Due to the volatility of oil products, the volatile consumption of oil products is inevitable in the storage process of large oil storage tanks such as china big diameter heavy longitudinal submerged arc. The volatilization of oil causes economic losses and pollution to the environment. Especially in the open air environment, large-scale oil storage tanks in the petrochemical industry will continue to accumulate energy when exposed to the sun, causing their surface and interior to heat up rapidly, causing sun overheating, and accelerating the volatilization of oil. How to effectively reduce the volatile consumption of large oil storage tanks?
Jun 01, 2018 · Analysis of aerobic granular sludge formation based on grey system theory.. PubMed. Zhang, Cuiya; Zhang, Hanmin. 2013-04-01. Based on grey entropy analysis, the relational grade of operational parameters with aerobic granular sludge's granulation indicators was studied. The former consisted of settling time (ST), aeration time (AT), superficial gas velocity (SGV), height/diameter Why is submerged arc welding used in line pipe manufacturing?Submerged arc welding is ideally suited to the longitudinal and circumferential butt welds required for the manufacture of line pipe and pressure vessels. Welding is normally carried out in the flat (BS EN ISO 6947 PA) position because of the high fluidity of the weld pool and molten slag and the need to maintain a flux layer.See all results for this questionWhat is arc welding?The arc is submerged beneath the flux blanket and is not normally visible during welding. This is a well established and extremely versatile method of welding. The electrode may be a solid or cored wire or a strip made from sheet or sintered material.See all results for this question
submerged arc. A variety of welding flux and wire designed to be paired together to meet any industry specific welding requirement.See all results for this questionWhat is Submerged-arc Welding? - TWISubmerged arc welding is ideally suited to the longitudinal and circumferential butt welds required for the manufacture of line pipe and pressure vessels. Welding is normally carried out in the flat (BS EN ISO 6947 PA) position because of the high fluidity of the weld pool Submerged Arc Welding Process - TWIThe first patent on the submerged-arc welding (SAW) process was taken out in 1935 and covered an electric arc beneath a bed of granulated flux. Developed by the E O Paton Electric Welding Institute, Kiev, during the Second World War, SAW's most famous application was on the T34 tank.
