Acceptable porosity severity level for sealing surfaces in compressors
Hello fellow engineers and machine heads,
I am presently working on defining the porosity severity level for sealing surfaces(aluminum) in screw compressors. We have received few reclamations for a component(air regulator) as there was a leak in the sealing. The major cause for this was the pores in the component. We already have quality requirements (ISO 10049) to meet the porosity level for the casting models. But how do I realize how much porosity severity level is needed to achieve the safe functionality of the component without any leak? Are there any other European standards(EN/ISO/DIN) to determine the quality of the pores after machining? Any knowledge on this would be appreciated.
Thanks in advance
Regards,
Srimanish Reddy
