What is the difference between rubber flexible joints and insulation joints?

Many people will confuse rubber joints with insulation joints, thinking that they are the same, but this is wrong.
The main component of the rubber soft joint is composed of rubber and metal flange, the structure of the insulated joint is different from it.
Insulation joint is a generic term for a pipe joint that has both sealing performance and strength performance required by buried steel pipeline and insulation performance required by electric corrosion prevention. It contains combination parts, insulating plate, packing, sealing ring, short pipe, etc.
Insulation joint is a replacement product improved according to the problems of insulation flange in use. It is an essential and important pressure element in the protection system of steel pipeline, and is widely used in the protection system of steel pipeline.
Insulation joints are installed differently from rubber flexible joints. It is important to install insulation joints effectively, and after installation, both normal use and service life can be guaranteed.
