A pressure vessel is a specialized container designed to safely hold gases or liquids at pressures significantly different from ambient pressure. Constructed from materials like steel, stainless steel, or composite materials, it features robust walls to withstand internal and external pressures. The vessel can be cylindrical, spherical, or any other shape suited to its application. Key components include reinforced walls, pressure relief valves, and various fittings for monitoring and accessing contents. Pressure vessels are crucial in industries such as chemical processing, oil and gas, and power generation, where they manage high-pressure processes. They adhere to strict safety standards and regulations to ensure safe operation, durability, and efficiency. Designed for reliability, pressure vessels are integral to maintaining system performance and preventing hazardous incidents.
