BOC supplies customers with liquid argon gas systems to create the appropriate inert atmospheres for Hot Isostatic Pressing (HIP) processes.
The HIP process is carried out inside a pressure containment vessel within which the work pieces undergo appropriate thermal cycling under high isostatic pressures, usually in a gaseous argon atmosphere.
High purity argon is used to provide the inert atmosphere necessary to prevent any chemical reactions adversely affecting the materials being treated.
Under the HIP process conditions of high temperature and pressure, micro porosity and voids in cast products are reduced or eliminated by plastic deformation, creep and diffusion bonding.
Hot Isostatic Pressing is used to improve and optimise the mechanical properties and fatigue performance of manufactured parts and to extend the service life and reliability of critical high performance components and assemblies.
Typical HIP applications include gas turbine components, automotive engine parts, turbo charger wheels, aerospace structural parts, medical implants, prosthetics, near net shapes and general engineering parts.
BOC’s product supply, engineering capabilities and experience interacts with customers operating HIP processes, in the following areas:
- Design, provision and installation of argon gas supply systems.
- Provision and commissioning of controlled atmosphere technology and control equipment to support HIP processes.
- OnStream gas system design and maintenance services.
- Gas safety equipment, safety checks and training.
