Temporary Cone Strainer is a cone-shaped metal filter installed inside a pipeline flange connection. It acts as a temporary barrier that captures debris during the early stages of pipeline operation. Because it is mounted between two flanges, it can be installed and removed quickly without major modifications to the pipeline.

Key Features of Temporary Cone Strainers

1. Cone-Shaped Design: The conical shape increases the filtration area and allows debris to accumulate without immediately blocking the flow.

2. Temporary Installation

Pipeline commissioning

Equipment startup

System flushing

3. Easy Installation and Removal: They are simply placed between pipeline flanges, making them easy to install and remove once the system is clean.

4. High Strength Materials

Stainless steel

Carbon steel

Alloy steel

Common Types of Temporary Strainers

1. Cone Strainer: Cone-shaped design, Installed with the cone pointing upstream or downstream depending on the application, Suitable for large pipelines

2. Basket Strainer: Basket-shaped temporary filter, Used where larger debris collection capacity is required

3. Plate Strainer: Flat perforated plate, Used for simple filtration with minimal pressure drop

Typical Applications

Oil and Gas: Protect pumps and compressors from welding slag and pipe scale.

Chemical Processing: Prevent contaminants from entering sensitive equipment.

Power Plants: Used during commissioning of steam and water pipelines.

Water Treatment Systems: Capture debris before water reaches pumps and valves.

Temporary cone strainers can be customized with

Different mesh sizes for specific filtration requirements

Perforated plate or wire mesh combinations

Handles or lifting lugs for easy removal

Flow direction markings
