As the use time increases, production Oxygen band A large amount of impurities will accumulate in the pipeline. These impurities stored in the pipeline for a long time will accelerate the condensation of oil, form pneumatic valves, damage hydraulic components, and have a great impact on normal operation. Therefore, it is very important to clean the stainless steel welded air duct regularly. How to clean impurities in stainless steel welded air duct? When the stainless steel welded air duct is connected with the fan, the inlet and outlet shall be provided with flexible joints. The size of flexible joint shall be the same as the inlet and outlet of fan. Hose joints are usually made of canvas, artificial leather and other materials. The hose length shall not be less than 200. Sealing shall be proper. Hoses dampen fan vibration. Before the welding air duct is connected with the dust removal equipment and heating equipment, and after the completion of the equipment, the prefabrication and equipment shall be stopped according to the theoretical mapping. During equipment installation, the inlet and outlet of stainless steel welded air duct shall be opened during prefabrication. If an air outlet is required at the end of the pipe, the connection shall be closed. When transporting natural gas containing condensate or water, the horizontal pipeline shall be inclined, and the drainage pipe shall be connected at the low point. Longitudinal joints do not apply to the bottom of the pipe. Sealing treatment shall be stopped for the bottom joint. For steel plate air ducts conveying flammable and explosive gases, cross connectors shall be installed at the connecting flanges of the air ducts and connected to the electrostatic grounding grid. When the height of the horizontal airway is more than 4m, the installation personnel shall fasten the safety belt. Oxygen band Where can I find it? The springboard on the scaffold or movable support shall be fixed. The width of the springboard shall meet the safety specifications. The installation personnel on the scaffold shall carry bags with them to prevent falling objects or electric drills from hurting people. After installing double hangers on the welded air duct, the cross arm shall be straight and the suspender shall not be replaced.

“ production Oxygen band 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, Oxygen band 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.

Zaozhuang Oxygen band 1. The manufacturing quality shall be guaranteed according to the national standards of Oxygen Hose (GB/T2550-91) and Acetylene Hose (GB/T2551-91) respectively, and the hose shall have sufficient compressive strength and flame retardant characteristics. According to the national standard, the oxygen hose is red, the working pressure vessel is 1.5MPa, the inner diameter of the hose is 8mm, and the outer diameter is 18mm; 2. Care must be taken when storing and using the hose to keep it clean and free from damage. For example, avoid exposure to sunlight, rain and snow, and prevent contact with substances such as acid, alkali, oil and other organic solvents that can damage the hose. The storage temperature shall be - 15 ℃~40 ℃, and the distance from the personnel shall not be less than 1m; 3. When using a new hose, the talcum powder on the inner wall of the hose must be blown out first to prevent the channel of the welding torch from being blocked. Avoid external extrusion and mechanical damage during use, and do not fold the pipe body. 4. If the oxygen hose catches fire, stop the air supply first, and then deal with the fire hose, but do not bend the hose. The cylinder valve must be closed when the cylinder is not in use or after work. 5. The hose with bulge, crack or air leakage shall not be used, and the air leakage hose shall not be used after being stuck with adhesive tape. Oxygen band Where can I find it? When connecting the two ends of the hose with tools, clamp or wire shall be used to fasten, and the intermediate joint shall be fastened with a gas pipe connector.

Zaozhuang Oxygen band The structure is composed of liquid resistant synthetic rubber inner rubber layer, medium rubber layer, I or II or III steel wire braid reinforcement layer, and weather resistant synthetic rubber outer rubber layer.
