Air Tank takes important role in mining, petroleum, chemical, pharmacy, textile, construction, boiler industry. Tank can slow down compressed air and make it smooth. At the meanwhile, it can collect water from cool air and exhaust out of the system. It like a storage to ensure air supply during rush hours. It can eliminate and weaken the periodic pulsation of air compressor which store compressed air, maintain steady pressure, and supply air into the pipe in a short time, and cool down compressed air, exhaust some water and dirt.Simple pressure vessel structure is less dangerous than other vessels.Small volume: less than 1000LLow pressure: designed max pressure less than 1.6Mpa.Safe media: air, nitrogen or steam from medical distilled waterSuitable temperature: -20℃-150℃.Small volume(below 1000L)and low pressure(less than 1.0Mpa) make it safer.Made by steel strip and steel sheet, easy to coordinate if deformed. Stress concentration is not obvious. Low stress level, high weldability and toughness, thus less damage to brittle failure.
