Product Description
Pipeline Strainer-Filters for pipe-Y type & Basket type Strainer
U-ideal pipeline strainer is a device which provides a means of mechanically removing solids from a flowing fluid. This is accomplished by utilizing a perforated metal, mesh or wedge wire straining element. The most common range of strainer particle retention is 1" to 40 micron (0.0016").
Using Purpose of U-ideal pipeline strianer
Strainers are employed in pipelines to protect downstream mechanical equipment such as condensers, heat exchangers, pumps, compressors, meters, spray nozzles, turbines, and steam traps from the detrimental effect of sediment, rust, pipe scale, or other extraneous debris.
Types of Strainers
Specified strainers are the Y strainer and the basket strainer. While there is primarily one type of Y strainer, there are several variations of basket strainers.
Y Strainer, Basket Strainer
Vertical piping, frequently found at pump inlets, necessitates the use of a Y strainer or a tee type basket strainer. Most basket strainers are intended for horizontal or slightly inclined piping. Special attention must be given to the orientation of the debris collection chamber and the drain (blowdown) connection of the strainer. The strainer must be installed such that 2 it is located at the lowest possible position. For liquid flow a Y strainer in vertical piping must be placed with its screen in the downward position to trap the sediment in the debris collection chamber. For steam service, it is recommended that Y strainers be mounted sideways in horizontal lines to prevent condensate accumulation.
Tee type strainers, suction diffusers and several variations of basket strainers can also be used in a right angle flow application.
Y strainers and most variations of basket strainers can be self-cleaning. With the addition of a blowdown valve and some modification of the straining element of a basket strainer, the element can be flushed out by opening and closing the blowdown valve. This can be accomplished without flow stoppage or disassembling any piping. In sizes above 4", a single basket strainer will generally create less pressure drop than a Y strainer. Basket strainers are normally installed in a horizontal pipeline with the cover over the basket at the top. Cleaning of the strainer is generally simple and no draining is required. Cover flanges for basket strainers are relatively easy to remove and servicing is simple. Replacement of covers is facilitated by some manufacturers through the use of studs, rather than bolts, which help to align the cover during the replacement operations. Hinged covers and screen locking devices can also make servicing easier.
Duplex/Twin Strainers
For applications where continuous operation is required and the line cannot be shutdown for cleanout, duplex or twin (dual) basket strainers can be used. Refer also to Automatic Strainers for continuous service applications. Examples are fuel oil strainers for industrial or marine oil burners, lubricating lines on ships, cooling towers, continuously running chemical operations, and many industrial water intake and service lines. When one basket becomes full, the flow is switched to the other basket. The first basket is removed, cleaned and replaced. For smaller sizes the plug-type or ball-type duplex basket strainer is generally used since it is less costly to construct, and simpler to operate and maintain than other types. It is basically two connected valves with two integral basket wells into which flow can be diverted by rotating the handle.
Twin (dual) basket strainers, two single basket strainers connected in parallel with individual control valves, are also available. It occupies more space than a duplex strainer. However, because of the more circuitous path the liquid must take through a duplex strainer, pressure drop is higher than through the equivalent size single or twin basket strainer.
Temporary (Geometric) Strainers Where cost is of prime importance. U-ideal temporary strainer may be installed between flanges in a pipeline. Variations of temporary strainers include cone, truncated cone and flat geometries. The design considerations with these types of strainers are:
1. They have a lower net open area than basket strainers.
2. The pipeline must be disassembled to inspect, clean or remove these strainers.
3. Structural strength can be difficult to achieve, particularly in larger sizes, and in the case of wire mesh.
While these strainers were once used only temporarily or for startup, frequently they are now left in the line during operation. As with all types of strainers, periodic maintenance must be carried out to ensure efficient operation.
