Insulation joint
Good insulation property, sealing property and rigidity are the basic requirements of insulation joint structure.
The insulation joint is mainly composed of left and right conduit, flange, fixing sleeve, insulation packing, insulation gasket and o-type sealing ring. The right pipe is welded to flange and fixing sleeve, and the left and right pipe are separated by insulation material to achieve insulation effect. Under the action of preload, the o-ring has a certain amount of compression and forms an initial seal.
In practical engineering, the insulation joint is most likely to cause leakage under the action of external bending moment.Therefore, the hydraulic pressure and bending moment test should be carried out so as to verify the overall structural stability of the insulation joint.
