In the demanding environments of industrial filtration, precision and reliability are non-negotiable. Whether in the oil and gas industry, chemical processing, or water treatment, temporary filtration plays a crucial role during system start-ups and commissioning. At the forefront of these applications are wire mesh and perforated temporary filters, particularly the witches hat strainers, also known as temporary cone strainers or cone mesh filters.
Temporary filters are designed for short-term protection of pipelines and equipment. These filters catch debris, including welding slag, rust, and scale, during system flushing or before permanent filtration is installed.
There are two common types:
• Wire Mesh Temporary Filters: The temporary filters are made of stainless steel wire mesh, offering fine filtration suitable for systems that require protection from small particles. They are often fabricated with multi-layer wire mesh for higher strength and durability.
• Perforated Temporary Filters: These are manufactured using perforated metal cones or baskets. They are ideal for capturing larger contaminants and are commonly used in systems where flow resistance must be minimized.
Ease of installation in pipelines
Low-pressure drop
Cost-effective protection
Reusable and easy to clean
Available in various mesh sizes, including SS304 and SS316 stainless steel
These temporary cone strainers are particularly effective as start-up strainers in high-pressure environments such as boiler systems, power plants, petrochemical pipelines, and hydraulic systems.
Applications Across Industries
Our temporary strainer cones are widely used in:
• Oil and Gas: Protecting pumps, valves, and compressors during flushing
• Chemical Processing: Filtering catalyst fines, resins, and process fluids
• Water Treatment: Removing sediment and solids before permanent filters
• Power Generation: Ensuring clean fluid systems during commissioning
• Desalination Plant: Used for seawater desalination pipeline commissioning
Whether installing a cone strainer for pipelines or needing a temporary filter for flushing, these components are essential for maintaining equipment integrity and operational efficiency.
