A finned tube is a heat transfer device consisting of many parallel metal fins commonly used for heat dissipation and cooling applications. Finned tubes increase the surface area of the pipe, thus increasing the heat transfer efficiency. Finned tubes are commonly used in applications such as air coolers, automotive radiators, condensers, and evaporators. They are also used in industrial heaters and refrigerators to increase heat transfer surface area and improve efficiency.
Finned tube is a kind of new, wear-resistant, efficient heat exchange material, is a kind of energy-saving heat exchange element, it uses high-frequency power source as heat source, the steel strip, steel pipe heating at the same time, so that the fusion welding together into one, with high heat exchange efficiency, large cooling area, long service life, adapt to a wide range of temperature, high pressure characteristics, it can also be made of a variety of materials, Excellent heat transfer, durability, heat resistance and corrosion resistance. Widely used in waste heat recovery, petrochemical, power plant boiler, economizer, bus, industrial and civil construction heating, refrigeration, medical drying, wood drying, food drying system and other industries.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.

The notice pointed out that at present, the national economy continues to maintain a generally stable and good running situation, and the coal and electricity and gas supply and demand are basically balanced. However, due to factors such as rapid growth in domestic demand and continued rising prices in the international market, the supply of coal, diesel, and electricity in some regions has experienced varying degrees of tension. Fertilizer prices continue to rise at high levels and continue to rise. huge pressure. The notice requires that the current coal and gas oil and gas transportation guarantees and agricultural resources supply work be carried out effectively to ensure the agricultural harvest, the restoration and reconstruction of the disaster-stricken areas, and the sound and rapid economic and social development.
The notice required Guizhou, Shaanxi, Ningxia and other places to organize the support of the coal resources in the affected areas. The railway and transportation departments should arrange good transport capacity and continue to guarantee the need for electric coal in the affected areas. The disaster-stricken areas should speed up the recovery of local coal production on the premise of ensuring production safety.
The notice required CNPC and Sinopec to organize an increase in the supply of refined oil in the disaster-hit areas and continue to ensure the need for oil products in the affected areas. The State Grid Corporation of China shall reduce the transmission of electricity from Sichuan and transmit electricity to Sichuan as required to ensure disaster relief and recovery of electricity for use in the affected areas. State Grid Corporation of China and Sichuan Local Power Grid Corporation shall continue to do a good job in repairing and recovering damaged power facilities, restore important users and residents as soon as possible, and strive to complete the repair of damaged equipment in the main power grid and distribution network in Sichuan by June 10. And transformation to restore normal power supply in the disaster area.
The circular emphasized that all coal-producing provinces must work hard to increase coal production under the premise of ensuring safety, and accelerate the suspension of production to rectify the acceptance of the resumption of production of small coal mines. Coal-producing counties that plan to discontinue production of more than one-third of their capacity must be approved by the provincial government and reported to the National Development and Reform Commission and the State Administration of Safety Supervision for the record.
The notice requires thermal power enterprises to organize the purchase and storage of coal for electricity, and strive to keep coal inventory at least 15 days; related oil companies must effectively balance the total amount of refined oil resources and the coordination of production, transportation and sales. PetroChina and Sinopec should try every means to ensure agriculture. “Sanxia†uses oil and arranges emergency preparations for the “three summers†using the nearest company in advance.
The notice pointed out that all regions and relevant departments should implement various preferential policies for supporting and promoting the production, supply and circulation of fertilizers and other agricultural materials, organize the production and transportation of agricultural materials, and ensure the market supply of fertilizers and other agricultural materials. At the same time, guide farmers to scientifically apply fertilizers, increase organic fertilizers, and increase fertilizer utilization.
The circular also requires all localities and relevant departments to continue to adjust the industrial structure, increase the access threshold for high-energy-consuming industries, resolutely eliminate backward production capacity, and promote energy conservation.
The General Office of the State Council recently issued a circular demanding that provinces, municipalities, autonomous regions, and all ministries and commissions of the State Council and all directly affiliated institutions shall fully guarantee the coal and electricity and hydrocarbon transportation needs of the disaster-hit areas, fully do a good job in peak summer work, do a good job in the refined oil market, and do everything possible to ensure agriculture. “Sanxia†uses oil and effectively guarantees the market supply of fertilizers and other agricultural resources.
