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?
Certification Mark UV, U, V stamp (ASME VIII)
Certification Mark of Section VIII PRV (UV Stamp); The Pressure Relief Valve (PRV) designed according to ASME Section VIII regulations will be stamped with the symbol “UV “. Required Marks on Nameplate of ASME Section VIII Vessels; Marking on the Nameplate of ASME Section VIII (“U” Stamp) Pressure Vessels must have at least Vessel information as in the picture below: Certification Mark of ASME Section VIII Vessel (U Stamp); Pressure Vessels designed and built according to ASME Section VIII regulations must be stamped with the symbol ” U “. Certification Mark of ASME Section I PRV (“V” Stamp); Pressure Relief Valve (PRV) designed in accordance with ASME Section I (Power boiler) requirements. Power Boiler must be stamped … Continue reading Certification Mark UV, U, V stamp (ASME VIII)
What is Rupture Disc?
Rupture Disk; Rupture Disk is a pressure relief device that does not close. (Nonreclosing) by releasing the pressure when the Disk breaks ( Burst) at Burst Pressure Rupture Disk is often used together with Pressure Relief Valve (PRV) to prevent corrosion from the process fluid touching PRV. Rupture Disk – Installation; The Rupture disk installation is directly between the Rupture disk and the PRV. There must be a Vent Pipe or Pressure Gauge to check if the Disk is leaking or cracking. When we remove the disk for inspection or maintenance, the PRV should replace the disk because the Disk … Continue reading What is Rupture Disc?
What is Field Metallographic Replica?
Field Metallographic Replication (Replica) 1; Field Metallographic Replication, or Replica, is the peeling of a workpiece and used in an endoscope. Microstructure To indicate features and changes Metallurgy (Metallurgy) of the workpiece. Field Metallographic Replication (Replica) 2; How do Field Metallographic Replication (Replica) Continue reading What is Field Metallographic Replica?
What is MAWP of pressure vessel (ASME VIII)
MAWP of Vessel per ASME VIII; Maximum Allowable Working Pressure (MAWP) of the Pressure vessel is a Maximum Pressure of Vessel part at least, a strong will can be obtained by measuring the Pressure at the Top of the Vessel MAWP of Vessel per ASME VIII – Example; For example, the Maximum Allowable Working Pressure (MAWP) of the Vessel in Strength Calculation Sheet. Further discussion on MAWP and Design Pressure: Design Pressure Vs MAWP (API, ASME) Continue reading What is MAWP of pressure vessel (ASME VIII)
Pressure Vessel Full Vacuum condition
Full Vacuum Condition (FV) per ASME VIII; The design pressure of the pressure vessel in accordance with ASME Section VIII that is specified as FV or Full Vacuum is the state in which the internal pressure vessel is vacuum (Absolute pressure = 0 kPa) and external pressure is equal to 100 kPa which is approximately the atmospheric pressure. Continue reading Pressure Vessel Full Vacuum condition
What is Built-up Backpressure of PRV?
Continue on: What is Backpressure, Superimposed Backpressure? Built-up Backpressure of PRV; Built-up back pressure is the pressure that will occur when the pressure relief valve (PRV) opens and the pressure is released. This is because there Head/friction loss (Pressure drop) in the pressure relief system: Example of PRV Backpressure; Example of Backpressure Calculation of Pressure Relief Valves (PRV) in the system Continue reading What is Built-up Backpressure of PRV?
