What are pipe basket strainers, y strainers, conical strainers used for.

Hello everyone and welcome to another exciting and educational episode of IV University. Where you can get your PVF Degree for free. Today's episode we talk about strainers, and I promise you that this episode will make you think, It will make you use your head, and your mind, and your brain… also a special guest renown painter Bob Ross will teach us how to make sure our PVF is always looking great.
But first lets talk about strainers.
A strainer is defined by its purpose to remove unwanted large particles from a liquid suspension, usually to protect some sort of downstream equipment, such as a pump or a more delicate filter, from the damage that these rogue particles might cause.
The three strainers most commonly used in the industrial PVF world are the close up’s . the y strainer, the basket strainer, and the conical strainer or more frequently called “cone” strainer or “witches hat”. In fact, a quick aside, just like in harry potter movies these “witches hat” can double as a sorting hat to tell you which house you belong to.
So lets talk about the y-strainer… Y-Strainers are the most used devices for mechanically removing unwanted solids from liquid, gas or steam lines by means of a perforated or wire mesh straining element. Video They are used in pipelines to protect pumps, meters, control valves, steam traps, regulators and other process equipment. They do this by utilizing a perforated metal, mesh or wedge wire straining element. ...
You must pay attention to the orientation of the chamber which collects debris and the drain (blow-down) connection of the Y Strainer.
To provide for easier maintenance, the Y-Strainer should be located where the drain plug can be removed. Additionally, ensure the drain or blow-off is located at the lowest position when installed. If installed in the vertical position, the wye side of the strainer must be pointing downward.
Lets talk Basket strainers, these strainers feature a top removal of the screen. The screen is the form of the basket with a lifting handle, so that all particulate captured and retained by the screen can easily be removed. In most cases, Basket strainers used mostly for smaller valves.
The third main type of strainer is the conical strainer. This strainer is a temporary strainer for any fluids application. For trapping foreign particles in the pipe line to be used as temporary strainers during start up and trail runs.
So what did we learn today about strainers? Lets review… a strainer is used to protect other downstream equipment from damage by rogue junk. A filter is employed to separate particles from the fluid.
The 3 main types of strainers used in the industrial PVF world are,video the y strainer which is the most used device for mechanically removing unwanted solids from liquid, gas or steam lines by means of a perforated or wire mesh straining element. IV carries these in Bronze/WCB/Cast iron & stainless.
The Basket strainers, these strainers feature a top removal of the screen. The screen is the form of the basket with a lifting handle, so that all particulate captured and retained by the screen can easily be removed. Picture IV carries these in cast iron and wcb with clamp covers for easy access or bolt covers for long term lock down.
The conical strainer which strainer is a temporary strainer for any fluid applications. This is used trapping foreign particles in the pipeline to be used as temporary strainers during start up and trail runs.
Bonus did you know mesh size varies on all these strainers, and these strainers are used quite often for sediment, but mostly for equipment, welding rods, gloves, hard hats, etc. that are mishandled by those working the pipeline upstream.
so I hear a lot from viewer mail and people stopping me on the streets saying Professor Jim, video why does all the PVF you show in these segments look so good. Well its because we take great care of course, but also if there is a chip in the paint and if they get a little sloppy looking we have our warehouse watch a video on helping our PVF look it’s best,camera which leads me to introduce a the video we show them entitled “the joy of painting PVF” with Bob Ross.
So there you have it, you now know everything about Industrial Strainers, and how we keep them looking so good. Have a great day everybody.

Good info and cracked me up the whole way through xD

Respected sir
I am working in chemical plant and we use cone strainer in a spacer and they call it I typw strainer... Can it be use internationaly

Great video. What usually gives more pressure loss, a conical strainer or a basket strainer?

[@ivuniversity4930]

Thanks Lewis, Y - Strainer is the lower pressure drop.

[@ivuniversity4930]

So many factors of the installation come into play when figuring pressure loss. Both cone, and baskets are offered in different open area ratios. Commonly 100%, 150%, 200%, and 300% open areas. This will determine the design length of the temporary strainers. They Both have very similar if not the same Cv valves for the respective sizes also. So one will not really give you more of a pressure loss than another. The real differences between the two is the length.
Example; A 200% OAR cone strainer (witches hat), will be much longer than the basket type (pilgrim’s hat) at 200% OAR. This can be a space saver in the long run.
10in 300% O.A.R. Cone strainer (witches hat) = 41 inches long
10in 300% O.A.R. Basket strainer (Pilgrim’s hat)= 26 inches long
Hope this helps!

@@ivuniversity4930 Interesting, thank you! OAR is a useful keyword.
But from my understanding basket strainers have the filtration element perpendicular to the flow, and come as a large stand-alone unit shaped like a T. Therefore making the "pilgrim's hat" longer doesn't really make much difference; you're extending the strainer into a region of no flow? Whereas a temporary cone strainer is in-line with the flow and hence making it longer does have the improvement in pressure drop?
Or are you comparing two temporary in-line strainers, a cone (witches hat) and a cone with a flat end (pilgrim's hat?). Because currently I am trying to find a small strainer with low pressure-drop and hence wondering whether I should be looking towards a temporary in-line strainer or something like a Y strainer.

@@ivuniversity4930 why you call them temporary strainers?
