Heavy-duty pressure vessels are robust containers designed to safely hold gases or liquids at high pressures. Constructed from high-strength materials such as steel or specialized alloys, these vessels are built to withstand extreme internal pressures and harsh operating conditions. They are commonly used in industries like chemical processing, oil and gas, and power generation. Key features include reinforced walls, thick linings, and advanced welding techniques to ensure structural integrity and prevent leaks or explosions. Heavy-duty pressure vessels often come with safety valves, pressure gauges, and temperature controls to manage and monitor operational conditions. Their design and fabrication must comply with stringent standards and regulations, ensuring reliability and safety in demanding applications.
