When, where, why to use nondestructive testing

Just as the applications vary, so do the standards to which the tube or pipe must be manufactured and tested. Like the tubes themselves, the methods for testing can be complex. For example, testing tube or pipe for a high-pressure application is not as clear-cut as it would seem. Any of five standards could apply; it depends on the application.

What is a Hydrostatic Test? - Definition from

During hydrostatic testing, the vessel being investigated is filled with a virtually incompressible liquid (often oil or water) and subjected to a precise test pressure. The pressure supply valve is shut off and observations are made to see whether pressure is maintained or there is a pressure loss.

Diverter-Tee Q&A - Heating Help

2014-6-18 · When you first start the system, the water in the radiators is cooler and heavier than the water that's circulating through the main. If trapped air is slowing the flow through the down-fed radiators, the water in the radiators won't have a chance to heat and become more buoyant. If you raise the water temperature, you aggravate the situation.
