determining pipe penetration type
determining pipe penetration type
(OP)
Hi Engineers,
I would like to know how we determine the pipe penetration type (between doubler and sleeve) on bulkhead penetration
when should we use doubler or sleeve? is there any factor such as pipe pressure or plate thickness that affect the determination? please somebody help.
many thanks,

You got to give more details of the installation.
Our questions here:
Purpose, pressure, temperature, material?
Do You mean: making a branch on a plate?
No pipespecs over there?
Greetings
RE: determining pipe penetration type
In my understanding, a sleeved bulkhead penetration would allow leakage between compartments and may or may not be acceptable in some areas.
The type of piping penetration depends on the compartment requirements as well as the engineering requirements of the piping system ( most importantly, the piping system temperature)
RE: determining pipe penetration type
this is for carbon steel pipe passing through watertight bulkhead.
based on factors such as temperature and pressure, how do we choose between doubler plate and sleeve for watertight penetration? I just want to know the comparison based on those factors for doubler plate and sleeve penetration
I'm confused by a design, let say 'bilge suction lines' 40 Bar, 35 degree C, ASTM B 36.10, there are some bilge suction lines passing through different compartments (penetrating watertight bulkhead), these lines go to bilge suction manifold. some of the lines penetrate watertight bulkhead using doubler plate while some others using sleeve. I have checked the watertight bulkhead, there is no limitation, all pipes have the same space (no stiffeners to avoid) it's just a wide space of the plate to penetrate, passing through the same compartments, but why it uses different pipe penetration (doubler and sleeve)?
many thanks,

plagueland says "this is for carbon steel pipe passing through watertight bulkhead"
If axial movement is possible between pipe and sleeve, as you suggest, then surely the bulkhead will not be watertight!!!
