What are the factors affecting the performance of Marine flanges?
In the production of Marine flanges, there are many factors that affect its performance. Below, follow the aluminum alloy flange editor to see what are its common factors!
Annealing temperature: Annealing temperature is the temperature parameter of primer and template binding, which is an important factor affecting the specificity of PCR. Under ideal conditions, the annealing temperature is low enough to guarantee effective annealing of the primer sequence with the target sequence, and high enough to reduce non-specific binding. Reasonable annealing temperature from 55℃ to 70℃.
Second, the sealing of the furnace body: the furnace shell is welded by steel plate and steel plate, and the trolley is welded by steel plate and steel plate. The car is in soft contact with the furnace lining and sealing sand mechanism to reduce heat radiation and convection loss and effectively ensure the furnace body seal. Bright annealing furnace should be closed and isolated from the outside air. When hydrogen is used as a protective gas, only one outlet is open (to ignite the discharged hydrogen). The method of inspection can be used to wipe soapy water on the cracks of each joint of the annealing furnace to see whether the gas is running. Among them, the place that is easy to run gas is the place where the annealing furnace enters the pipe and the place where the pipe comes out, and the sealing ring of this place is particularly easy to wear, and it is necessary to check and change often.
Third, the protection gas pressure, in order to prevent micro-leakage, the protection gas in the furnace should maintain a certain pressure, if the protection gas is hydrogen, 20kBar the above general requirements. Annealing atmosphere: Pure hydrogen is usually used as an annealing atmosphere, the atmosphere is preferably 99.99% purity or higher, when the other part is an inert gas atmosphere, then the purity may be lower, but cannot contain too much oxygen, water vapor.
The above is the small edition of this aluminum alloy flange to introduce the performance factors affecting Marine flanges, I hope to help you.
