How to install correctly Yunnan Acid and alkali resistant rubber hose ？ In the fire smoke exhaust pipe system, the airport and air valve must use non fuel, and the thickness of citizen flue and galvanized ventilation pipe should be improperly used. The high-pressure system should be selected according to the national code GB50243. When the fire smoke exhaust fan is installed on the roof, certain maintenance measures should be taken. The exposed power line must be threaded through the conduit, and the conduit material should be combined with the metal hose or Capelli and duck neck equipment to make it curved. The fire fighting system and equipment lines must be fixed with special clamps to avoid falling. Stainless steel air duct and ventilation equipment shall be made of three fabric flame retardant materials with soft connection. It is suggested that the length should be 15-30cm, and the electrical interpenetration should be completed. Bolts require the same length. The three main bodies should be grounded, ventilation equipment, and equipment and devices between dynamic loads should be equipped with shock absorption measures. When Acid and alkali resistant rubber hose Where can I find it? Box type pipe fittings should not be used for changing direction, variable diameter, branch road, or junction, but the wind speed of box section should not exceed 1.5m/s for air distribution and static pressure box when necessary; It is advisable to have 5-10 times the pipe diameter between conduit pipes. The length of expandable metal pipes or non-metallic soft links should not exceed 2 meters. There should be no disintegration and dead corners. During the installation process, when the length of pipe elbows and straight pipes exceeds 20 meters, add anti impact frame open room exhaust fans and add or subtract supports.

Acid and alkali resistant rubber hose Where can I find it? Precautions ① The acid and alkali resistant rubber hose used shall not only be oil resistant, but also be pressure resistant, heat resistant, cold resistant, wear resistant and aging resistant. ② The rubber hose should not be too long or too short, generally 1.4 meters. ③ The interface is tight and can be fastened with thin iron wire or clip to prevent falling off and air leakage. ④ It is forbidden to pull acid and alkali resistant rubber hose from one room to another or through walls, floors and floors to prevent accidents caused by rubber hose breaking and falling off. ⑤) The acid and alkali resistant rubber hose should be placed in a place where it can be seen frequently, so that it is easy to detect leakage. Check whether the rubber hose leaks after each bottle change. ⑥ Do not replace acid and alkali resistant rubber hose with universal rubber hose. Since the full rubber hose does not contain a skeleton layer, it is only necessary to use a press out machine to press out the hose; The cloth clamping hose needs to use a molding machine that wraps the adhesive tape on the inner adhesive layer; When forming the suction hose, first wrap the metal spiral wire and then wrap the inner rubber; Special fabric knitting machine or winding machine shall be used for knitting and winding hose; Knitting machine is required for knitting hose. Yunnan Acid and alkali resistant rubber hose The basic production processes include rubber mix processing, cord fabric and canvas processing, rubber tube molding, vulcanization, etc. The manufacturer of acid and alkali resistant rubber hose said that the processing method of the skeleton layer and the forming equipment of the rubber hose are different for different structures and different skeletons.

People buy in daily life production Acid and alkali resistant rubber hose Take it home for installation. It is obviously installed very well, but the spiral air duct will become loose for a long time, which gives most users a headache. So what is the problem with spiral air duct reinforcement? This is of course necessary. The following manufacturer of galvanized spiral air duct will give you a detailed introduction. 1. Reinforcement measures shall be taken for circular pipes (excluding spiral pipes) with a diameter greater than or equal to 80 mm, a section length greater than 1250 mm or a total area greater than 4 ㎡; 2. The side length of rectangular air duct is more than 630 mm, the length of pipeline insulation side is more than 800 mm, the section length is more than 1250 mm, or the plane area of one side of low pressure pipeline is more than 1.2 m2, and that of medium and high pressure pipeline is more than 1.0 m2, so reinforcement measures should be taken; 3. For reinforcement of irregular oval pipes, the reinforcement method of rectangular pipes shall be referred to. The spiral air duct manufacturer Hongyuansheng Electromechanical also has something to say: the reinforcement of galvanized air duct non-metallic air duct should also meet the following requirements: when the diameter or side length of the rigid PVC pipe is greater than 500 mm, the connection between the pipe and the flange should be equipped with stiffening plates, and the spacing should not be greater than 450 mm. The reinforcement of organic and inorganic FRP pipes shall be made of the same materials with the same anti-corrosion performance as the pipes themselves. Acid and alkali resistant rubber hose Where can I find it? The manufacture of rectangular pipe elbows shall generally adopt concentric arc elbows with the curvature radius of the length inside and outside the plane. When other forms of elbow are used, and the plane length is more than 500 mm, the elbow deflector shall be set.

production Acid and alkali resistant rubber hose 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 Acid and alkali resistant rubber hose 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.

production Acid and alkali resistant rubber hose The manufacturing of is highly automated and the production speed is very fast. The general air duct can produce 20~40 meters per minute. Due to the low price of its raw material galvanized strip steel compared with the whole galvanized steel sheet, and its factory production and specification standardization, the cost of spiral air duct is lower than that of rectangular air duct; In addition, the total cost of spiral air duct is low due to the less demand for supports and hangers and the less installation work. Since the four corners of rectangular air ducts are prone to turbulence, reducing the effective flow area, the spiral air ducts have good air fluidity and large effective flow area, so the secondary noise of spiral air ducts is low. Because the spiral air ducts are strong, the low-frequency noise caused by air duct vibration is smaller, the air flow performance is good, the system pressure drop is small, and the daily operation system consumes less power. Spiral air ducts in the market are generally divided into three categories according to their materials: galvanized spiral air ducts, stainless steel spiral air ducts and composite spiral air ducts. Among them, spiral air duct has the best quality and strong applicability, but its price is high. At present, the most widely circulated spiral air duct on the market is galvanized sheet. The galvanized sheet spiral air duct is basically the characteristic of stainless steel spiral air duct, but its price is only two thirds or even lower than that of spiral air duct. Yunnan Acid and alkali resistant rubber hose It is generally used in places where the external environment is relatively common and the requirements for air ducts are not too high. As the iron sheet is prone to chemical reaction in various environments, corrosion and rust will occur. However, zinc hardly changes in dry air. In humid air, dense basic zinc carbonate film will be formed on the surface of zinc. The spiral air duct is mainly coated with zinc on the iron sheet of the air duct to protect the iron sheet. The protective and decorative properties of zinc coating can be significantly improved after passivation treatment, dyeing or coating with light protecting agent.
