Pressure vessels are extensively useful in various industries such as petroleum, food and beverage, pharmaceutical, chemical, oil and gas, etc. The capacity of storing fluids as well as gases under immense pressure makes these vessels prone to accidents and mishaps.
It is essential to follow prescribed safety measures for pressure vessels when it comes to the manufacture and operations. Below are basic guidelines that will help end users to safeguard against any plausible mishaps:
Select High Quality Raw Material: Material must be selected appropriate to the intended service. It is the intended user and/or the EPC contractor who need to make the appropriate material selection. Consideration should be given to corrosion, erosion, thermal stresses, cyclic pressure stress and other factors affecting the pressure boundary materials. The material must be able to withstand the most harsh working environment. Any cracks or damage to the pressure vessel structure can lead in leakage or operational failures in the pressure vessel.
Utilize Safety Valves and Pressure Release Systems: Severe accidents can occur if a pressure vessel is exposed to an excessive pressure or temperature. In order to prevent over-pressurization, safety valves and/or pressure release systems must be used. When vessels are exposed to higher temperatures, thermal controls should be monitored as well.
Adhere to Safety Standards and Codes: In addition to the ASME BPVC Standards Section VIII which governs the design and manufacture of pressure vessels, pressure vessel users should adhere to safety standards and codes such as OSHA (Occupational Safety and Health Administration) 1915 Subpart K for vessels, drums, and containers, API 510 Vessel Code for maintenance, repair, and alteration and API 572 for Inspection. Local jurisdiction authorized inspection agencies govern and regulate inspections and installations.
Allow Trained Personnel to Handle Pressure Vessels: Because of the high risk factor involved while working with pressure vessels, it is important that only trained personnel be allowed to handle the vessels.
By following the aforementioned tips, you can be assured of a safe manufacturing as well as utilization experience with pressure vessels.
