FlowBiz Temporary Strainers – Cone, Basket & Flat Plate Types for Pipeline Start-Up & Commissioning

During initial plant start-up, pipeline commissioning, and line flushing across chemical processing, oil refining, and gas transport facilities, loose debris like welding slag, mill scale, thread cuttings, and rust pose a major threat to downstream equipment. The FlowBiz Temporary Strainer Series provides versatile, high-strength temporary inline filtration inserted directly between standard pipe flanges to protect sensitive pumps, control valves, flow meters, and heat exchangers.

Engineered to fit standard ASME B16.5 raised-face flanges, FlowBiz manufactures three distinct temporary strainer geometries—Cone Type, Basket Type, and Plate Type—to accommodate varying flow velocities, space constraints, and debris load profiles. Each strainer features an extended, laser-marked indicator paddle that protrudes beyond the flange insulation, providing clear visual identification for maintenance crews during post-commissioning line inspections.

Technical Specifications & Configurations

FlowBiz Temporary Strainers are fabricated to exact ASME, DIN, and project specifications:

Key Applications Across Industrial Utilities

FlowBiz Temporary Strainers are installed across critical commissioning environments:

  • Oil Refineries & Petrochemical Plants: Traps pipe scale, rust, and weld beads during initial hydrocarbon header flushing.
  • Power Generation & Boiler Units: Safeguards steam turbines, feed pumps, and condenser lines during pre-operational steam blows.
  • Chemical Processing Facilities: Protects pump impellers, flow meters, and control valve seats during solvent line testing.
  • Cross-Country Pipelines & Gas Terminals: Captures construction dirt and debris in natural gas, crude oil, and product transfer lines.

Why Choose FlowBiz Exports Pvt. Ltd.?

The FlowBiz Temporary Strainer range delivers key mechanical and operational benefits:

  • Versatile Geometry Options: Choice of Cone, Basket, or Plate designs ensures a precise match for pipeline velocity and space limitations.
  • Heavy-Duty Welded Construction: Full-penetration welded seams prevent screen collapse or deformation under high differential pressures.
  • Precision Surface Finish: Passivated stainless steel construction offers excellent resistance to atmospheric and chemical corrosion during flushing.
  • Clear Visual Tracking: Integrated paddle handles serve as a permanent visual indicator to remind engineers to remove temporary strainers after commissioning is complete.
