"UNPARALLELED PERFORMANCE AND SAFETY UNDER PRESSURE!"® TestMaster® Model 500 Series Hydrostatic Test Tools ■ Pressures up to 15,000 psi (1,034 bar) ■ 0.25 in. to 3.50 in. OD (6.4 mm to 88.9 mm OD) ■ Collet grip and retractable seal on tube OD ■ Air-piloted clamp and release ■ Pressure-compensated grip DESCRIPTION The 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 pre-clamp and release of collets. The tube seal retracts during tube loading and removal, greatly enhancing seal life. APPLICATION The TestMaster® Model 500 Series Hydrostatic Test Tool is suitable for hydrostatic pressure testing and hydro-expansion on tubes and pipes with standard OD tolerances with working pressures up to 15,000 psi (1,034 bar). This tool conforms to military, nuclear, automotive, and aerospace testing specifications such as API, ASTM, ASME, ISO, DIN, and BS. The pressure compensated design on the Model 500 Tool places the tube or pipe in tension, using internal pressure to increase grip on the tube OD. This design eliminates the need for tube clamping devices along the tube length. The Model 500 Hydrostatic Test Tool grips and seals on the tube OD. One tool size will accommodate multiple wall thicknesses, while maintaining high fill rates. The Model 500 Series Tool comes in standard and metric tube, pipe, and fitting sizes from 0.25 in. to 3.50 in. (6.4 mm to 88.9 mm) in diameter. For tube sizes larger than 3.50 in. (88.9 mm), please contact Airmo for specifications and options. MATERIALS Wetted Parts: Heat-treated, stainless steel TOOL CONFIGURATION Collet Grip: Gripping: Seal: Mounting: Actuation: Air Requirement: On tube OD Pressure-compensated Retractable seal on tube OD Tapped holes in body Air-piloted clamp and release 80 to 100 psi (5.5 to 6.9 bar) Maximum Pressure: Temperature: Services: Tube OD Range: OD Tolerance: OPERATION Connect the Model 500 Tool to the air and fluid lines. Apply air pressure to release port to open collets and retract tube seal. Insert the pipe until it is passes the tube seal. Redirect air pressure to clamp port, and the collets and tube seal will engage with the pipe OD. Apply fluid pressure to desired level, but do not exceed maximum operating pressure. After pressure cycle is complete, release all fluid pressure. Finally, release collets as before to remove pipe.
