Hydrostatic Tube and Pipe Test Equipment AIRMO designs and manufactures hydrostatic testers ranging from fully automatic tubing mill applications to smaller operator assisted manual systems. The newest AIRMO high-pressure burst test system is an effective approach in analyzing stress and strain in real-time. It provides simple, safe, and efficient hydrostatic testing and bursting of tubes. The burst bench enclosed in a chamber is connected with a pump control system with high-pressure hoses attached to quick disconnect couplers. The burst bench/chamber is equipped with a slide-rail system for the hydrotest heads, which allows for quick attachment to the test tube. The AIRMO hydrotest heads are designed for a broad variety of diameters, 3/4" to 6" OD and pressures to 20,000 psi. Higher pressures are available upon request. With the ease of use in the test cycle, the operator requirements are to place the tube in the burst chamber, select maximum pressure and rate of expansion, start the test and finally remove when the test is complete. The system allows the ability to pre-fill a tube very quickly, resulting in very short cycle time from connection to test completion. A two-minute cycle is normal. A circular sensor array is placed around the test tube. It transmits dimensional changes, via high-speed data acquisition to the PC: sensor distance readings, systems pressure, and time. Up to sixteen sensors are available based on the tube's size. The precision level for a diameter measurement is +/-.003". With data collection retrievable, you can now achieve calculations for: "k" values, "n" values, region of material instability, burst pressure and ultimate deformation. All AIRMO hydrostatic testers place the tube in tension while under pressure, not compression. This allows the users of these machines to operate in a safe environment while minimizing clamping hardware. AIRMO provides state of the art PLC consoles. These operator stations with their powerful PLCs can be interfaced with various levels of plant communications. This feature yields a truly, fully integrated plant tester. The test head technology pioneered by AIRMO assures a head package that is the best in test. These units are pressure compensated providing increasing grip as pressure increases. This guarantees the test heads will maintain grip integrity at the most demanding pressures. Fully automatic or manual Pressures to 30,000 psi Diameter range 1/8 to 6 (standard or metric) Quick modular change tooling Fast cycle times Digital displays or panel view CRT Tube handling options AIRMO testers are manufactured for the rough rigorous conditions for todays modern tube and pipe mills. These systems are designed to the highest quality standards and are offered from manual operation to fully automated single or multi-tube applications. These mill integrated units or stand-alone machines can be run operator free assuring maximum efficiency.
