Y-type filter
Thread Content
Y-type filters are generally used in horizontal pipelines, but they can also be used in vertical pipelines. I found in some information that when used in vertical pipelines with the fluid flowing from bottom to top, a backflow type should be chosen. I would like to know what is meant by the backflow type of Y-type filter Is the filter inclined downward during installation? What is the relationship between the reinforcement plate of the filter’s internal structure and the filter mesh? Will this reduce the filtering area? Or if anyone has such drawings, please introduce them. Thank you very much
T-type filters come in counter-current types; for selecting such filters, one can refer to SH/T3411-1999 or GB/T14382-2008, which provide detailed information. The original poster seems to be in the design field
Well, thank you for your reply. Why did the person upstairs make such a guess?
The Y-type filter (water filter) belongs to the series of coarse pipeline filters; it can also be used for filtering large particles in gases or other media. Installed in pipelines, it removes larger solid impurities from the fluid, enabling machinery and equipment (including compressors, pumps, etc.) as well as instruments to function properly, thus ensuring a stable processing process and safe production. The Y-type filters (water filters) produced by our company can be customized to meet specific customer requirements (special pressure, special diameter). Y-type filters (water filters) have advantages such as simple construction, easy installation and cleaning, and a large capacity to hold dirt.
The installation methods for forward-flow and reverse-flow filters are different: the forward-flow filter is located inside the cylinder, while the reverse-flow filter is outside it; its performance is inferior to that of the forward-flow filter, and the filter element is prone to being washed away. PS: The original poster said they found this information in some “documents,” and I just saw the same content as well. My first thought was that it might be in Volume 1 of the Manual for the Installation Design of Process Piping in Petrochemical Plants (the so-called red book), but when I checked it, it wasn’t there :L I started to doubt my memory, so I went through all the sections related to filters in the standard manuals I had recently read. It turns out that the document the original poster referred to was Page 15 of SH3012-2000, the General Rules for the Design of Petrochemical Pipelines. It seems I really am getting old :(
I also “want to know what a backflow type of Y-filter is?” ”
