Applications

High Pressure Pasteurization

Advanced Material Densification

Sheet Metal Forming

Avure Confidential 20129

Advanced Material Densification• Hot Isostatic Press

15,000 to 30,000 psiArgon gas medium4000 °FID=0.5 to 7.9 ft

• Cold Isostatic Press15,000 to 58,000 psiWater/Oil emulsion mediumAmbient temperatureID=1.3 to 8.2 ft, up to 23 ft long internally

Avure Confidential 201210

Hot Isostatic Press

• A combination of temperature and pressure heal internal voids in metal and ceramic materials to substantially improve strength

Avure Confidential 201211

Cold Isostatic Press

• Pressing encapsulated metal and ceramic powder to achieve high density, high green strength and consistent properties before subsequent sintering

Metal filters Nozzles for continuous casting and stopper rods

Avure Confidential 201212

Food Press

• Food Press58,000 to 87,000 psiWater mediumAmbient temperatureID=0.6 to 1.6 ft

Food Press

Avure Confidential 201213

• Pre-packed food is exposed to high pressure by water media

• No mechanical damage is caused to the food as isostatic pressure, equal pressure from all sides, is used

• Microbiological reduction without using destructive heat

• Increased shelf life without the use of chemicals or preservatives

• Tender meat, shell easier to remove from oysters• Press cycle 5 – 10 min

Inspection of QUINTUS® Pressure Vessel

Avure Confidential 201218

The in service inspection of QUINTUS® pressure vessels can be divided into 2 groups

• Maintenance and inspection for safe and reliable operation

• Inspections and measurements for safe operation and check of wire wound components

Maintenance

Avure Confidential 201219

Maintenance and inspections for safe and reliable operation includes

• Visual inspection of- Vessel and closure, High temperature furnace- Hydraulic system, Gas system- Electrical equipment, Cooling water system

• Water and oil check, oil change, filter cleaning, leakage check

• Lubrication of high pressure seals• Back-up battery change

Argon Hazards

Avure Confidential 201225

• A heavy gasIt can accumulate in low places

• It is not poisonous• Dangerous, it displaces air and its

oxygen in a way our senses cannot detect

• Unconsciousness occurs in seconds when inhaled

Argon Hazards

Avure Confidential 201226

Oxygen concentrations• 21% Normal air• 17% Normal exhalation• 12% Stupidity• 8% Unconsciousness• 6% Heart and Lungs stops

working

Always carry an oxygen detector!
