Non-Destructive Testing Methods: Radiographic testing (RT):
Radiographic testing (radiography) is used to detect discontinuities such as porosity, cracks and inclusions in materials or welds. It is performed by placing film or a digital detector on one side of…
SUPPLEMENTAL PROCESSING EQUIPMENT – “MANWAY COVERS” – #METALMARKETUPDATE – NOVEMBER 2021.
Pressure vessels, tanks, large specialty heat exchangers, and other similar equipment generally require large openings for personnel entry (for inspection, cleaning, maintenance, or repairs) or even for certain process additions.…
Non-Destructive Testing Methods: Internal Rotary Inspection System (IRIS)
Similar to eddy current testing, this test method uses an internal probe to inspect heat exchangertubes. But unlike eddy current, ultrasonic inspection is the basis of the method. The IRIS…
Non-Destructive Testing Methods: Helium Leak Test
A helium leak test can be used to find through-wall leaks in pressure equipment and welds. A vessel or exchanger is first filled with 5-10 psi of helium and sealed.…
SUPPLEMENTAL PROCESSING EQUIPMENT – Pressure / Vacuum Relief Devices – #METALMARKETUPDATE – September ’21
Every piece of equipment in a process system should be carefully considered and specified. Arguably the most important safety-related process equipment is the over-pressure control devices. This is considered the…
