Description

Technical Field

[0001] The utility model relates to a heat dissipation device for a weld of a bimetallic composite pipeline, belonging to the technical field of metal pipeline welding equipment. Background Art

[0002] Metal pipe welding is widely used in fields such as petrochemicals, construction, and natural gas transportation projects. Pipeline welding is used to ensure the sealing and pressure resistance of pipelines. The quality of welding directly determines the stability and safety of the process. Since the natural ventilation and heat dissipation time required for the welds of metal composite pipes after welding is long, it is impossible to control the minimum temperature and insulation time after heat dissipation. The heat dissipation and cooling requirements of the welds of bimetallic composite pipes are high. If the requirements cannot be met through natural heat dissipation, the welds may crack, affecting the progress and quality of the project. Currently, there is no dedicated heat dissipation device for the welds of metal composite pipes. Heat is generally dissipated through natural ventilation, which requires a long time for natural heat dissipation and the insulation time of the minimum temperature after heat dissipation cannot be controlled. The cooling effect is poor. If the heat dissipation does not meet the requirements, the welds may crack, greatly reducing work efficiency. There is an urgent need for equipment that can effectively cool the welds of metal composite pipes to ensure heat dissipation time and welding quality and eliminate the hidden dangers of weld cracking.

[0017] The diagram shows that the upper and lower heat dissipating copper rings 3 and 4 are semi-circular copper rings, each with an inner diameter that matches the outer diameter of the bimetallic composite pipe. Horizontal connecting plates 5 face each other on either side of their lower ends, each with corresponding holes. Connecting bolts 6 and nuts 7 connect the upper and lower heat dissipating copper rings 3 and 4 through the holes in the connecting plates 5 to form a circular ring. The ring is then fitted around the weld joint of the bimetallic composite pipe. Cooling water is contained within the upper and lower heat dissipating copper rings 3 and 4, dissipating heat and cooling the weld joint of the bimetallic composite pipe covered by the upper and lower heat dissipating copper rings 3 and 4.

[0018] The figure shows that the outer walls of the upper heat dissipation copper ring 3 and the lower heat dissipation copper ring 4 are respectively provided with an inlet pipe interface 10 and a return pipe interface 11. The inlet pipe interface 10 and the return pipe interface 11 are threadedly connected to the outer walls of the upper heat dissipation copper ring 3 and the lower heat dissipation copper ring 4, respectively. The inlet pipe interface 10 and the return pipe interface 11 are connected to the inlet pipe 8 and the return pipe 9, respectively.

[0019] The diagram shows that the water inlet pipes 8 of the upper and lower heat dissipating copper rings 3 and 4 are connected to the return port of the water tank 1 via the water pump 2.

The water pump 2 is started to drive the water in the water tank 1 into the upper heat dissipation copper ring 3 and the lower heat dissipation copper ring 4 through the water inlet pipe 8, and then flows back to the water tank 1 through the return pipe 9. The water absorbs the heat of the heat dissipation copper ring during the flow circulation process, and makes full use of the principle of good thermal conductivity of the heat dissipation copper ring to absorb the heat at the pipe weld for heat exchange to achieve the purpose of heat dissipation of the weld. The temperature of the circulating water in the water tank 1 is monitored by the control mechanism. The operator adjusts the speed of the water pump 2 according to the water temperature to control the flow rate of the circulating water, thereby accelerating the heat dissipation of the weld, improving the heat dissipation efficiency, and ensuring the heat dissipation effect.
