Anti-corrosion Spiral Steel Pipe Combination Analysis

The spiral tube heat exchanger according to the ssaw steel pipe structure has the advantages of strong structure, strong adaptability, wide selection of materials, easy manufacture, low production cost, etc., and is widely used in refrigeration and air conditioning, chemical, pharmaceutical and other industries.

The control of the steam parameters of the medium-pressure parameter boiler mostly uses the surface desuperheater. Because the original design of the casing surface desuperheater has a limited temperature regulation range, maintaining the superheated steam temperature often becomes a limiting factor for the change of boiler fuel and the operation mode. In order to increase the temperature adjustment range of the surface desuperheater, Harbin Xinfuhua Combustion Engineering Co., Ltd. designed the FH type spiral tube desuperheater, also known as the coiled tube desuperheater, so that it can be well desuperheated.

PVC-C single-wall spiral tube not only has high quality such as higher flame retardancy, higher Vicat temperature, higher volume resistivity, higher strength and smaller friction coefficient. At the same time, it also has the functions of bending and coiling, which not only greatly facilitates storage, transportation, stacking and construction. Also due to the greatly reduced number of joints: lkm straight pipe joints are 166, while PVC-C spiral pipe joints only 10. It not only saves inspection and joint costs, but also greatly improves the safety and reliability of buried power pipes in Hebei large diameter spiral steel pipe manufacturers. Moreover, the unit of the pipe is light in weight and convenient in construction, so the overall cost is not high.

Supercritical boilers have outstanding characteristics such as high technology content, good economic efficiency, low resource consumption and less environmental pollution. The difficulty in the manufacture of supercritical boiler water wall is mainly concentrated in the middle of the water wall, and the middle screen of the side wall is the key of the large water spiral spiral steel pipe manufacturer in the whole water wall system. It is a spiral tube screen made by the principle of a spiral tube. 16mn spiral steel pipe. According to its nature, it is made of HDPE plastic spiral tube, which has the advantages of light texture, high strength, good toughness, easy laying, small water resistance, low cost and corrosion resistance. Its performance and economic benefits far exceed reinforced concrete pipes and ordinary seamless steel pipe.

In the heat transfer design of metallurgy, petrochemical and other industries, there are many forms of heat exchangers, but the conventional heat exchangers have many disadvantages such as poor heat exchange effect, difficulty in cleaning, and large thermal resistance of dirt, which cannot be satisfied. Production needs of customers. The spiral tube heat exchanger according to the spiral tube throat has the advantages of good heat exchange effect, easy cleaning, small heat resistance of dirt and compact structure.

The plastic spiral tube (also known as the hollow wall wrapped plastic tube) is a plastic tube with a very reasonable wall structure. The whole structure adopts a spiral structure. In the urban drainage project, it can improve the drainage capacity of the facility (or reduce the pipe diameter) and the service life of the project, facilitate construction, shorten the construction period, and when the groundwater level is high, the buried depth is large, or the excavation and repair of high-grade pavement is required, the project cost Significantly lower.
