Automotive
Automotive plants use pressure vessels on both sides of the same line: feeding sealants and adhesives to dispensing heads, and leak-testing the assemblies that come off it. Both jobs reward a vessel that holds its pressure without being watched.
On the line
Feeding a line
The question we get asked most often about production feeds, and the answer depends on the heads rather than the fluid.
Specifying for a line
There are no automotive case studies published yet; what is here comes from the specification questions these installations start with.
| Duty | Feeding a dispensing line, or testing what comes off it — the two lead to different vessels |
|---|---|
| Fluid | Sealant, adhesive or test medium: viscosity and abrasiveness decide the wetted parts |

Which side of the line the vessel sits on decides almost everything else.

The assembly is sealed inside the vessel and the chamber is pressurised to represent the conditions it must survive. With a transparent body the escaping air is visible as a stream of bubbles, so the test identifies where the leak is rather than only that there is one.
Yes, through a manifold, and it is the usual arrangement when the heads dispense the same material — one pressure to regulate and one vessel to refill. Where the heads run different materials, or a station has to be stopped on its own, a vessel per head is the better answer.
IP67 is immersion to one metre for thirty minutes; IP68 is deeper, with the depth agreed between manufacturer and customer. Both are applied as pressure in the chamber, so the ceiling is the vessel's rating rather than the rating you are claiming — tell us the depth and we will confirm it.
