Dear kjafari,
As I said, all the info is in the Koch site;- however yes, the Breech Lock type of closure can be attached to a shell and tube exchanger and from the Koch site, you can see that they build this type of exchanger for high pressure and high temperature used in hydrocracking processes. Typical refinery applications are pictured over the website. They fabricate (and sell) horizontal and vertical exchangers with the Breech-Lock closures, in many configurations including shell and tube exchangers. Please follow the links leading to Koch Heat Transfer Company's site or please type in Google the name "Koch Heat Transfer Company".
Best of luck,
