With the arrival of spring, everything recovers, the temperature gradually rises, and there will be more and more thunderstorms. As a community or building/structure manager, you should pay more attention to safety protection measures. Lightning in spring is a major hidden danger to the safety of buildings. We should carefully check and maintain every lightning protection device. As a professional lightning protection testing agency for buildings, our company takes every test seriously, so as not to leave hidden dangers, and issues a prescribed test report to pass the review quickly. Lightning protection inspection 1 test is a special operation project. Our company has a lightning protection device test qualification certificate, and the inspectors are certified to work and have a wealth of field inspection experience. Lightning protection detection is divided into lightning arrester detection and lightning protection grounding detection. Before the detection starts, the detection instrument will be debugged to ensure the accuracy of the detection data. During the inspection time, special inspection clothing and hats will be worn for personal safety protection. When inspecting a building that has been put into use, such as a certain community, we will first go to the roof of the building and check the roof lightning protection belt specifications, height, mutual distance, etc., and truthfully record and report. Our company's lightning protection detection steps: 1. Roof fans, because of the different types and brands of fans, detailed records are required. 2. The climbing ladder of the power distribution room on the roof is mostly made of metal, and the grounding resistance is relatively large, which does not exceed the standard value. 3. Equipotentiality between lightning protection belt and lightning protection belt. 4. Obstacle lights 5. Passenger elevator power distribution cabinet 6. Passenger elevator control cabinet 7. Passenger elevator machine base 8. Passenger elevator bridge frame (fire-fighting ladder power distribution cabinet, fire elevator control cabinet, fire elevator machine base, fire elevator bridge frame) 9 , Fire fighting pipeline 10, public lighting distribution box 11, power distribution cabinet, etc. If you need to sign the lightning protection inspection business for buildings or want to know more inspection procedures, you can call our company at any time. Office address: 13th Floor, Block A, Hanhai Beijin, Jinshui District, Zhengzhou City.
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.
