Overall advantages of cryogenic storage tank
Three quality inspection measures are adopted for the manufacturing process of the inner cylinder of the low-temperature storage tank of Suzhou Doer Gas Chemical Equipment Co., Ltd., one is 100% flaw detection of all welds on the inner cylinder, the other is gas pressure test on the inner cylinder, and the third is helium mass spectrometry leak detection on the inner cylinder. The manufacturing requirements of our company are more stringent than the national standard gb18442. The outer cylinder and pipeline are also leak picked up by helium mass spectrometry, which greatly improves the safety and quality!
The low-temperature storage tank of Suzhou Doer Gas Chemical Equipment Co., Ltd. adopts internal and external surface sandblasting in the manufacturing process of the outer cylinder. The internal surface sandblasting completely removes the impurities unfavorable to vacuum pumping, such as oil stain, welding coating and oxide skin, which can ensure that the vacuum quality of the storage tank meets the national standard, and the external surface sandblasting requirements meet Sa2.5 to ensure the paint quality, It can ensure that the tank paint will not rust for three years.
The inner and outer surface pickling process is adopted in the manufacturing process of the inner cylinder of the low-temperature storage tank of Suzhou Doer Gas Chemical Equipment Co., Ltd., which ensures the cleanliness of the inner and outer surfaces of the inner cylinder of the low-temperature storage tank and the vacuum of the low-temperature storage tank.
The thermal insulation material pearlescent sand used in the low-temperature storage tank of Suzhou Doer Gas Chemical Equipment Co., Ltd. is the hot pearlescent sand loaded in the storage tank. After loading the sand, the evacuation is very fast and the evacuation quality is good.
All butt welds of pipes used for low-temperature storage tanks of Suzhou Doer Gas Chemical Equipment Co., Ltd. require 100% X-ray flaw detection, and all adopt argon arc welding to ensure the vacuum quality of products.
