Pressure vessels, also referred to as vacuum receiver vessels, serve as storage containers designed to hold fluids or gases under pressure. Typically, the pressure and temperature within these vessels are higher than the surrounding environment. They commonly feature a cylindrical shape with dished ends and can be oriented vertically or horizontally based on specific needs. The types of vessels vary depending on the construction material, typically including glass-lined, mild steel, and stainless steel variants. Engineering firms and specialized fabricators are responsible for their construction. Pressure vessels find application across a range of industries, including chemical, petrochemical, pharmaceutical, and oil and gas sectors.
