Temporary Conical Strainers for Coarse Filtration in Industrial Piping

Temporary conical strainers are a vital tool for efficient filtration in various pipeline systems, particularly during system start-ups or maintenance periods. These strainers are designed to provide temporary yet effective protection by filtering out coarse contaminants from fluids, such as gas, oil, steam, and water. Their simple, cone-shaped structure allows for quick installation between pipeline flanges, ensuring immediate inline protection for the system.

Also known as witch's hat or temporary cone strainers, these conical strainersare widely used across industries to maintain fluid purity and protect sensitive equipment from debris or particulate buildup. The compact, user-friendly design ensures that systems can run smoothly and safely while minimizing the risk of costly damage or downtime.

Key Features and Benefits

1. Ease of Installation and Maintenance 

Temporary conical strainers are designed for quick and easy installation between pipeline flanges. Their simple construction allows for immediate deployment, making them ideal for temporary filtration needs during system start-ups or when maintenance is required. Furthermore, they are easy to maintain, with a removable cartridge that simplifies cleaning and reinstallation, allowing the strainer to stay functional with minimal downtime.

2. Effective Filtration of Impurities 

These strainers play a critical role in ensuring that only clean fluids pass through the system. Positioned typically at the inlet ports of valves such as relief, decompression, or water level valves, the conical strainer traps larger particulates, preventing damage to downstream equipment. This process promotes smoother, more stable operation in industrial systems and helps maintain the overall integrity of the pipeline.

3. Durable and Versatile Construction 

Temporary conical strainers come in a variety of configurations to suit different filtration needs. The construction typically includes perforated metal for robust filtration, woven wire mesh for fine filtration, or a combination of both to provide enhanced efficiency. These strainers can also feature multilayer wire cloth or additional internal supports, offering versatility in addressing specific industrial demands.

The strainer’s design allows for different media construction, such as:

Single-layer perforated metal mesh without inner wire cloth

Single-layer woven wire cloth for fine filtration

Multilayer wire cloth for more intricate filtration needs

This flexibility ensures that users can select the right solution for their specific filtration requirements.

Applications and Industrial Use

Purification of Pipeline Fluids Temporary conical strainers are essential in removing impurities from various pipeline fluids, including gas, oil, steam, and water. By filtering out contaminants, they ensure that only clean fluid flows through the system, helping to protect valves, pumps, and other sensitive equipment. This contributes to more efficient and stable industrial operations.

Industries and Processes Temporary conical strainers are widely used in industries that process fluids with solid particles. These include pharmaceuticals, chemicals, food production, and pesticides, where the filtration of contaminants is critical. In particular, they are invaluable for processes such as boiling, drying, conveying, and filtering. The use of conical strainers ensures that contaminants are removed before they can compromise the quality of products or disrupt processes.

In all, stainless steel temporary conical strainers are an essential component for maintaining the efficiency and safety of industrial pipeline systems. Their simplicity, ease of installation, and effective filtration capabilities make them an excellent choice for various industries, ensuring that systems operate smoothly and free from contaminants.
