Temporary Strainer

Starting up a new piping system or bringing equipment online after maintenance? It's a critical phase, but one often fraught with hidden dangers – namely, leftover debris. Welding slag, stray tools, wood fragments, rocks, and other construction remnants can wreak havoc if allowed to flow downstream. 

This is where temporary strainers become indispensable protectors.

At YUBO Filtration Company, we specialize in designing and manufacturing the precise straining elements needed to ensure a smooth, safe startup.

YUBO has the experience to design and build the straining element you need! Your fabricated Temporary strainer can be provided with specialty perforations and meshes, Dutch weave meshes, wedge wire screens, pleated straining elements, etc.

What Are Temporary Strainers?

A temporary strainer is a startup strainer, also known as a conical or basket strainer, and is installed in a system to remove unwanted debris from the process stream.

They typically come in several shapes to suit different installation points, most commonly:

Cone (Witches Hat) Strainers: Fit snugly between flanges.

Basket Strainers: Offer a larger surface area for debris collection.

Plate Strainers: Simple, flat screens for basic protection.

Why Are Temporary Strainers So Crucial During Startup?

Imagine the damage a stray piece of welding rod or a small rock could do if it slammed into a delicate flow meter sensor, lodged itself in a control valve seat, or got drawn into a pump impeller. The consequences range from inaccurate readings and component malfunction to catastrophic equipment failure and costly downtime. Temporary strainers act as the first line of defense, protecting vital and expensive equipment like:

• Pumps

• Flow Meters

• Control Valves

• Relief Valves

• Other sensitive instruments

By capturing debris before it reaches these components, startup strainers ensure the system begins operation cleanly and safely. Once the system is flushed and running debris-free, these strainers are typically removed.

Choosing the Right Temporary Strainers: Materials and Design

Selecting the appropriate temporary strainer depends heavily on the process fluid and operating conditions. Material compatibility is key to prevent corrosion or degradation. Common, reliable materials include:

• Stainless Steel: Grades like 304, 306, and 306L offer excellent corrosion resistance for a wide range of applications.

• Wedge Wire Screens (V-Wire): Provide robust construction with precise slot openings and resistance to clogging.

Beyond the base material, the actual straining element design is critical. 

YUBO offers a wide array of options:

• Specialty Perforations: Custom hole sizes and patterns.

• Woven Meshes: Including fine Dutch weave meshes for specific particle retention.

• Pleated Elements: Maximize surface area within a compact space.

• Wedge Wire Screens: As mentioned, known for strength and precision.

Need help determining the optimal perforation size, mesh count, or screen type for your specific needs? The YUBO team is ready to assist, ensuring you get the right level of filtration without unnecessary pressure drop.

Beyond Temporary: Custom and Permanent Solutions

While most startup strainers serve a short-term role, some situations require a permanent installation or a highly specialized design. Perhaps access is difficult for removal, or ongoing protection is deemed necessary.

YUBO thrives on these challenges. Our in-house design and fabrication facilities allow us to rapidly create custom straining solutions tailored to unique applications. Whether you need a modified standard design or a completely bespoke strainer, we can meet demanding specifications and urgent timelines.
