Introduction to GB150

GB150, or the Chinese national standard series for pressure vessels, includes comprehensive guidelines for the design, manufacture, inspection, and acceptance of metal pressure vessels. The standard is segmented into multiple parts, covering general requirements, materials, design specifics, and manufacturing processes. For example, GB150.1-2011 outlines general requirements, providing frameworks for managing safety, regulatory compliance, and technical specifications essential for safe and effective pressure vessel operation. It serves industries where pressure vessels are crucial, such as chemical processing, oil and gas, and power generation. Powered by ChatGPT-4o
