Model 500 Series
Hydrostatic Test Tools
Pressures Up to 15,000 psi (1,034 bar)
The patented TestMaster® Model 500 Series Hydrostatic Test Tool allows production speed hydrostatic testing for tube mills and other applications where accurate, rapid testing is needed. The tool design employs an air-operated mechanism for positive preclamp and release of collets. Its tube seal retracts during tube loading and removal, greatly enhancing the seal life. The tool can be used with a variety of services, including water and oil.
The Model 500 Series Tool is suitable for hydrostatic pressure testing up to 15,000 psi (1,034 bar). The Model 500 handles standard and metric tube, pipe, and fittings sizes from 0.25 in. to 3.50 in. OD (6.4 mm to 88.9 mm OD). This tool is suitable for testing according to military, nuclear, automotive, and aerospace specifications such as, API, ASTM, ISO, DIN, and BS.
The pressure compensated design of the Model 500 Tool places the tube or pipe in tension, using internal pressure to grip and seal on the tube OD. This design eliminates tube clamping devices along the tube length. One body size will accommodate multiple wall thicknesses, while maintaining high fill rates.
Normally two Model 500 Tools are used for tube testing. One tool fills the tube, and the other tool plugs the tube until completely filled. For optimal tool performance use with NuQuip® Automatic Air Bleed Valves.
