项目名称: Wuhan Friendship Food Edible Oil Pipeline Maintenance and Electric Heat Tracing Project
Wuhan Friendship Food Engineering Co., Ltd. was established in 1995 and is headquartered in Guannan Science and Technology Park, Donghu High-tech Development Zone, Wuhan. The company’s main business and service scope include: design and manufacture of various large non-standard grease equipment, large pressure vessels, etc. ; Undertake grease engineering management, provide grease engineering EPC solutions; manufacture and export large-scale chemical equipment and steel structure equipment that meet European PED and American ASME standards; design and manufacture various grain and oil mechanical transportation equipment.
Due to the high viscosity of the edible oil production and the low temperature in winter, the edible oil is easy to condense and block the pipeline, which brings inconvenience to the production and transportation. Therefore, it is necessary to take anti-freezing and thermal insulation measures for the edible oil pipeline, and the electric heat tracing insulation system is a kind of The ideal heat preservation method, it does not contact the medium in the pipeline, and evenly releases heat along the length of the pipeline or the large area of the tank body. The heat preservation effect is very good, and it can ensure the normal operation of the edible oil pipeline.
According to the comprehensive factors such as temperature requirements, environmental characteristics and power supply conditions of the project, the selected electric heating cable model is RDYC3(Q)-J3(4) three-core series constant power electric heating cable. The series constant power electric tracing cable continuously releases energy through the current energizing conductor to form a continuous, uniform heating electric tracing cable. It has a long use length, which is 5-12 times longer than the length of self-limiting temperature electric heating cables and ordinary constant power electric heating cables, and is suitable for antifreeze and thermal insulation of long-distance pipelines.
It should be noted that the serial constant power electric heating cable cannot be cut arbitrarily. It needs to be designed according to the actual length of the pipeline. The installation should be carried out in strict accordance with the designed length during installation. Too long or too short will affect the overall power of the electric heating cable. The electric heating cable is cut at will, otherwise it will cause the whole electric heating system to malfunction.
The serial constant power electric heating cable has a small number of loops, which is easy to bend and has few nodes, which is easy to install, control, detect and manage. It has been widely used in long-distance pipelines, large tanks, oil tanks, etc. in the petroleum, chemical, electric power, and dock industries Antifreeze, heat preservation and heat tracing.
