According to different insertion methods and different insertion angles, the plug-in steel grating can be divided into pressed steel grating, heavy steel grating, integral steel grating, sunshade steel grating, etc. Plug-in steel grating. After the bearing flat steel is grooved, the cross bar flat steel is press-locked and formed. Generally speaking, the maximum processing height for the production of ordinary steel grating is 100 mm. The length of the steel grating is usually less than 2000mm. The heavy-duty plug-in steel grating is a steel grating product in which the high flat steel and the horizontal bar flat steel are interlocked and pressed under a pressure of 1200 tons. Suitable for large-span load-bearing occasions:
(1) Evaporation and concentration of circulating cooling water during circulation. The salt concentration in the water gradually increases. On the other hand, some salts are deposited due to exceeding the saturation concentration, causing fouling of the components.
(2) The loss of CO caused by sprinkler water in the cooling tower exacerbated the CaCO in the water. precipitation. At the same time, the increase of O2 in the water contributes to the corrosivity of the water.
(3) Various impurities in the atmosphere (such as dust, suspended solids, etc.) and oil leakage and peeling from cooling tower fans will also enter the water.
(4) After chemicals are added in the process, the cooling water will produce sediment (5) The reproduction of microorganisms in the system and their secretions will form sticky dirt. The use of steel grating makes the entire steel structure platform like a flat ground, which greatly enhances the safety of construction operations. In the later production process, the use of steel grating is more convenient for daily work.
The permeability of the steel grating makes the work guidance more intuitive and convenient. And the daily maintenance of the steel grating is basically maintenance-free, which greatly saves the maintenance cost of the chemical plant. The production cycle of steel grating is short, the supply speed is fast, the construction time of traditional platform is shortened by 90%, the installation is simple and fast, and the construction of steel structure is convenient.
