Vacuum Chambers

There are three important elements required for the design and manufacture of a vacuum vessel:

· Experience
· Welding
· Leak Detection

Ability Engineering Technology has all three.

Experience

Ability Engineering Technology has been involved in the design and manufacture of vacuum vessels and vacuum systems for 12 years. The experience of the principles includes over 30 years experience in the design of vacuum vessels and systems.

Ability manufactures chambers for high and ultra high vacuum vessels including he design and custom manufacture of wire seal flanges up to 68" in diameter. In addition to the design and manufacture of vacuum vessels Ability has in house machining of all components used in the manufacture of these vessels. All welders are ASME code certified and all materials can be traced to their source in accordance with ASME Code requirements.

The range of shapes and sizes of vessels designed include torroidal shaped vessels for service in a plasma fusion experiment and kidney shaped vessels used for bending magnets at a University Cyclotron. The range of materials we have used include:

· Stainless Steel
· Aluminum
· Inconel
· Titanium

Welding Technology

Over 90% of the welding performed at Ability is vacuum related in some way. We build complex cryogenic equipment containing process piping housed within a vacuum vessel. This requires that each weld be leak checked at least twice. Each welder is trained and tested for both weld integrity as required by ASME Code and our high requirement for quality, leak free welds. A continuing flow of vacuum related welding projects keeps our welders fine tuned to this requirement. Our welding equipment is "State of the Art" Pulsed Tig. All of our welders are ASME Code certified.

Leak Detection

Ability has two late model Helium Mass Spectrometer Leak Detectors capable of detecting leaks as small as 1 X 10-10 std cc's/sec. We have pumping stations including a roots blower, cold trapped diffusion pump systems as well as a turbo and cryopump. All of our vacuum equipment is manned by experienced technicians.
Review our web page for examples of the many vessels we have built. One of our most recent vessels was 60" in diameter x 12' long a we were able to pump it down to 5 x 10-9 torr in 3 weeks with no bakeout and using only a single 500 1/sec turbo.
