The last line of defense for protecting storage tank safety – emergency relief valves

Thread Content

1. The SH3007 storage and transportation tank area specifications also have relevant requirements; section 5.1.5 stipulates that storage tanks protected by nitrogen or other inert gases as a sealing mechanism must be equipped with emergency pressure relief devices. 2. At present, there are no national standards for emergency relief in China; generally, the relevant provisions in the \"Regulations on Safety Inspection of Pressure Vessels\" are referred to, and compliance with API 650 or API 2000 standards (standards issued by the American Petroleum Institute) is also required. 3. At present, the manufacturers in the domestic market are of poor quality; substandard products are widespread, posing a serious threat to the safety of users’ storage tanks. Some pipe fitting factories in Hebei produce products that are essentially just for show; under normal conditions they leak severely, and in emergency situations they are unable to release gas at all, as no pressure testing is carried out before they leave the factory. 4. Having been in sales for over a decade, I’ve seen many purchasers who only look at the lowest price, ignoring the quality of the products altogether. After all, if something goes wrong, they can blame the manufacturer – it has nothing to do with the purchaser, which is really frustrating. 5. The market is currently highly competitive, and in order to survive, many competitors focus on reducing costs – doing whatever it takes to save money. Few focus on improving quality, on making their products better.
