Plate Type Temporary Strainer
Introduction
During initial commissioning, plant startup, or post-maintenance flushing, industrial pipelines often carry construction debris such as welding slag, pipe scale, rust, and gaskets. Leaving these foreign particles in the stream can cause catastrophic damage to expensive downstream equipment like pumps, control valves, meters, and turbines. The Plate Type Temporary Strainer provides an economical, space-saving protection barrier designed for short-term filtration during critical operational phases. FlowBiz Exports supplies Plate Type Temporary Strainers to safeguard pipeline integrity across process plants in India and abroad.
Product Overview
A Plate Type Temporary Strainer—also known as a flat plate strainer or paddle-type temporary strainer—consists of a flat metallic plate with a perforated central filtration zone and an extended handle/indicator tab. Installed directly between two standard mating pipe flanges using gaskets, its extended handle protrudes beyond the flange diameter to visually signal to operators that a temporary strainer is installed in the line. Once commissioning is completed and the pipeline is thoroughly flushed, the strainer can be removed or replaced with a permanent spacer ring.

Key Features
- Compact Flat Profile: Compact disc construction allows easy insertion directly between existing pipe flanges without altering line dimensions.
- Extended Indicator Tab: The built-in handle tab remains clearly visible outside the flange joint, alerting operators to its presence in the line.
- Corrosion-Resistant Materials: Manufactured using stainless steel alloys (SS304/SS316) to ensure media compatibility and structural integrity under flow velocity.
- Customizable Perforation Sizes: Available in various hole diameters and mesh overlays to catch specific particulate sizes during flushing.
- Cost-Effective Protection: Provides a low-cost insurance policy for downstream pumps, valves, and measuring instruments during system commissioning.
Applications
- Plant Commissioning & Startup: Installed in newly constructed oil, gas, chemical, and power pipelines to collect construction debris.
- Post-Maintenance Flushing: Placed ahead of sensitive instruments following system overhauls, welding, or line modifications.
- Pump & Turbine Protection: Temporary inline protection during trial runs and initial fluid circulation phases.
- Refineries & Petrochemical Lines: Trapping scale and debris during initial hydrocarbon filling or chemical flushing operations.
Benefits
- Equipment Damage Prevention: Prevents severe mechanical damage to control valve seats, impellers, and flow meter sensors during line start-up.
- Space-Saving Installation: Requires zero special housing or extra pipe length, unlike permanent Y-strainers or basket strainers.
- Clear Operational Visibility: Protruding tab prevents accidental leaving of temporary strainers in line after flushing is completed.
