Gas Types Available
• Oxidizer/Inert Gases
• Inert Gases (with limited Oxygen 500 PSI or less)
• Flammable/Inert Gases
(Flammable gases as defined by CFR-49. Gases that pose a
hazard of ignition when combined with an oxidizer)
• Reactive/Corrosive and Inert Gases
(For gases that may react due to other components
due to thier acidity or alkalinity)
Our Manual Gravimetric Fill Systems are not intended or designed for blending flammable and oxidizer gases together. These gases MUST be kept separate from any one Manual Gravimetric Fill System otherwise there is a potential for a flash or explosion. The concern is having residual hydrocarbons on valve seats and then having high-pressure oxygen passing through those valves.
Who is Precision Specialty Gas Products?
Precision Specialty Gas Products, a subsidiary of Weldcoa, is a one stop shop for the highest quality equipment and services for the production of specialty gases, allowing distributors to implement, upgrade, or add new capabilities. Precision can help you prepare a budget, design a facility, manufacture the equipment, install the fill systems, train your people and support your business long term with proper documentation and validation of your equipment. We are proud to say all of our specialty gas equipment is engineered, designed, programmed, fabricated, wired, assembled and thoroughly tested at our Aurora, Illinois USA facility.
Our Manual Gravimetric Fill Systems for specialty gas is designed to produce mixtures, (from up to 17 source gases) from percent down to ppb concentrations. Weldcoa provides a long list of technical options ensuring tha your system is customized to meet your specialy gas filling needs. Each unit is fully assembled, pre-engineered, oxygen cleaned and tested before it is delivered, making sure there are no leaks in the common piping. Installation is quick and easy.
All process piping has been hydrostatically tested to 5250 PSIG to ensure quaility and safety
Self-contained cabinet aids in reducing environmental influences to scale
A digital vacuum compond gauge, digital high pressure gauge and digital micron meter are all included for accurate readings
Relief valves are installed for over pressure protection during the fill process
All components are orbital welded and mostly VCR connections. (Oxidizer/Inert model has monel tubing with compression fittings)
All piping components manufactured by Weldcoa have been cleaned for oxygen service per: PSGP Oxygen Cleaning Procedure #PSMB-O2 CLEAN
All GasFlow manual valves and check valves have been cleaned by GasFlow per CGA G4.1-2009 (practive for cleaning methods and cleanliness levels for material and equipment used in oxygen-enriched enviornments)
The entire manifold assembly, including the leads, are 100% hydrostatically pressure tested to 1.5 times the MAWP, 100% nitrogen leak tested, 100% oxygen cleaned, dried, bagged to the highest safety standards.
All Weldcoa Systems are fully built 100% at Weldcoa. The entire manifold assembly, including the leads, are 100% hydrostatically pressure tested to 1.5 times the MAWP, 100% nitrogen leak tested, 100% oxygen cleaned, dried, bagged to the highest safety standards. Weldcoa guarantees all of our structures to be free of manufacturing defects for life.
