【Common Issues in Haichuan Pipeline Design】--For materials that cause chemical burns, fragile materials such as glass are used for pipeline connections, installations, and observation areas

Thread Content

During the design, installation, and inspection of pipelines, various minor issues that have been overlooked or not taken into consideration are often identified. These issues are compiled into a series; the list is being updated continuously. Everyone is welcome to actively participate in discussions. This is a compilation post on common problems in Haichuan pipeline design – it’s still being updated, and discussions are welcome: https://bbs.hcbbs.com/thread-5705828-1-1.html ------------------------------------------------------------------ For descriptions of potential hazards: For materials that can cause chemical burns, fragile materials such as glass should not be used for pipeline connections, installations, or other related components. The relevant standard is GB20571-2014, \"Code for Safety and Health Design in Chemical Enterprises\", section 5.6.2. Operations involving chemical burn hazards should be carried out using mechanical, pipelined, and automated methods, with necessary signal alarms, safety interlocks, and protective devices installed. Pipes, fittings, valves, flow meters, pressure gauges, etc., made of fragile materials such as glass must not be used.
