Autoclave Systems high pressure and high/low temperature test

Autoclave Systems for high pressure and high or low temperature testing are forged pressure vessels with stands, porting, stirrers, holders and controls for exposing metal coupons and specimens to hot, pressurized, corrosive fluids. They serve corrosion laboratories and materials groups running corrosion testing, electrochemical studies, corrosion inhibitor analysis, shear stress analysis and slow strain rate testing. Results guide material selection for sour and high-pressure service.

How it works

The vessel body and lid are machined from solid forgings with no welds or overlays, in 316 stainless steel, Hastelloy C-276, Inconel 625 or titanium. The bolted lid closes on a metallic or PTFE seal ring. Working pressure is up to 103.4 MPa (15,000 psi) and working temperature from -50 to 600 °C (-58 to 1112 °F), with vessel capacities up to 20 liters. Specimens are mounted on the chosen holder, test fluid is charged, and pressure and temperature are held at set point for the exposure period.

Specimen holders include rotating cage, rotating coupon, rotating cylinder electrode, 3 and 4 point bend fixtures and static coupon racks. Water-cooled feed-throughs pass a load train for tensile, slow strain rate or fatigue testing. Porting is configured per project: HIP or NPT connections, isolated feed-throughs, sight glass windows. An in-line or belt drive magnetic stirrer is available. Control is by the Model AC-20 PLC controller with touch screen, by a PC with data acquisition and custom software, or by a multi-system controller for several autoclaves.
