Quick Opening Closure for 5000psi vessel

Quick Opening Closure for 5000psi vessel

Quick Opening Closure for 5000psi vessel

(OP)
We are designing a vertical pressure vessel and are in need of a quick opening closure. This will act like a top removeable head. The vessel has a design pressure of 5000psi. Does anybosy know of a company that manufactures closures at this pressure? The closest that I've found is 4500psi.

RE: Quick Opening Closure for 5000psi vessel

Look at the designs of autoclaves and gun breaches. They use plugs or rings with lugs that lock the vessel closed with a fraction of a turn. On small vessels a V-grooved clamp ring that is spit in half is a simple design. Two bolts can hold the ring together.

RE: Quick Opening Closure for 5000psi vessel

Contact the company that makes them. If they can design and build a 4500 psi unit, I'll bet they can design and build a 5000 psi unit.

You don't say so, but if your vessel is a Code vessel, there are a number of specific requirements for Q.O. closures and the means to meet them is not necessarily obvious.

Regards,

Mike

Bandlock 2 closures are rated up to 6000 psi.

RE: Quick Opening Closure for 5000psi vessel

If your closure is at a low enough temperature that you can get by with elastomeric o-rings, you have a shot at this.  Depending on size, there are quite a few options.

Temperatures higher than o-rings will tolerate?  Unless you can tolerate a lot of leakage, "quick opening" will be a matter of opinion or will come with a lot of cost and complexity.
