Temporary Strainer | Conical Strainers
Temporary strainers are available in various shapes and sizes, commonly referred to by different names such as conical strainers, cone strainers, witches hat strainers, plate type strainers, and temporary basket strainers.
Conical Strainers
Conical strainers, characterized by their cone shape, are woven mesh devices designed to capture particles within a pipeline. They can effectively trap particles as small as 0.001 inches (25 microns) in diameter and feature minimal pressure drop. These strainers can be easily removed for maintenance. The screen cone is often soldered around the entire circumference of the flange ring to enhance strength and prevent unwanted bypass.
Importance of Temporary Strainers
All new plumbing systems should incorporate temporary strainers at the start of a pipeline. These removable strainers typically have a large screen and come in nominal pipe sizes ranging from 1/4” to 50”. The open area ratio of the strainer to the pipe’s cross-section generally falls between 100% and 300%. Material thickness for strainers varies from 22 to 11 gauge, depending on the size of the holes.
Types of Temporary Strainers
- Temporary Basket Strainers: These usually utilize perforated plates as their filtering medium.
- Cone Type Strainers: These eliminate visible debris while allowing small liquid waste to pass through. They can be cleaned manually by shutting off the drain and removing the filter cap.
- Plate Type Strainers: These consist of a flat mesh that is oriented perpendicular to the flow of the system.
Fabricated Temporary Strainers
We provide temporary pipeline strainers in various designs including cone, basket, or plate types. While they assist in startup processes, cone strainers should not serve as permanent solutions; alternatives like y-strainers, basket strainers, tee strainers, or duplex basket strainers are recommended. Temporary cone or basket strainers can be constructed from different metals and customized to any length, with standard lengths being either 100% or 150%. The open area is measured based on these lengths.
Sizes and Materials
Standard sizes range from 1″ (25mm) up to 24″ (600mm), with larger sizes available upon request. Common materials include stainless steel, carbon steel, Monel, and Hastelloy.
Applications
Temporary strainers find use across various industries including:
- Process Industry
- Water and Wastewater Management
- Power Generation
- Pulp and Paper Production
- Chemical Processing
- Marine Applications
- Oil and Gas Industry
- Steel Manufacturing
- Metals and Mining
This comprehensive overview highlights the significance and versatility of temporary strainers in various industrial applications in Mumbai.
