Pressure Vessels for the Defence Sector
SCOPE:
The manufacture and testing of pressure vessels for the containment of hazardous materials as part of an infrastructure dismantling programme for the UK defence sector.
THE CHALLENGE:
A historical design requiring to be updated for modern manufacturing standards.
THE SOLUTION:
Our engineers developed a successful solution by identifying alternative gaskets and materials and validating these under rigorous hydro-testing conditions. The approved design solution can be utilised for future similar applications.
RELEVANT TECHNICAL DETAILS:
- 6mm 316 grade stainless steel inner can with a dished end encased within an 8mm thick S355 grade outer mild steel can with a 20mm thick base.
- Concrete casing between each canister.
- All full penetrant butt welds were 100% radiography and DPI/MPI inspected.
- All butt welds 100% radiography and DPI/MPI inspection.
- Each stainless steel canister was hydrostatically tested to 14 bar.
- Manufactured to PD5500 Cat 2.
