Pressure Testing Procedures for Ai Yuan HDPE Composite Underground Piping Systems at Fuel Stations Pressure testing is one of the most critical quality assurance steps when installing underground composite piping at fuel stations. For Ai Yuan (HDPE + EVOH + conductive masterbatch composite) systems, proper pressure testing confirms that every electrofusion joint, adapter connection, and […]
Introduction Stage III vapor recovery systems have become a cornerstone of modern gasoline station design, particularly in regions with strict environmental regulations. These systems capture gasoline vapors displaced during vehicle refueling and return them to the station underground storage tank, preventing volatile organic compounds from escaping into the atmosphere. However, the effectiveness of any Stage
