API Std 650 stainless and carbon steel tank metal-seated ball valve
Under the same sealing effect, the internal API Std 650 stainless and carbon steel tank floating roof API 650 tank can further reduce the evaporation loss compared with the external floating roof API 650 tank. This is due to the shielding of the fixed roof and the gas phase layer between the fixed roof and the inner floating plate, which has more significant heat insulation effect than the double disc floating roof of the API Std 650 stainless and carbon steel tank external floating roof tank.
The thickness of the API Std 650 stainless and carbon steel tank wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 0.57 in. The nozzle neck is seamless steel pipe and conforms to ASTM A53, Grade A; the materials in the tank wall and reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank walls are fully radiographed, double-welded butt joints. The adequacy of the reinforcement and attachment welds shown in Figure F-7 shall be determined.To determine the length of the nozzle neck within the limits of reinforcement, the smaller of the following calculated values shall be used:(2.5)(0.625) = 1.56 in. (2.5)(0.375) + 0.75 = 1.69 in.
The cleanliness of the API Std 650 stainless and carbon steel tank has a great influence on the safety of the tank and the quality of the oil stored. Keeping the API Std 650 stainless and carbon steel tank clean can slow down the corrosion of the tank wall and reduce the pollution to the oil. If the inside of the API Std 650 stainless and carbon steel tank is not cleaned all the year round, a lot of rust and metal impurities will be produced in the tank. These impurities will cause the oil to slowly oxidize and deteriorate. The impurities mixed into the oil will also block the filter and oil circuit, causing oil supply failure.
Corporate mission: to provide high quality steel products API Std 650 stainless and carbon steel tank and services to global customers.Strategic goal: to be the leading steel materials supplier in the world.Enterprise core values: people-oriented, customer first, quality oriented, comprehensive and open, continuous innovation.Customer first is to always put the satisfaction of customer needs first. The key point is "customer centered". We should consider what customers need us to do, what we have done for them, what else we can do for them.
As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's API Std 650 stainless and carbon steel tank steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole API Std 650 stainless and carbon steel tank steel transportation industry.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
