Product performance and standards
1, the condenser and other heat exchangers are important auxiliary equipment of thermal power plants, whether its operation is good, directly affect the economy of the power plant, its structure is reasonable mainly depends on the form of the heat exchange tube and the material of the old heat exchange tube, are made of copper, due to the strength of the material, corrosion resistance and impact resistance limitations, the wall thickness of the copper tube is 1-1.5mm, too thick the wall is not However, it affects the heat transfer effect and wastes a lot of metal materials.
Our company's stainless steel heat exchange tube is made of high-quality stainless steel pipe, cold drawing, hot drawing and strip steel, through rolling, welding, flaw detection, rolling grinding, solid melting, polishing and other one-stop production line processing; According to the actual needs of users, the production of different pipe diameters, wall thickness, length forms and other specifications of the pipe.
2, the book wall light tube produced by our company has the following advantages:
(1) Good heat transfer performance, because the tube wall can use 0.5-0.8mm thin-wall pipe, improve the overall heat transfer performance, under the same heat transfer area, the overall heat transfer coefficient is 2.124-8.408% higher than that of copper tube.
(2) Due to the use of American standards AIS1304, 316 and other high-quality stainless alloy steel, so that it has a high hardness, the steel of the pipe is also significantly improved. Therefore, it has strong impact resistance and vibration resistance to high temperature steam.
(3) Because the inner wall of the pipe is smooth, the bottom thickness of the boundary laminar flow is reduced, which not only strengthens the heat transfer, but also improves the anti-scaling performance
(4) The pipe loading process performance is good, the traditional tube expansion process is used, the outer diameter tolerance is consistent with the copper pipe, there is no need to change the processing tolerance of the tube plate hole, which is conducive to direct selection on site, especially convenient for the renewal of the old unit.
(5) Economical, under the same heat exchange area, the cost of stainless steel pipe is about 80% of the cost of copper pipe, and can be directly replaced.
(6) In order to eliminate welding stress, heat treatment is carried out at a high temperature of 1050℃ in the protective gas.
(7) All steel pipes are used for leak inspection by differential pressure method, and the pressure test is up to 1.0Mpa, with no pressure drop for 5 minutes.
