What is the erection and fabrication? And what is the hydro test and RT test (NDT) for pressure part?

Question

Accepted Answer

Erection and fabrication refer to the process of assembling and constructing structural components. Hydro test and RT test are non-destructive tests used to ensure the integrity of pressure parts.

Erection involves the assembly of pre-fabricated components on site to create a structure.
Fabrication involves the construction of components from raw materials.
Hydro test involves filling the pressure part with water and pressurizing it to check for leaks or defects.
RT test (NDT) involves using X-rays or gamma rays to inspect the pressure part for any internal defects.
Both tests are important for ensuring the safety and reliability of pressure parts in industrial settings.
