KL type finned tube: Before the fins are continuously wound on the surface of the steel pipe, the outer surface of the base pipe needs to undergo a knurling process; after the KL fin tube fins are wound, the root of the fin attached to the steel pipe will also be knurled to strengthen the steel pipe and Combination of fins. For this reason, this KL fin tube type ensures better heat transfer characteristics under the fins of L and LL. Maximum working temperature-260°C (500°F), acceptable for atmospheric corrosion resistance, poor mechanical resistance. Commonly used heat sink materials are aluminum and copper.

Yang Lanming, president of the Xingtai Chemical Industry Association, told the reporter that the planned and constructed soda ash chemical industry chain is based on the local reserves of rock salt as raw materials, supplemented by local and peripheral coal resources, and the soda ash process to develop soda ash industry. Planning and development of NPK compound fertilizer, sodium percarbonate, sodium bicarbonate, sodium chloride and other soda ash, ammonium chloride downstream products, in order to increase product variety and extend the product chain, increase the added value.
The chlor-alkali industry chain plans to use local rock salt as raw material to produce whole-halogen caustic soda to achieve a large coal, electricity, salt, and alkali combination and enhance cost competitiveness. At the same time, we will further extend the product chain and focus on the development of organic silicon series, chlorine trichloride-polysilicon series, methane chloride-organic fluorine series, chlorinated aromatic series, chlorination titanium dioxide, chloroisocyanuric acid, chlorine Polychlorinated and other chlorine-consuming fine chemicals and new chemical products; alkali-alkali production, focusing on the development of viscose fiber, layered sodium silicate and sodium metasilicate, etc.; hydrogen is mainly used for the production of hydrogen peroxide to meet papermaking, textile and green hydrogen peroxide Propylene oxide and other industries demand.
The coal chemical industry chain utilizes coal resources and cheap coke oven gas methanol resources in the surrounding areas of Ningjin to develop carbon-chemical, methanol-to-propylene and its downstream products. Under the condition that the local coal mine in Ningjin reaches a certain scale of exploitation, the second phase will consider the use of local coal resources in Ningjin to develop the coal chemical industry.
Li Zhong, director of the Resource Environment Office of the National Development and Regional Economic Research Institute of the National Development and Reform Commission, and Jia Jiaan, president of the Hebei Petroleum and Chemical Industry Association, believe that the construction of the Yancheng Coal Chemical Industry Park in Ningjin will be based on the concept of circular economy to build a material integration and energy As a basic chemical ecological cycle system, advanced clean production technologies and environmentally friendly production processes are adopted to achieve clean and harmless production.
According to another understanding, the Ningjin Yanmei Coal Chemical Industry Park covers an area of ​​approximately 20.74 square kilometers. By 2020, the total investment in the planned industrial projects and infrastructure in the park will reach 60.6 billion yuan, and the sales revenue will reach approximately 67.9 billion yuan. The annual output value is 700. Billion yuan, eventually forming a 5 million tons/year vacuum salt, 3 million tons/year soda ash, 1 million tons/year caustic soda and 500,000 tons/year methanol to olefin project as a symbol, with a variety of extended products of salt coal chemical industry Industrial clusters.
L/LL/KL/KLM/ Finned Tube Application: Mainly used in air coolers in petrochemical, electric power, paper making, tobacco, building heating and other industries, air heaters and air heaters in spray drying systems such as vegetable protein and starch in the food industry. Blast furnace and converter systems, power generation: condensate exhaust gas discharged from steam turbines, condensate contact cycle cooling condensation, fossil and nuclear power plants, air conditioners (Freon, ammonia, propane), waste incineration equipment, compressor coolers, etc.
North China's largest salt coal recycling economic park started
Hebei Xingtai Chemical Industry Association disclosed on November 30 that the salt coal chemical recycling economy park planned by Ningjin County in Xingtai City has passed the demonstration and the project has entered the implementation stage. At present, it is conducting an overall environmental impact assessment and safety planning. The project focuses on the development and extension of three industrial chains of soda ash industry, chlor-alkali industry and coal chemical industry, planning and construction to become the largest salt chemical industry base in the North China region that has reached the international advanced level.
