Jiangsu and Guangdong are the most important provinces in the export of ship equipments in the country, and the export volume of the two provinces exceeds 55% of the total export volume. From January to August, Jiangsu, Guangdong, and Shanghai ranked among the top three among the provinces, regions, and municipalities that exported ship fitting equipment. Among them, Jiangsu's exports amounted to 630 million U.S. dollars, accounting for 35% of the total export value, and the amount decreased by 4.9% year-on-year; Guangdong's export value was 382 million U.S. dollars, down 0.4% year-on-year; Shanghai's export volume was 263 million U.S. dollars, down 6 percent year-on-year. %. In addition, the export amount of Shandong Province is US$161 million. Among these four provinces and cities, Guangdong Province has the smallest year-on-year decline.
The import amount of marine diesel engines dropped by more than 30% year-on-year. From January to August, the largest amount of marine equipment imported from China was marine diesel engines, which amounted to US$771 million, accounting for 30.7% of total imports, a year-on-year decrease of 32.8%; imports of radar and navigation equipment parts amounted to US$644 million, a year-on-year increase. 12.6%; Import volume of marine propulsion and blades was US$355 million, a year-on-year decrease of 3.5%.
Asia is the most important market for China's ship equipment imports. The amount of equipment imported from North America has increased by more than 10% year-on-year. From January to August, China imported ship fitting equipment from 60 countries and regions. Among them, the largest amount imported from Asia was US$1.312 billion, accounting for 52.3% of total imports, which was a decrease of 4.5% year-on-year; the amount imported from North America was US$209 million, a year-on-year increase of 10.6%. Six countries and regions have imported more than US$100 million in the first eight months. Among them, the amount of imports from South Korea saw the largest year-on-year drop of 43%.
Shell and Tube Heat Exchanger Heat Exchanger is part of the heat transfer fluid will heat to the cold fluid equipment, also known as the heat exchanger shell and tube heat exchangers is the General Equipment in chemical, petroleum, power, food and many other industrial sectors, occupies an important position in the production of heat exchanger type is many. But, according to the principle and method of cold and thermal fluid heat exchange basically can be divided into three categories: recuperative, hybrid and regenerative. In three kinds of heat exchanger, heat exchanger is mostly used.
Recuperative heat exchanger according to different heat transfer tubes: FPR floating coil heat exchanger, LWR threaded pipe heat exchanger, WMH membrane heat exchanger. Eddy heat (heat exchange equipment promotion center)
Advantages of Shell And Tube Heat Exchanger:
1, high heat transfer coefficient: thread tube is of high efficient heat transfer component combination of internal and external thread is made of high thermal conductivity of copper or stainless steel, thread made Tube Heat Exchanger, the fluid resistance is small, then the formation of strong turbulence, which greatly improves the heat pipe inside and outside coefficient. Through the test, steam water heat when the total heat transfer coefficient is up to 3000~6000W/m2 DEG C, water water heat when the total heat transfer coefficient of 2500~5500W/m2 degrees.
2. Compact structure: This product has a large heat transfer area per unit volume, and the total heat transfer coefficient is high, so the area is greatly reduced, saving material and space
3, is not easy to scale because of the special structure of the concavo convex thread tube, the tube inside and outside effects of multi layer and rotary flow erosion, coupled with the thermal shrinkage of the extension tube, inside and outside of the tube wall will not remain impurities, so it is not easy to fouling, long running effect is good.
4, it is not easy to leak: This product is short sealing circumference, the coarse thread of the threaded pipe is similar to the expansion joint, which has the ability of compensation, the heat stress of the heat exchanger is small, and it is not easy to leak
5, easy to install: this series of heat exchangers have horizontal and vertical two types of easy to install in different locations
