I have pump suction piping system ( 5 Pumps ) with 16" duplex strainers for effluent water transportation. The line is successfully installed and piping is air blown, hydrotested and getting ready for commissioning. For commissioning what type of strainers is the most preferred. If temporary conical strainers are used, to clean the debris collected strainer spool need to be removed along with bolts and gaskets which is time consuming. So it is suggested to use temporary strainer mesh ( Fabricated to match strainer basket)on duplex strainer. Advantage of using duplex strainers with temporary mesh requires less efforts, since basket can be cleaned by diverting the flow through other chamber of strainer and inactive strainer compartment can be cleaned by removing the basket by opening the quick opening door of the strainer ( Sealing of the basket quick open door is by using O-ring).
Thanks in advance for your expert opinions.
