What is accumulation/ set pressure of PRV, PSV?
With referance to: Pressure Level Relationships chart Accumulation & Overpressure of PRV; When the Pressure Relief Valve (PRV) is active ( open): -% of the excess pressure from the “system MAWP” is called “Accumulation” -% of the pressure beyond the “set pressure” of the PRV is called “Overpressure” PRV – Maximum Set Pressure & Accumulation of the ASME Code; According to ASME Code, Pressure Relief Valve (PRV) must have maximum Set Pressure and Accumulation not higher than the table (% MAWP) which will be divided into Nonfire Case and Fire Case for use in both PRV ( Single PRV) and … Continue reading What is accumulation/ set pressure of PRV, PSV?
Caustic corrosion cracking of Carbon Steel.
Usability of CS in Caustic Soda Service to Prevent SCC; API 571 recommends the use of carbon steel materials with Caustic Soda (NaOH solution) according to the concentration and temperature. To prevent stress corrosion cracking (SCC) Continue reading Caustic corrosion cracking of Carbon Steel.
Flange & Stud bolt inspection
Flanged Joint Inspection – Corroded Stud Bolts; Stud bolt caused by Corrosion will reduce the area where the corrosion occurs, resulting in less cross-sectional area and resulting in reduced ability to withstand the force. Continue reading Flange & Stud bolt inspection

What is Coalescer or coalescence filter?
Coalescer 1; Coalescer is used to separate Emulsion substances such as water and oil (hydrocarbon). By using the unification principle of small liquid droplets into larger droplets as the material flows through the coalescer element. Coalescer 2; The work of Coalescer will have three phases starting from filtering out the impurities ( Filtration), then the droplets will form a larger drop. (Coalescence) through multiple filters and finally, gravity will cause water droplets, which are denser than oil, to precipitate down to the bottom of the Coalescer (Separation) Coalescer 3; Samples and looks Coalescer: Continue reading What is Coalescer or coalescence filter?
What is Hoop Stress in pressure vessel?
Stress in Cylindrical Component 1; Pressure or pressure within a component that is cylindrical (Cylinder) will cause stress or stress on the component, both the longitudinal stress ( Circumferential stress). Stress in Cylindrical Component 2; Considering the cylindrical Vessel and Pipe, which have the Longitudinal Weld and the Circumferential Weld, we see that the Longitudinal stress is dealt with the Circ. Weld and stresses along the circumference ( circumferential stress) are done with the Long. the Weld. Stress in Cylindrical Component 3; Normally, the circumferential stress is twice that of the longitudinal stress observed in daily life. We will see that the sausage will always break … Continue reading What is Hoop Stress in pressure vessel?
