What Is a Witches Hat Strainer? Cone Strainer Guide for Pipeline Filtration A witches hat strainer , also known as a cone strainer or conical filter , is a temporary filtration device used in pipelines to remove unwanted debris during system startup. It is widely used in industries such as oil and gas, water treatment, and chemical processing to protect downstream equipment. How Does a Cone Strainer Work? The cone strainer is installed between pipe flanges. As fluid flows through the pipeline, solid particles are trapped by the mesh or perforated surface, allowing clean fluid to pass through. Types of Cone Strainers Wire mesh cone strainer (fine filtration) Perforated cone strainer (coarse filtration) Hybrid cone strainer (combined structure) Why Use a Witches Hat Strainer? Prevents equipment damage Reduces maintenance costs Ensures smooth system startup Flow Direction of Cone Strainers The recommended installation is with the cone tip facing upstream. This improves filtration efficie...

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. What Are Wire Mesh and Perforated Temporary 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 ...
