Temporary Strainer

Temporary Pipeline Strainers
Filson temporary pipeline strainers are essential for the start-up of any new or revamped pipeline systems. They deliver the superior filtration performance thereby guaranteeing the damage-free downstream equipment.
Temporary Strainer Pump Suction 
Filson temporary strainer pump suction commonly can be installed within the first 5 ft. (1.5 meters) upstream of a pump to protect subsequent devices. If there is persistent fouling or debris in the pumped fluid, please arrange a permanent Y or T strainer for long-term pump protection.
Temporary Cone Strainer 
Filson temporary cone strainer, or you could call it temporary cone strainer, witches hat strainer, temporary conical strainer, is a kind of temporary device for short period system startup with cone shape. It benefits chemical, petroleum, power generation and marine industries.
Temporary Basket Strainer
Filson temporary basket strainer has less volume and surface area than cone strainers resulting in a slightly higher pressure drop. Perforated plate is the most used media and the perforation holes usually sizing from 1/32 to 1/2 inches.

Filson temporary strainer can be manufactured in a range of materials including stainless steel, carbon steel, Monel, Hastelloy, among the most commonly used is SS 304/316 type. Material of construction should be compatible with the fluid.

Temporary Pipeline Strainers

Furthermore, Filson temporary strainers are available in cone, basket, and plate shapes to satisfy diverse applications. Among Filson temporary basket strainer features slightly higher pressure loss than cone strainer, while the plate one shows the highest pressure drop.

Filson stocks abundantly of standard Filson temporary strainers which are fabricated by wire mesh, perforated plate, sintered mesh, pleated mesh. Please pay more attention to the viscosity, flow rate, corrosiveness, temperature, and pressure drop of your liquid before you select.

To suit your existing system without any deviation, Filson temporary strainer dimensions are optional in actual manufacturing. You can refer to our standard technical data to choose from, or send us your independent sizes to custom.

In addition, Filson temporary strainers can be designed with raised face(RF) flanges, flat face(FF) flanges or ring-type joint(RTJ) flanges to facility your installation. Other matching accessories are also supplied which will come with your main startup strainer, and do not hesitate to contact us if you need any spare parts.

Not only the strong manufacture ability, Filson also has strong design capability for every customized order. We excel at designing CAD drawings of various temporary strainers based on your installation requirements and can modify specific sizes for the best system suitability.

Filson temporary strainers installation have two usual styles, the strainer tip points upstream or points downstream. This depends on which direction there is sufficient installation space for the length of Filson temporary strainer, or is up to your preferred flow direction if without space limit.

However, if you desire the latter installation type, we recommend that you are better off with the enhanced temporary strainers like sintered cone strainers or a cone strainer with support mesh layer/frame. So that it can be strong enough to resist the risk of being rip apart since the heavy strain created when debris collect inside.

Filson temporary strainers are only applicable for short periods of commissioning of the existing system or pilot runs of new systems as the name implies. It is hardly capable of any long-term filtration tasks thus you’ll need to replace it with a permanent strainer after temporary use.

Certainly Filson can also supply basket filters, Y-strainers, T-strainers, and duplex basket strainers for permanent straining. If you have any needs, Filson is happy to provide a complete solution for you.

During normal operation, clogging of Filson temporary strainer is inevitable and that will result in pressure drop increasing. Typically when pressure drop exceeds 5-10 psi, you are recommended to promptly remove and clean the strainer.

Caution: make sure that the pressure level inside the pipeline near the strainer has been reduced to atmospheric pressure level before removing the temporary strainer, failure to do so poses a safety risk to operator.
