Reactive Metals Fabrication Bay
Cembell has a 15,000 SF facility for the fabrication of high alloy materials. The High Alloy Bay is climate controlled with painted floors and completely segregated from our other fabrication bays. We fabricate Titanium and Zirconium Heat Exchangers, Pressure Vessels, Piping, and Miscellaneous there. The bay contains a 6 ft deep pit to facilitate welding of heat exchanger tube-to-tubesheet joints in the flat.
Cembell has multiple orbital welding machines for reactive metal welding. We utilize these for a variety of applications, including seal welding and strength welding of tube-to-tubesheet joints. We also have GTAW manual welders with years of experience working with Titanium and Zirconium.
FEATURES
HEPA-N-Seal negative pressure safety seal for zero-leak ceiling grid
Temperature / humidity control enclosures
Positive airflow and complete segregation from all contaminants
Negative pressure around all the filters to ensure that no air will leak through the ceiling grid and into the critical clean room space
