A little explanation:
it is a tank for sparkling wine,
and the user has to open the hatch frequently,
so a flange with a blind cover and a lot of screws is not user friendly
For tanks according to PED, I use this type of door.
Greeting,
can someone recommend manholes according to the sketch, and to correspond with the ASME code?
Oval, opening inside, max 8bar.
