Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection insulation, in particular to a pipeline quick-install insulation joint. Background Art

[0002] The main reason for insulation when connecting steel pipes and prestressed steel cylinder concrete pipes is indeed to prevent electrochemical corrosion, also known as galvanic corrosion or bimetallic corrosion. This corrosion is caused by the formation of a galvanic effect when two different metals or alloys come into contact in an electrolyte solution (such as moisture in the soil or groundwater). In order to prevent this, an insulating head needs to be installed between the steel pipe and the prestressed steel cylinder concrete pipe to cut off the circuit of electrochemical corrosion. The insulating head provides an electrical isolation layer that blocks the flow of current, thereby protecting the two metal materials from the influence of electrochemical corrosion. The existing insulating head has a single connection port position and size, slow connection, and poor practicality. Utility Model Content
