Yangzhou Sandblasting hose The entry threshold is low, the industry market is mixed, and small enterprises with small scale, lack of core competitiveness and low technical level can be seen everywhere. Most of these enterprises lack brand awareness, and there are many brand names and unlicensed products. It is difficult to form enterprise influence through brands, and it is more difficult to improve product added value through brands. If the metal hose wants to take the road of high-end, it must improve both inside and outside. A good brand image promotion and influence building can certainly provide a strong driving force for the development of enterprises, but the root of this driving force lies in the high quality of the metal hose products themselves. Tongfeng Metal Hose said that in the future, domestic metal hose products will focus on high precision, high efficiency, high firmness, multi-function, multi specification, multi variety standardization, serialization and generalization to show their characteristics. One of the main reasons why China's metal hoses have been in the low-end state for a long time is the lack of independent research and development of products. On the one hand, the homogenization competition is serious. In order to win consumers, metal hose enterprises have long focused on low-cost competition and low price shopping. As a result, many enterprises only focus on the production and marketing of low-end products, ignoring the upgrading and innovation of product technology. on the other hand, Sandblasting hose company ZHUANLI's weak awareness of protection and the serious phenomenon of technology plagiarism and infringement in the industry make the technology cost invested by many enterprises more than worth the cost, which has seriously hit the enthusiasm of metal hose enterprises for innovation.

The spiral air duct will certainly be affected in the low temperature environment, so how should our manufacturer deal with this situation? First Sandblasting hose company Do a good job in thermal insulation and select thermal insulation materials (applicable to industry and construction industry), but the selection of thermal insulation materials (applicable to industry and construction industry) is also necessary. Shandong Hongyuansheng, a spiral air duct manufacturer, will tell you how to choose. Good thermal insulation performance. The specification of the next thermal insulation material (applicable to industry and buildings) should meet the requirements of the air duct system used, not only that, but also the design requirements of the air duct. The thermal insulation material (applicable to industry and buildings) has product quality certificates and other qualified documents. Galvanized spiral air duct is widely circulated in the municipal spiral air duct market. The galvanized steel plate spiral air duct is basically the feature of stainless steel spiral air duct, but its price is only two thirds or even lower than that of stainless steel air duct. Composite spiral air duct is generally used in the environment where the environment is common, and the requirements for air duct are not too high. Thermal insulation materials (used in industry and construction) can effectively protect pipelines from damage in winter. Galvanized spiral air duct is widely circulated in the spiral air duct market. The galvanized steel plate spiral air duct is basically the feature of stainless steel spiral air duct, but its price is only two thirds or even lower than that of stainless steel air duct. Yangzhou Sandblasting hose It is generally used in the environment where the environment is common, and the requirements for air ducts are not too high. In terms of clean air ducts, fire-resistant closed cell rubber foam insulation materials (used in industry and buildings) are generally used, and incombustible aluminum (aluminum) foil glass wool board is used for smoke exhaust ducts. These two materials are common and have good thermal insulation performance.

wear-resisting Sandblasting 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. Yangzhou Sandblasting 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.

The air conditioning in the hall of a giant building is provided by the 6FWB unit fixed in the basement. wear-resisting Sandblasting hose The vibration of the unit is transmitted to the ground hall through the bridge connecting the sand blasting hose pipe, and the noise value reaches 45dB. In such an environment, people always feel uncomfortable. After the improved design, sandblasting rubber pipes were connected in series on the connecting pipes, which not only absorbed some of the noise generated by the unit vibration, but also the noise generated by the fluid pulsation in the pipeline system. At this time, the noise value in the ground hall was only 33dB, greatly improving the environment in the hall. The movable cylinder on the vulcanizing press will move upward and downward for the need of loading and unloading the mold. After repeated reciprocating movements, the copper serpentine will suffer from fatigue fracture. Although it can still be used after repair, it will cause time loss if it is stopped for repair. Sandblasting hose company Although it has good soft properties and strong fatigue resistance, it is weak in pressure bearing, temperature resistance, aging resistance and other aspects, and can not continue after several months of use. The good comprehensive performance of sand blasting hose is fully reflected here. In the general industrial field, in addition to pressure and temperature, there are often severe conditions such as fatigue, corrosion, vibration, compression, impact, etc. Under such circumstances, it is most appropriate to use sandblasting hose to compensate for the position movement of the pipeline.
