What is the internal structure of the flange connection loose-fitting limit compensation joint?
During the assembly process, the housing is removed from the liquid nitrogen and inserted from both ends. If the temperature rises to the normal temperature, the temperature can be changed by electric heating. The shape memory alloy deformation of flange joint loose sleeve limit compensation joint is formed by the shrinkage of flange joint loose sleeve limit compensation joint processing, which achieves tight oil leakage and is greatly superior to traditional welding. Therefore, flange joint loose set limit compensation joints are especially suitable for aerospace, ships, oil pipelines and other fields.
In places where construction is inconvenient, the pin can be made of flange connection loose sleeve limit compensation joint and heated in the hole. Therefore, the use of flange connection loose-fitting limit compensation joint temperature-sensitive drive multiple functions, combined with the structure of nickel-titanium alloy shape memory alloy, can improve the damping of the system and reduce the dynamic response of the structure, thus creating various types of damping energy dissipation devices.
Flange-connected loose-fitting limit compensating joints can also be designed with flange-connected loose-fitting limit compensating joints. The deformation of flange-connected loose-fitting limit compensation joints can increase the dissipation of deformation displacement and prevent transmission to the upper structure, thus protecting the upper structure and improving the seismic performance of the structure.
Flange jointed loose-fitting limit joints can be freely bent into various angles and radii of curvature, and have the same flexibility and durability in all directions. Flange joint loose sleeve limit compensation joint is flexible in pitch, pliable, unobstructed and rigid. Stainless steel threading flange joint loose sleeve limit compensation joint has a certain tension between the side buckles to prevent damage to the flange joint loose sleeve limit compensation joint due to damage.
The axial tension can withstand more than 6 times of the nominal inner diameter. Therefore, flange joint loose set limit compensation joint is easy to install and low efficiency can be utilized to achieve energy saving effect. Generally, pure hydrogen is used as the annealing atmosphere of flange jointed loose-fitting limit compensation joint, and the purity of the atmosphere is recommended to be 99.99% or more. If there is another inert gas in the atmosphere, the purity of pure hydrogen can be reduced appropriately, but it is prohibited to contain excessive oxygen and water vapor. The method of inspection is to wipe the water in each joint gap of the annealing furnace and observe whether there is any gas leakage, in which the part that is easy to leak is the place where the annealing furnace enters and leaves the tube, the seal here is very easy to wear, and needs to be checked and replaced frequently.
