Requirements for the installation of inspection holes
Thread Content
Is it necessary to provide inspection holes in the pressure vessel for holding steam (diameter DN800)?
The corrosion caused by water vapor (erosion, cavitation, etc.) is quite significant; therefore, inspection holes should be provided.
If the process pipe openings meet the inspection requirements, it is also possible to avoid setting up something separate
If the process pipe ends of DN 80 and above can be used as inspection ports, there is no need to install separate ones
Thank you for your reply. If there is no process pipe outlet that can be used as a inspection port, is it necessary to install an additional inspection port under such circumstances?
The maintenance issues specified in the design documents, as well as equipment inspections, should also be indicated.
