The insulation joint is a new generation product based on the problems existing in the use of insulation flange. It is an essential and important pressure element in the cathodic protection system of steel pipeline and should be widely used in the cathodic protection system of steel pipeline. The insulation joint of our company refers to the latest foreign product structure and adopts a unique design, which overcomes the disadvantages such as small insulation flange stiffness, easy leakage, can not be buried in the ground, short life and so on, and realizes the buried maintenance-free function, so that the service life of the insulation joint is the same as that of the supporting pipeline.
YY-JT series insulation joint
The insulation joint is an essential pressure element in the cathodic protection system of steel pipeline. Our insulation joints refer to the latest foreign product structure, adopt a unique design and comply with ASME BPV Code Sect Ⅷ Div.Ⅰ Appendix2 design specifications and ASME B31.3 design criteria, overcome the disadvantages of low insulation flange stiffness, easy leakage, can not be buried, short life and so on. The function of maintenance free buried in the ground is realized, so that the service life of the insulation joint is the same as the supporting pipeline.
3、Service life: the same as the pipeline
4、Suitable medium: oil, gas, water, chemical raw materials, pulp
5、End groove: in accordance with ASME B31.4 and welding procedure
6、Installation position: horizontal buried
Example: Insulation joint with nominal diameter DN400, design pressure PN25 and length of 1000mm, model number marked YY-JT2.5/400-1000
