Issues with openings in the elliptical heads of heat exchangers
Thread Content
The diameter of the head is 2500; one manhole, 4 temperature measurement ports, and one vent are required. Which standard should be followed? Should it be reinforcement through an opening in the cylinder, or reinforcement through an opening in the flat cover?
Calculate according to the reinforcement for openings in elliptical heads. It can be calculated using SW6, or by hand as well.
It is best not to locate the access opening on the manhole cover; the manhole should be placed in the middle of the head, while the vent should be located at the top of the equipment. If it is necessary to have an opening on the head, then there must be a duct inside the equipment, with the duct’s opening also at the top of the equipment.
Thank you! ! ! What I mean is that when all the aforementioned holes are made in a cover, what are the standards regarding the arrangement of these holes and the distance between them? There are regulations regarding the spacing between 2 or more holes made in the cylinder body as well as regulations for making multiple holes in the flat cover; however, there are no standards for making multiple holes in a cover. .

The openings in oval end caps must comply with the spacing requirements for openings on shells as specified in GB150, and cannot follow the standards for flat covers.
