Abstract
Description
Technical Field
[0001] The utility model relates to the field of gas pipelines, in particular to a temporary temperature-raising device during a gas pipeline pressure test. Background Art
[0002] The main sources of gas are liquefied petroleum gas, coal gas and mixed air, and the gas is transported by gas pipelines. The pipeline that transports natural gas (including associated gas produced by oil fields) from the mining site or processing plant to the urban gas distribution center or industrial enterprise users is also called a gas transmission pipeline. The outer layer of gas pipelines on the market is usually made of plastic material, and traditional gas pipelines will harden the outer wall of the pipe body when in use, especially in low temperature environments, affecting the use of gas pipelines. Therefore, gas pipelines need to be insulated;
[0003] The electric heating element of the temperature-controlled electric heating cable is a core belt made of a layer of PTC material uniformly extruded between two parallel metal busbars. After the PTC material is melted, extruded, cooled and formed, the carbon particles dispersed in it form countless fine conductive carbon networks. When they are connected across two parallel busbars, they form a PTC parallel circuit of the core belt. When the two busbars at one end of the cable are connected to the power supply, the current flows horizontally from one busbar through the PTC material layer to the other busbar to form a parallel circuit. The PTC layer is a resistance heating element continuously connected in parallel between the busbars, which converts electrical energy into thermal energy to heat and insulate the gas pipeline.
[0004] When installing the electric heating cable, the electric heating cable needs to be wrapped around the gas pipeline. The traditional gas pipeline is placed on the ground, and it is very inconvenient to operate when wrapping the electric heating cable. When wrapping a small gas pipeline, it often requires cooperation between multiple workers. The gas pipeline needs to be lifted up for wrapping, which increases the workload. Utility Model Content
