Filter and Strainer

Strainer

As the marketplace becomes increasing competitive, more emphasis has been placed on reducing plant downtime and maintenance. In steam and condensate system, damage to plant is frequently caused by pipeline debris such as scale, rust, jointing compound, weld metal and other solids in flowing liquids or gases, and protect equipment from their harmful effect, thus reducing downtime and maintenance. A strainer should be fitted upstream of every steam trap, flowmeter, and control valve

Filter
Whilst strainers remove all visible particles in the steam, it is some tomes necessary to remove smaller particles, for example in the following application
• Where there is direct injection of steam into a process, which may cause contamination of the product.
Example: In the food industry and for the sterilization of process equipment in the pharmaceutical industry.
• Where dirty steam may cause rejection of a product or process batch due to staining or visible particle retention.
Example: Sterilizers and paper/board machines.
• Where minimal particle emission is required from steam humidifiers.
Example: Humidifier used in a clean environment.
• For the reduction of the water content, ensuring a dry, saturated supple.
In such clean steam application, strainers are not suitable and filter must be used.
