Service Checklist for Hot Isostatic Presses

Without sufficient preventive maintenance, the failure rate of electrical, hydraulic, and mechanical systems increases substantially with each year of production. A good PM program checks and replaces components to maximize uptime.

Check the emergency cooling pump

Adequate cooling is critical for the life-time of the cylinder. Therefore it’s important to keep the emergency cooling pump in working order at all times.

Length and diameter measuring of the frame and cylinder

The pre-stressed pressure vessel is the core of any Quintus press. By measuring the frame and cylinder it’s verified that the vessel components are still intact and safe for further use. The measurement of frame and cylinder is analyzed by a Quintus specialist.

Alignment of the press

When installed, the Quintus press is aligned properly but with time foundations may set or change in other ways.

Crack inspection of upper and lower closure

In the case cracks would appear in the closure they can often be polished off.

However, should they occur, it’s critical that they are discovered as soon as possible.

Removal of the thermocouple feed-through, replacement of TCs and sealing

With time and cycles the feed-throughs may start to leak. In order to avoid this, preventive changes should be made on a regular basis
