UHV Chambers
Product Details:
These are Custom Built Chambers used for Ultra High Vacuum Applications .The UHV chamber is made of SS AISI 304 material which consists of no. of ports, for various application made with conflat flange/ NEC flanges and covered with matching flanges.
All welded components as well as the total chamber is leak tested by using Helium Mass Spectrometer leak Detector to individual leak rate better than 1x10-9 std cc/sec. The assembly will be evacuated to high vac before despatched . All components are machined strictly as per UHV international specifications. The chamber is buffed and polished to good finish. All welding are done by TIG argon arc welding internally and filler material is avoided as far as possible. The design of the chambers follows pressure vessel design as per ASME code Sec. VIII Div. I and the fabrication follows ASME code Sec. VIII. The chambers are fabricated by TIG Argon Arc welding following ASME Code Sec.IX. All welding joints are tested and radiograph as per ASME code and leak tested by Helium Mass Spectrometer leak detector better than 1x10-9 std cc/sec/ and finally buffed and polished to good finish as per good vacuum practice and to provide 0.1 micron Ra value finish for all the internal surface. It can be of anysize or shape or contours as per customer`s requirements
