Description

Technical Field

[0001] This utility model relates to the field of gas pipeline corrosion protection technology, specifically to a reinforcement and corrosion protection structure for the connection of a gas transmission pipeline. Background Technology

[0002] The connections of gas transmission pipelines with varying diameters, such as elbows, tees, crosses, or Y-tees, are collectively referred to as gas transmission pipeline connections. Inspection of the anti-corrosion layer at these connections reveals that after 2-3 years of operation, the anti-corrosion layer cracks and fails, leading to grounding corrosion. If not addressed promptly, the anti-corrosion layer will quickly corrode and perforate, causing gas leaks in the transmission network and even potentially resulting in a deflagration accident.

[0003] Existing gas pipeline connection reinforcement and corrosion protection structures achieve this by spraying an anti-corrosion layer and a reinforcement layer on the outside of the gas pipeline connection. However, with the increase of service time, the anti-corrosion layer will undergo irregular deformation due to the characteristics of thermal expansion and contraction, resulting in cracking. This leads to a shorter service life of the anti-corrosion structure and affects the overall operation of the gas pipeline network. Therefore, there is an urgent need for a new reinforcement and corrosion protection structure for gas pipeline connections to solve the above problems. Utility Model Content

[0014] Further, the insulating layer is attached to the outside of the graphene layer, and the insulating layer is made of insulating heat-conductive material and has a thickness of 2 mm.

[0019] By adopting the technical scheme, the protective layer can protect the reinforcing layer and the anticorrosive layer.

[0020] Further, the wire is electrically connected to the graphene layer and the temperature controller, and the temperature controller is fixed on the top of the connection between the first gas pipeline and the second gas pipeline by a support.

[0021] By adopting the technical scheme, the temperature sensor built in the temperature controller can detect the temperature of the outside environment, and when the detected value is less than a set value, the graphene layer is controlled to generate heat through the wire.
