“ production Acid and alkali resistant rubber hose What are the applications in engineering transformation? " In this issue, we will explain this problem for you. Those who have consulted this problem will come to see it: First, we should consider the water supply and drainage of all water related equipment, such as wells, pumps, etc., their location, installation method and temperature, including galvanized air ducts. 2、 It is very important to consider galvanized air duct in advance to avoid temporary replacement of galvanized air duct materials. 3、 After the location of the machine tool is determined, the drainage outlet can be considered to be arranged underground, which is not only convenient but also durable. 4、 After river reconstruction, there should be a suppression test, but now many construction teams do not suppress the test. It is usually said that it is not important, that there is water and pressure in the galvanized air duct, and so on. Try to be present to suppress the test. 5. If the installation is completed, pay attention to the inspection of the workshop, water pump room and FRPP drain. If the drainage system is slow, the installation program should be able to open the installation. Water outlets should be protected, especially during civil engineering construction, Acid and alkali resistant rubber hose Where can I find it? It may cause soil loss and blockage. I believe that you have a better understanding of this information, and we will continue to improve the galvanized air duct to make it more widely used.

The development trend of HVAC duct is production Acid and alkali resistant rubber hose Now more and more companies choose advanced spiral duct technology. The advantages of spiral air duct are as follows: 1. Good air tightness. Spiral air duct greatly reduces the connection of air duct and minimizes the leakage between connectors. The typical spiral air duct is 3-6m, but the typical rectangular air duct is only 1-1.5m; At the same time, only one connector is required to connect two spiral air ducts, while a typical rectangular air duct connector requires separate double flanges. 2. Standardized products. The production of spare parts (pipes and connectors) is highly automated and systematic, and has industrialized quality control. 3. Low installation cost. The installation of round duct only needs one third of that of rectangular duct. 4. Save space. Under the same pressure and the same installation space, the spiral air duct with a diameter of 200mm can replace the rectangular air duct with a diameter of 250x150mm. Without increasing the installation space, multiple spiral pipes can be used instead of wider rectangular pipes. Considering various factors, in most cases, spiral pipes require less space than rectangular pipes. Under the same pressure, the installation space of several spiral pipes is equal to or less than that of rectangular pipes. Most rectangular pipe systems require 4 bolts to fix, which will increase 40~80mm in each direction. 5. The pressure drop is low. As we know, spiral duct has lower ventilation resistance than rectangular duct. 6. Precision locking technology. Chengdu Acid and alkali resistant rubber hose The mold on the is made of special steel. After years of use, the surface remains unchanged, making the surface of the spiral air duct free of scratches and extending the service life. 7. The perimeter of rectangular air duct with length width ratio of 1:3 at the same section is 40% larger than that of spiral air duct, which means that spiral air duct saves more materials and reduces thermal insulation.

Chengdu Acid and alkali resistant rubber hose With the continuous updating of technology, the products are also developing in the continuous updating. At present, the inspection requirements of rubber hose are also improved compared with the previous ones. The inspection index of ultra-high pressure hose shall meet the following index requirements according to the requirements of the Safety Code for High Pressure Water Jet Cleaning Operation: 1) The bursting pressure shall be more than 2.5 times of the working pressure. 2) The test pressure shall be 1.5 times of the working pressure, and the pressure shall be kept for more than 2 minutes without damage. 3) Pulse pressure shall be within the range from zero to working pressure, and 50000 pressure pulses shall be free of damage; The pulse frequency is 15 times/min when the working pressure is 1000-2800bar, and 110 times/min when the pressure is above 2800bar. Since high-pressure cleaning machine has been widely used in all walks of life, and the working condition of high-pressure hose is relatively the worst, we must pay attention to the quality when selecting high-pressure hose, so as to avoid unnecessary safety accidents. Acid and alkali resistant rubber hose Where can I find it? The development of rubber hose can not be separated from cooperation, R&D and innovation can not be separated from communication, and the inspection requirements of rubber hose have been improved compared with the previous ones. The storage site shall be free of ozone, heat source and equipment generating electromagnetic field. The coiled hoses or hose assemblies shall be stored horizontally, and the stacking height shall be limited to the extent that the products at the bottom will not produce permanent deformation.

Now on the market Chengdu Acid and alkali resistant rubber hose There are various models of galvanized air ducts. I believe you are familiar with galvanized air ducts. Do you know the main characteristics of galvanized air ducts? If you don't know, you can have a look. It will be helpful to purchase and use galvanized air ducts in the future. Galvanized air ducts refer to air supply, exhaust and smoke exhaust ducts used in hotels, shopping malls, textiles, chemical fiber, petrochemical, machinery manufacturing, instruments, electronics, medicine, tobacco, food, medical care, storage, office buildings, subway, civil air defense, basement and other projects. Its thickness and specification can vary according to requirements. Generally, when connecting, both ends of the galvanized spiral air duct are always externally connected to the accessories. Galvanized air duct metal air duct is made of various metal materials, commonly including galvanized iron sheet and stainless steel. With the continuous development of the tank industry at present, more and more industries and enterprises have applied to the tank industry, and more and more enterprises have entered the tank industry. Composite air ducts are composed of various inorganic materials, which can be divided into various types according to their composition, but most of them are lightweight, porous, and have large thermal resistance. First of all, the galvanized air duct is exquisite, compact, durable, beautiful, noble and elegant. The support and hanger of iron sheet air duct should be in the form and specification suitable for strength and rigidity according to the national standard atlas and specifications. The supports and hangers of extra wide, overweight and other special iron sheet air ducts with diameter or side length greater than 2500 mm shall be in accordance with the design regulations. Acid and alkali resistant rubber hose Where can I find it? High quality galvanized sheet is used. Condensate water pan is molded by molding process. There are no welding seams, welding spots, and thermal insulation materials (applied to industry and buildings) that meet the fire protection standards are connected to the water pan as a whole. The galvanized air duct is small in size, and the installation of drainage pipes and lines is simple and convenient. The left and right connecting pipes and return air modes can be changed at any time to match the site conditions. Galvanized air duct can be installed in any space.
