Temporary Pipeline Protection Against Welding Slag, Rust & Debris

Our Stainless Steel Conical Temporary Strainers are designed to protect pumps, valves, compressors and other critical equipment during pipeline flushing, commissioning and initial operation.

Installed between pipe flanges, the cone-shaped filter element captures unwanted particles such as welding slag, rust, scale and construction debris before they enter downstream equipment.

With customized mesh size, wire diameter, cone dimensions, flange connection and support structure, we manufacture temporary strainers according to your pipeline requirements.

Why Use a Temporary Cone Strainer?

During pipeline installation and system start-up, contamination is unavoidable.

Common particles include:

--Welding slag

--Rust particles

--Metal chips

--Sand

--Pipe scale

--Foreign materials

These contaminants may cause:

--Pump damage

--Valve failure

--Blockage

--Equipment downtime

--Reduced system reliability

A temporary cone strainer provides a simple and effective protection solution before the system reaches normal operation.

Key Advantages

1. High Flow Capacity

The conical design provides a larger filtration surface compared with flat filter screens, helping reduce pressure drop while capturing debris.

2. Strong Metal Construction

Manufactured from stainless steel wire mesh or perforated metal, the strainer provides reliable strength during pipeline operation.

3. Easy Installation & Removal

Designed for quick installation between flanges and easy removal after pipeline cleaning.

4. Customized Design

Different pipeline sizes, flange standards, mesh openings and support structures can be manufactured according to customer requirements.

5. Reinforced Filter Structure

For higher flow or pressure applications, wire mesh can be combined with perforated metal support to improve durability.

Product Specifications

Mesh & Filtration Options

The filtration performance depends on mesh opening, wire diameter and application requirements.

The correct mesh selection should balance filtration efficiency and pressure drop.

Typical Applications

Pipeline Commissioning

Protects equipment during initial flushing and cleaning.

Pump Protection

Prevents debris from damaging pumps during start-up.

Valve Protection

Captures particles before they reach precision valve components.
