The stainless steel temporary strainer is essential during the pipeline commissioning start-up phase across industries like oil and gas, chemical processing, or water treatment. These temporary strainers help prevent costly damage by filtering out construction debris, welding slag, rust, and other particles before they can enter sensitive downstream equipment.

What Are Stainless Steel Temporary Strainers?
Stainless steel temporary strainers are removable inline filters used during the pre-operational phase of pipeline systems. Installed between flanges or within pipework, they provide short-term filtration to protect pumps, valves, meters, and other critical components during system start-up.

Once the pipeline is clean and stable, these commissioning strainers are typically removed or replaced with permanent filtration solutions.

Key Features and Types of Temporary Strainers
Temporary strainers are often manufactured using perforated stainless steel or welded mesh, ensuring strength and corrosion resistance across various fluids and pressures. Common types include:
• Temporary cone strainers(nicknamed witch hat strainers): Shaped like a cone or truncated cone, these strainers are inserted into flanged joints and are ideal for capturing large particles during initial flushing.
• Temporary Basket Strainers: These provide greater debris-holding capacity and are suitable for high-flow systems.
• Temporary Plate Strainers: Flat disc filters used where space is limited and lower pressure drops are required.

All types are made from stainless steel, offering durability, chemical resistance, and compatibility with ANSI or ASME standard flanges.

Why Use Temporary Strainers for Pipeline Commissioning?
During pipeline commissioning, it’s common for residual debris from construction, welding, and handling to be present in the system. If not removed, these particles can damage:
Pumps and compressors
Valves and actuators
Flow meters and instruments
Heat exchangers and filters

Stainless steel temporary strainers act as a first line of defense, removing contaminants before permanent equipment is exposed. This protects assets and ensures system performance and reliability once operations begin.

Temporary Strainer Applications Across Industries
Temporary strainers are used wherever pipeline start-up and system flushing are required. Common industries include:
• Oil & Gas: For upstream and downstream process pipelines
• Petrochemical Plants: During the commissioning of process piping
• Water Treatment: To clean raw water intake and distribution pipelines
• HVAC Systems: For protecting chillers, pumps, and valves during start-up
• Power Generation: To ensure clean circulation in the turbine feed lines
• Chemical Processing: Where clean flow paths are vital for batch production

Benefits of Stainless Steel Temporary Strainers
• Durable Construction: Stainless steel withstands high pressure, corrosion, and temperature variations
• Efficient Debris Removal: Customizable mesh or perforation sizes filter fine or coarse particles
• Easy Installation and Removal: Designed to fit between flanges, simplifying maintenance and replacement
• Cost-Effective Protection: Prevents major damage during a critical operational phase
• Compliance with Industry Standards: Built to ANSI, ASME, or customer specifications

Selecting the Right Temporary Strainer
Choosing the correct temporary strainer depends on:
Pipeline size and pressure rating
Type of fluid and temperature range
Debris load and particle size
Installation space and flange compatibility
