The consumption of galvanized iron sheet air duct in China's chemical industry also shows a rapid growth trend. The rapid increase in the consumption of galvanized iron sheet air duct in China's chemical industry has stimulated domestic Oil hose Where can I find it? With the rapid development of industry and the support of relevant government policies, in a short period of time, the production of galvanized iron air ducts in China has been developing rapidly. From the perspective of industrial chain, galvanized iron duct and upstream and downstream products enterprises of galvanized iron duct are interdependent and competing industries. Steel production enterprises can establish long-term and stable strategic alliances with downstream enterprises through deep processing of steel products, which is conducive to promoting the development of new varieties, quality improvement and market expansion of galvanized iron sheet air duct industry, and is an effective way to extend the value of steel products to the downstream and improve the competitiveness of the product market. It can be said that the development of high-quality galvanized iron duct projects has become a development strategy for Chinese galvanized iron duct manufacturers to cope with fierce market competition and improve product competitiveness. At present, in the consumption structure of galvanized iron duct in China, except for some high-end products that still rely on imports, middle and low-end products can basically achieve self-sufficiency. The situation that galvanized iron duct consumption completely depends on imports has been greatly improved, and the export volume is also expanding rapidly. However, compared with the developed areas of galvanized iron duct industry, China's galvanized iron duct industry system is not perfect, and there is still a big gap compared with Japan, South Korea and other large stainless steel reactor production countries. The development of galvanized iron sheet air duct industry in China started late, and the social demand for stainless steel reaction kettle grew too fast, which led to high quality Oil hose The first problem to be solved for industrial development is to rapidly increase output to meet the growing social demand, gradually replace imports, and complete the two steps of "quantitative change" and "qualitative change". At present, the development of galvanized iron duct industry in China has completed the accumulation process of "quantitative change", and is currently facing the transformation of "quality".
What is stainless steel spiral duct? Oil hose Where can I find it? The products are mainly used to connect the air flow between two places and play the role of ventilation. There are three types of galvanized spiral air ducts, stainless steel spiral air ducts and composite spiral air ducts. Here we mainly talk about the stainless steel spiral air duct, and briefly analyze the reason why it is widely used in villas. The so-called stainless steel air duct is strictly a kind of air duct processing technology, also known as spiral seamed thin-walled tube. The best quality is the thin-walled tube with spiral seamed made of metal strips. Because the applied material is metal, it is also called spiral seamed metal tube. It was first used in the military industry of western countries, such as ships, ship ventilation, air conditioning systems, and later used in trains Subway, mine and other civil facilities. By 2000, according to statistics, 95.6% of office buildings, shopping malls and subways in the United States had applied spiral air ducts. In civil residential buildings, 72.5% of central air conditioners use spiral air ducts. Since the mid-1990s, China has introduced this technology into the shipbuilding industry. With the rapid development of China's economy, the use of central air conditioners has increased year by year, and the quality of auxiliary products for exhaust and air supply has been continuously improved. Spiral air ducts have been widely used in some villas. (1) Product standardization: The production of spiral round air duct fittings (pipe fittings and joints) has been highly automated, systematic, and has industrialized quality control. It is well known that the wind resistance of circular duct is much smaller than that of rectangular duct. (2) Easy to install. The installation of spiral air duct significantly reduces the connection points between pipes and minimizes the leakage at the joint of pipe fittings. The typical spiral air duct is 3~6m long, while the typical rectangular air duct is only 1~1.5m long; The connection of two spiral air ducts requires only one pipe connector, while the connection of traditional rectangular air ducts often requires a completely independent double flange system. (3) Usually only small installation space is required: the same high quality Oil hose The circular pipe with a diameter of 200mm in the installation space can replace 250 × 150mm rectangular pipe. On the premise of not increasing additional installation space, several parallel circular pipes can replace flat rectangular pipes.
high quality Oil hose 1. During the molding of rubber products, the cohesive force of the elastomer cannot be eliminated due to the large pressure pressing. During the molding and mold release, extremely unstable shrinkage (the shrinkage rate of rubber varies due to different rubber types) often occurs. It must take a period of time before it can be gentle and stable. Therefore, at the beginning of the design of a rubber product, no matter the formula or the mold, it is necessary to carefully calculate the matching. If not, it is easy to cause dimensional instability of the product, resulting in low product quality. 2. Rubber belongs to thermosetting elastomer, while plastic belongs to thermosetting elastomer. Due to different sulfide types, the temperature range of rubber molding and curing is quite different, even affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be properly adjusted at any time. If not, there may be differences in product quality. 3. The rubber product is the rubber mixture made from rubber raw materials after mixing in the internal mixer as the raw material. The formula is designed according to the characteristics of the required rubber products during mixing, and the required product hardness is determined. The product is molded by the rubber plate vulcanizer. After the product is formed, flash processing shall be carried out to make the product surface smooth without burrs. 4. The aging test of rubber products belongs to the category of aging test. Rubber aging refers to the phenomenon that the performance and structure of rubber and products are changed due to the combined effect of internal and external factors in the process of processing, storage and use, thus losing their use value. Oil hose Where can I find it? It is characterized by cracking, tackiness, hardening, softening, chalking, discoloration, mildew, etc. The following conditions shall be met when the ball mill uses the rubber lining plate: 1. The hardness of the ground material. The iron base alloy is similar to the rubber lining plate for materials below medium hardness, and the rubber lining plate is superior for materials above medium hardness. 2. The temperature of rubber lining plate is generally 70 ℃ - 90 ℃, and it can reach 110-130 ℃ under special circumstances. The temperature should be lower during dry grinding. 3. Feed size. Generally, the ball mill shall be more than 20-25mm; For the autogenous mill, the feeding particle size can be larger because no steel ball is added.
People buy in daily life high quality Oil 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. Oil 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.
Yinchuan Oil 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. Oil 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.
How to install correctly Yinchuan Oil 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 Oil 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.
