What are the requirements for the mesh size of the temporary filter?
Thread Content
The installation is about to go into operation, and it’s necessary to purchase some temporary filters, but the standards and specifications are not known. The main media used in this installation include water, natural gas, MDEA, steam, etc.!
No, it’s a natural gas desulfurization and sulfur recovery unit

For the pump inlets for amine solutions and wastewater, the standard filters used in design are typically 40 mesh per inch; however, those chosen in our workshop sometimes have a mesh count of 20 mesh per inch. Here are some terms from the standards: 1. HG/T 20597.22-95: For the filter screens used in temporary filters, half of them should be filter screens with 100 pores/cm2. ——Equivalent to 25 mesh per inch. 2. HGJ 532-91: This standard specifies that filters shall use a stainless steel wire mesh with 30 mesh per inch as the standard. 3. SH/T 3411-1999: When the pump has no special requirements regarding the medium to be transported, a 30-mesh filter screen can be used.
