary strainers once the pipeline flushing phase is complete.
• Low Initial Investment: Provides an economical alternative to permanent cast/fabricated Y-strainers during temporary plant Flushing and Cleaning (F&C) operations.
• Customizable Open Area Ratios: Engineered with open area ratios from 150% to over 300% of the pipe cross-sectional area to minimize pressure drop across the filter element.
