Hydrostatic Test Rig Design Drawingsonly at www.scubaengineer.com !
The worlds major cylinder hydrostatic test equipment including fully automated manufacturers are:- Galiso (USA) , Hydro-test (USA) Smaller manufacturers of manual systems are Birchley Products (UK) birchley_products_prices1_2009.pdf birchley_products_prices2_2009.pdf An example of the air powered Low volume high pressure pumps used in these test systems is:- trojan_air powered high pressure hydraulic pump.pdf The hydrostatic test system represents the largest capital equipment expenditure of the fledging test center. Expensive fully automated systems capable of testing a hundred cylinders per day and costing $100,000 + are not required by everyone. However, a manual system capable of hydro-testing a few cylinders a day can be locally manufactured relatively easily by any workshop with basic engineering and welding facilities for a few thousand dollars (including hydraulic pump, hoses and gauges) The American Compressed Gas Association standard CGA C-1 "Methods for Hydrostatic Testing of Compressed Gas Cylinders" contains a full description of the design of suitable system contains a full description of the system requirements. Anyone considering building a hydrotest system should obtain a copy of this standard first. Below is presented the working drawings of a hand built hydrostatic rig design, that with traceably calibrated gauges, correct installation, trained operators, up to date technical data can achieve measurement accuracy sufficient to meet International standards (CGA,BS/EN/CE) for testing compressed gas cylinders.
