Purpose: Many new discoveries of oil and gas field are in high pressure -high temperature (HPHT) environment. The development of such fields requires appropriate selection of materials that are able to withstand not just the service loads but also corrosive production fluids in the HPHT environment. There is a need for Research Implications/limitations: The maximum design pressure of 15 MPa is more than sufficient for high pressure corrosion studies in aqueous solution where partial pressure of
more » ... the dissolved gas is one of the main controlling parameters. However, the design pressure is only suitable for corrosion studies in seawater environment up to 1500 m of water depth. Originality: A new design of autoclave together with all the necessary piping, assembly and control system is proposed for high pressure -high temperature corrosion studies. The autoclave can be used as standalone or integrated with mechanical testing machine and thus enables corrosion studies under a wide range of loading.
