Supply chain intelligence pressure vessel inspection with clear english inspection report
A Pressure vessels is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.
Pressure vessels can be dangerous, and fatal accidents have occurred in the history of their development and operation. Consequently, pressure vessel design, manufacture, and operation are regulated by engineering authorities backed by legislation. For these reasons, the definition of a pressure vessel varies from country to country.
General ASME Vessel Certification/Stamps
“U” For Manufacture of Pressure vessels (Division 1)
“U2” For Manufacture of Pressure vessels (Division 2)
“PP” For Fabrication & Assembly of Pressure piping.
“S” For Manufacture and Assembly of power Boilers.
“R” The National Board of Boilers Pressure Vessel Inspection Certificate.
2. Design and test method of pressure vessel
Design involves parameters such as maximum safe operating pressure and temperature, safety factor, corrosion allowance and minimum design temperature (for brittle fracture).
Construction is tested using nondestructive testing, such as:
and pressure tests.
Hydrostatic tests use water, but pneumatic tests use air or another gas.
Hydrostatic testing is preferred, because it is a safer method, as much less energy is released if a fracture occurs during the test (water does not rapidly increase its volume when rapid depressurization occurs, unlike gases like air, which fail explosively).
