Pressure Vessels

Pressure vessels are containers that are designed to withstand a minimum level of internal pressure up to 15psig. They can be used to contain many types of substances such as air, water, chemicals, nitrogen, and fuel. These vessels can help in the transportation, storage and control of these different substances. Pressure vessels are often used to control temperatures as well as pressure. These devices are commonly used in many types of industries such as: cosmetics, pharmaceutical, chemical, food and beverage, oil and fuel, paper and pulp, the plastics industry and the power generation and energy industry. Boilers and even domestic pressure cookers are good examples of pressure vessels.

When chemicals and other products are heated or are undergoing a chemical reaction, a certain amount of pressure is either generated or applied. The pressure vessel is used to cook with pressure in a safe manner. These vessels have a rated pressure and should not be operated at pressures beyond the rated value since they may burst and could cause severe injuries and even death. Because of their potential danger, pressure vessels are fitted with safety valves that open up when the target pressure is exceeded. Alarm devices can also be fitted and sound a warning at the appropriate pressure.

Pressure vessels are made of high quality steel plates which are welded and riveted together. Pressure vessels are also fitted with pressure indicators, pressure gauges, control valves, piping, and tubing, etc. Important parameters to be considered while selecting a pressure vessel include the rated pressure, the internal volume, and the maximum temperatures, etc.

Since pressure vessels contain materials at very high pressures it is very important that you keep them in proper working order. If a vessel was to break or a seam was to rupture it could easily result in an injury due to shrapnel and dangerous chemicals escaping. You should visually inspect these devices regularly and you can even inspect them closer by using x rays on them. Make sure that you only buy pressure vessels that have been certified as safe. These certified and approved units have been inspected and conform to industry-wide standards of strength.
