Compact Insulation Joints
Insulation joints are piping parts that are used to break conductivity of steel pipelines in the points where pipes are separated by insulation. They are especially applied in cathodic protection systems.
Insulation joints are piping parts that are used to break conductivity of steel pipelines in the points where pipes are separated by insulation. They are especially applied in cathodic protection systems. Compact insulation joints of SHD type have been designed with circular spark gap (Patent mo. 389367), which ensures their high reliability in operation and longer service life as compared to the systems equipped with the spot type of the spark gap. They are characterized with compact, highly mechanically resistant structure which is applicable in underground pipelines as well as in the overhead ones. They are produced in wide range of dimensions and versions, for various media, with various connecting ends, external and internal anti-corrosion protection, etc. Particular specification for each type of insulation joints is indicated in the following data sheets. On request, insulation joints may be also supplied in accordance customer’s requirements and specifications.
