common defects of boiler pressure vessels

Air Receiver Tank Care Guide, Sizing, Safety and Storage

Pressure vessels must be built to withstand high internal pressures over a long period of time. Over time, corrosion, stress and fatigue can make tank failure more likely. The most common causes of air receiver failure are: Faulty design/use of non-code tanks. Operation above maximum allowable working pressure (over-pressurization).

Magnetic Particle Testing (MPT) | Inspectioneering

Magnetic Particle Testing (MPT), also referred to as Magnetic Particle Inspection, is a nondestructive examination (NDE) technique used to detect surface and slightly subsurface flaws in most ferromagnetic materials such as iron, nickel, and cobalt, and some of their alloys. Because it does not necessitate the degree of surface preparation required by other nondestructive test methods

What is a Gauge Pressure? - Definition from Corrosionpedia

Aug 07, 2014 · The atmospheric pressure adds to the pressure of any fluid that is not enclosed. Gauge pressure is the additional pressure in any system relative to the atmospheric pressure, and is equal to the difference between the absolute and atmospheric pressure while also being zero-referenced against the ambient air pressure.

NDT (Non-Destructive Testing): What It Is, Common Methods

While NDT methods are typically associated with industrial use cases, like inspecting weak points in a boiler used at an oil refinery, uses in medicine are actually some of the most common. For example, an expecting mother getting an ultrasound to check on the health of her baby would be considered an NDT use case, as would getting an X-ray or

Hydrostatic test - Wikipedia

A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test pressure.
