At present, the underwater pipeline wet insulation used in China is all manufactured by foreign contractors, and foreign wet insulation materials are used, resulting in a long construction period, high risk, and high cost. The underwater pipeline has a complex structure: the pipeline includes straight pipe sections, elbows, and tees. For the wet insulation coating of these parts, molds with corresponding shapes need to be prefabricated for the formation of the wet insulation coating. During the curing and forming process of the wet insulation coating, the mold needs to maintain a certain temperature, usually 60 - 80°C. In addition, due to the generally large volume of underwater pipelines, the wet insulation coating construction needs to be carried out at the underwater pipeline production site; due to the complex internal structure of the underwater pipeline and narrow working surfaces, mechanical or automatic installation of the mold cannot be achieved during the wet insulation coating construction, and only manual installation is possible; due to the complex structure of the underwater pipeline, including pipe fittings of different shapes, the heating system needs to be able to adapt to molds of various different shapes and sizes.
