one Baoji Peristaltic pump pipe When using, the talcum powder on the inner wall of the hose must be blown clean 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. 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 acids, alkalis, oils and other organic solvents that can damage the hose. The storage temperature shall be - 15~40 ℃, and the distance from the heat source shall not be less than 1m. 3. According to the national standards, 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; The acetylene hose is black, the working pressure vessel is 0.3MPa, the inner diameter of the hose is 8mm, and the outer diameter is 16mm. 4. The gas cutting operation requires a large oxygen output, so the valves of the gas cylinder (or oxygen pipeline) connected to the high pressure end of the oxygen meter should be fully opened to ensure adequate flow and stable pressure. The low pressure gauge has indicated the working pressure, but the pressure drops suddenly when using oxygen. At this time, it is easy to backfire and may backfire into the oxygen hose to cause explosion. 5. Oxygen hose and acetylene hose shall not be mixed or substituted with each other, and oxygen and hose shall not be used to blow away the blockage of acetylene hose. At the same time, it is necessary to check and eliminate the defects such as gas leakage and blockage of the welding torch at any time to prevent the formation of oxygen and acetylene mixture in the hose. It should be pointed out that the hose color specified in the national standard is opposite to that specified in the international standard (ISO) (oxygen hose is black, acetylene hose is red). At the same time, it is different from the original ministerial standard (HG4-605-66) that oxygen hose is red and acetylene hose is green. Before 1966, domestic oxygen hose was black or green and acetylene hose was red. thus Peristaltic pump pipe Where can I find it? It causes inconsistency between the understanding and habits of the supply department and the user, and is easy to cause accidents due to the mixing and substitution of rubber hoses. At present, it should be emphasized that unified understanding and use should be carried out in accordance with the provisions of national standards, and attention should be paid to distinguishing the rubber hoses of imported equipment.

Baoji high quality In places that must be crossed or may rub with the mechanical surface when working, hose clamps or springs and other protective devices should be used to prevent the outer layer of the sandblasting hose from being damaged. Sand blasting hose shall be arranged to avoid heat source as far as possible and away from the performance of engine exhaust pipe. If necessary, sleeve or protective screen can be used to prevent the hose from being heated and deteriorated. When the sand blasting hose must be bent, the bending radius should not be too small, and should be greater than 9 times the outer diameter. There should be a straight line section greater than 2 times the outer diameter of the pipe at the joint between the rubber hose and the joint. How high-quality the products and equipment we use are, it is inevitable that there will be some large and small failures in the process of using them, which will more or less have a certain impact on our work. Just like the use of sandblasting hose, there are traces of its outer adhesive seam, problems must be solved, For this, we explained the following solutions: First, the used water cloth should be used according to the original elastic edge of the water cloth when it is reused. 2： When we wrap the water cloth around the seam of the sandblasting hose, we should apply sufficient and uniform pressure to the pipe body. 3. The water cloth with different widths should be selected according to the size of the outer diameter of the wrapped sandblasting hose (for hose with an outer diameter of less than 30mm, the width of the water cloth should not exceed 90mm). The overlapping width of the water cloth should be 3/5-2/3 of the width of the water cloth.

Now on the market Baoji Peristaltic pump pipe 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. Peristaltic pump pipe 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.

high quality Peristaltic pump pipe The inner and outer walls are smooth, the resistance of the air duct is small, the secondary noise is not generated during air supply and exhaust, the energy consumption is reduced, and the operation cost is saved. The product can be made on site, cut, drilled, and opened, the installation is simple, and the labor and time are saved. The user's investment cost is reduced, the construction period is shortened, the performance price ratio is high, and it is cheaper than other materials. After the installation is completed, no maintenance is required, and the maintenance cost is reduced. The key points of whether galvanized sheet air duct material galvanized sheet is corroded are mainly reflected in the following three aspects: ① The first corrosion of galvanized sheet in the entire service life cycle is the oxidation of the galvanized layer on the surface, resulting in white rust. After a little longer time, the white rust on the surface further reacts with carbon dioxide and other impurities in the humid air to form black spots. When the galvanized sheet is used for a long time and the galvanized layer is severely corroded, the steel base loses the sacrificial anti-corrosion effect of zinc, and begins to oxidize to generate red rust. Once the steel base begins to oxidize, the corrosion rate becomes very fast, and the life of galvanized sheet ends. ② In addition, there are two special corrosion conditions of galvanized sheet, namely, black stain. One is that after being used for a period of time, due to the influence of lead and other elements in the zinc coating, the galvanized sheet will become black in the matte part of the zinc flake. The blackened zinc coating still has a protective effect on the steel base, but has a certain impact on the service life. ③ Peristaltic pump pipe Where can I find it? It has excellent corrosion resistance in dry or pollution-free environment. However, in the polluted environment, the service life will be greatly shortened, so it is necessary to pre coat the film into color plates before use.

The development trend of HVAC duct is high quality Peristaltic pump pipe 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. Baoji Peristaltic pump pipe 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.
