DOT’s New Rule - Safer Transportation Without PRD

A new ruling saying pressure relief devices (PRDs) are no longer compulsory on hydrogen tube trailers with cylinders longer than 12 feet is being hailed as greatly improving the safe transportation of the gas in the US and Canada. The Pipeline and Hazardous Materials Safety Admin...

Anti Rotation Pinning of Pressure Vessels

Tube pinning is a process FIBA uses to prevent tubes from rotating within their assemblies. The majority of tubes used in tube trailers, ISO containers, and ground storage assemblies are mounted in bulkheads. Tubes are held in the bulkheads by external threads machined onto the t...

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...

Oxygen Cleaning Services

Risks Associated with Oxygen-Enriched Environments Cleaning for oxygen service, or oxygen cleaning, is the process of contaminant removal from components to be used in oxygen service. An enriched oxygen environment (defined by OSHA as greater than 23.5% oxygen by volume) signif...

Fill Pressure in Hydrogen Service

10% Overfill by SP FIBA manufactures 3AA ton containers and 3AAX tubes. By DOT definition, both are cylinders. Both containers are suitable for hydrogen gas service. But, rather than being used for hydrogen, the 3AA tons are generally used for liquefied gases such as chlorine, HC...
