Testing pressure washers is the proverbial dirty job. We washed concrete and brick pavements, vinyl and cement board siding, aluminum trim and gutters, faux stone, vertical brick, and wood trim. We tackled vinyl fences and outdoor furniture, too. We even very carefully washed some cars (using...
Pressure Testingis required by the ASME BPV Code to test for strength and leaks. There are two methods of pressure tests:hydrostatic pressure testinguses water as a medium, whilepneumatic pressure testinguses air or nitrogen. The latter is more preferred for safety purposes since compressed liquid...

Whenever a valley was judged to be too wide or too deep to be crossed by a bridge, pressure lines known as 'inverted siphons' or simply 'siphons' were employed. These closed conduits transported water across a valley according the principle of communicating vessels. About 80 classical siphon...
Hydrostatic testingis performed by filling the piping system with water to the specified test pressure. The test pressure is usually 1.25 to 1.5 times the design pressure. The piping being tested is isolated and filled with water to the test pressure. All joints, both welded and mechanical, are...
Pressure Cycle-, Burst- and Leak Testing The test rig has two chambers in which up to ten DUTs can be tested at an ambient temperature of -60°C up to 180°C simultaneously. 3 separate fluid circuits allow Glycol (coolant), oil, and water for example to be used as test fluids in on...
Hydrostatic testing is performed to determine if a house or building a sub-slab sewer system contains leaking piping. Test plugs are inserted into existing cleanouts to block and fill the 50+-year-old cast iron sewer system with water. The water is observed in an exposed toilet drain – a...
The flow produced by the nozzle must be qualified experimentally before it is used for testing models. The most convenient method is to use a Pitot probe to obtain the radial distributions of flow Mach number in different sections between the nozzle outlet plane and the diffuser inlet plane. A...
Hydrostatic testing is the primary method used to test for leaks and assess the structural integrity of meter skids, compressed gas cylinders, boilers, tubing, pipelines and other pressurized vessels. It’s performed by filling the system with water, pressurizing it up to a level greater than ...
