Internal Cleanliness of Steel Vessels for High Purity Applications

Many steel pressure vessels are utilized for the global shipment of electronic-grade gases, such as silane, NF3, HCl and N2O, which are used for the manufacturing of semiconductor materials. The purity of this gas is paramount to semiconductor quality because impurities can be de...

UPDATE: Fill Pressure in Hydrogen Service

NOTE: DOT regulatory changes require the March 25, 2013 posting to be updated. SP No Longer Required for 10% Overfill in Hydrogen Service As noted in a prior blog, FIBA manufactures 3AA ton containers and 3AAX tubes. By DOT definition, both are cylinders. Both containers are su...

Composite Gas Trailers

FIBA Technologies is blazing a path to the future with new lightweight compressed gas trailers using aerospace grade carbon fibers and advanced polymers. The result is the ability to reduce fleet sizes by carrying more gas and less steel with high capacity, lightweight compressed...

Cylinder Ultrasonic Examination

DOT pressure vessels (cylinders) require periodic inspections to evaluate the integrity and safety of each vessel. After years in use, it is important that authorized holders of a Requalification Identification Number (RIN) conduct a thorough examination of each vessel. Two non-d...
