Sealing design for maintenance access openings in pressure-containing equipment

2021-08-04View Original

Thread Content

There is now a ventilation unit with a cubic structure and a fully welded construction. Considerations have been given to installation and maintenance; a maintenance access opening of 600*2000 dimensions has been provided, and this opening is planned to be secured using bolts. The pressure difference between the inside and outside of the equipment is 3000 Pa, and it is necessary to ensure no air leakage. What methods can be used to determine the specifications, quantity, or distribution of bolts? Are there any better structural designs that can meet the requirements for installation and maintenance? Thank you!
