How to install temporary strainer (cone type)
How to install temporary strainer (cone type)
(OP)
Hi!
I know that temporary strainer (cone type) can be installed 2 direction as follow:
1 fluid flow from outside of strainer to inside.
2 fluid flow from inside of strainer to outside.
Can you please tell me how we decide to install temporary strainer?
Gas flow is difference from fluid flow?
Thanks and regards,
Big.

Contrary to what some engineers think, a cone strainer is designed to do its work with the tip of the cone FACING the direction of flow (facing upstream). In other words, this strainer is designed to collect debris and trash around the outer edges of the cone because this is a mechanically stronger orientation. If you place the cone with the tip facing downstream, debris will collect in the tip and rip the cone apart due to the heavier strain on the mesh and it's construction. This type of strainer should use a wire re-inforcement to ensure its mechanical stability.
My Mechanical Engineering mentor, Alf Newton, taught me this and proved it out in the field when I entered my first plant engineering job 44 ago. Ever since that time, that's the only way that I have ever installed cone strainers during startups and it's the way I have taught all engineers that I have mentored or supervised since then. I'll bet his logic and design still work.
I don't know how ya'll decide to install a temporary strainer. I do it routinely when starting up new or rebuilt equipment.
Gas flow is fluid flow. There is no difference.

11000, if you contact the manufacturer to get their installation guidelines, I would like to know what they say.

By the way, we refer to this conical style of start-up screen as a "witch's hat".

http://www.weamco.com/cone.htm is an informative web site showing four different conical strainers that Weamco manufactures. Two of the four are bidirectional, one shows flow opposite of the pointed end of the cone, and the last show flow in the direction of the pointed end of the cone. So the bottom line is that you should install the conical strainer per the manufacturer’s instruction.
