Introduction to Strainers

A strainer is a mechanical device used in pipelines to remove unwanted solids from liquids, gases, or steam. It protects downstream equipment—such as pumps, valves, and meters—from damage caused by debris or particulates.

How It Works

• Fluid enters the strainer body and passes through a perforated or mesh screen.

• The screen traps solid particles while allowing clean fluid to flow through.

• The collected debris can be removed by cleaning or replacing the screen.

Key Features

• Protective Function: Prevents clogging and wear in sensitive equipment.

• Simple Design: Easy to install and maintain.

• Versatile Use: Suitable for water, oil, gas, steam, and chemical systems.

• Customizable Filtration: Screens available in various mesh sizes and materials.

Limitations

• Pressure Drop: Can increase as debris accumulates.

• Maintenance Required: Screens must be cleaned or replaced regularly.

• Not for Fine Filtration: Not suitable for removing microscopic particles.
