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.
