The finned tube is to improve the heat exchange efficiency. By adding fins on the surface of the heat exchange tube, the outer surface area (or inner surface area) of the heat exchange tube is increased, so as to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube . Usually used for heat exchange between liquid and gas.
Finned tube is a heat exchange element. As a heat exchange element, finned tubes usually work under high-temperature flue gas conditions for a long time. For example, the finned tubes usually used in boiler or harsh environments, high temperature and high pressure, and in a corrosive atmosphere. This requires that the finned tubes should have high anti-corrosion properties, Anti-wear properties, lower contact resistance, higher Stability and anti-dusting ability.
There are many types of finned tubes, and new varieties are constantly emerging. According to the classification of processing technology, there are extruded fin tube; high frequency welded finned tubes; rolled formed finned tubes; suit formed finned tubes ; cast finned tubes; tension wound finned tubes; Inserted tubes.
According to the shape of the fins, there are square finned tubes; circular finned tubes; spiral finned tubes; longitudinal finned tubes; corrugated finned tubes; spiral serrated fins Helical Serrated Finned Tubes; pin-shaped finned tubes; integral plate-shaped finned tubes; inner finned tubes.
According to whether the fin material of the finned tube is the same as that of the base tube, it can be divided into: single metal finned tube, bimetallic composite finned tube.
Single metal finned tubes are classified by material into copper finned tubes; aluminum finned tubes; carbon steel finned tubes; stainless steel finned tubes; cast steel finned tubes.

In the cold prevention work, based on the revision and improvement of the “Winter Production Planâ€, the plant launched a proposal for the production of key stakeholders, based on the winter cold weather experience and the actual situation this year, the various pipelines and wells, valves and other winter inspection route The patrol content will be detailed and clear, and the responsible person will be implemented.
At the same time, the plant comprehensively inspected the use of guide pipes and steam traps in the steam pipe network, installed direct discharge pipes and water distributors at seven drainage points, and digged the seepage wells, completing 23 steam pipe network insulation. For the groundwater pipe network, due to the leakage of partial pipelines and individual valves for many years, the plant organized the manpower to reform the pipe network. For the heating pump station and the condensate recovery pump station, a unified arrangement of equipment trials and cold transport test leaks eliminates indoor and outdoor leaks and 10 types of hidden dangers, ensuring the normal operation of the heating system.
