The air conditioning in the hall of a giant building is provided by the 6FWB unit fixed in the basement. production Sanding pipe 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. Sanding pipe Price 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.

Henan Sanding pipe Also called pu steel wire pipe, ventilation pipe, dust removal pipe, dust collection pipe, dust conveying pipe, industrial powder dust collection pipe, sweeping car dust collection pipe, drilling machine dust collection pipe, woodworking dust collection pipe, collectively called dust collection pipe. Therefore, industrial food dust transportation and industrial dust transportation are used for dust collection pipe. The production process structure of copper plated steel wire dust collection pipe is to wrap the pipe wall with solid elastic copper plated steel wire spirally, and the pipe wall material is coated with copper plated steel wire with special polyether PUR. PUR material is also called PU material. The thickness of pipe wall can be 0.4mm, 0.6mm, 0.9mm, 1.2mm, 1.5mm, 1.8mm and 2.1mm, depending on the customer's needs. Such as the temperature, wear resistance, flexibility and bending, hydrolysis resistance of the dust collection pipe. It is also necessary to consider whether static electricity is generated in the process of pipe full conveying dust to avoid unnecessary dust explosion and fire. Copper plated steel wire plastic coated dust collection tube is suitable for vacuum suction of powder and particle in industrial and mining, agriculture and water conservancy, civil engineering, food, petroleum, chemical industry, health and other industries, as well as transportation of water, oil, chemical materials, food, etc. Abrasive solids such as dust, powder, fiber, chip and particle, gas and liquid environment, for dedusting and suction plant, Sanding pipe Price Industrial vacuum cleaners, paper and textile fibers, are used as protective tubes. It is widely used in farmland irrigation, industry and mining, oil depot, sand extraction, sand blasting, food, medicine, indoor gas, powder, dust absorption and emission and other fields. This product is a substitute for PVC, rubber and metal pipes.

production Sanding pipe 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. Henan Sanding pipe 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.

Many people don't know much about spiral tube. In fact production Sanding pipe It is very extensive. Spiral air duct is mainly used to connect the two places for ventilation. Spiral air ducts (stainless steel and galvanized iron sheet) are widely used in the market. Spiral air duct market is generally divided into three categories according to material: galvanized spiral air duct, stainless steel spiral air duct and composite spiral air duct. Among them, the stainless steel air duct has good quality and strong applicability, but its price is high. The return air duct of purification system, central air conditioning ventilation duct, industrial air supply and exhaust duct, environmental protection system suction and exhaust duct, mine gas drainage duct, mine coating duct, etc. The spiral duct is first used for ventilation and cooling, which belongs to the category of air duct. It is named according to its purpose, but it can also be used in other places, even for drainage, drainage or as a container, which cannot be called a pipe. Named according to the structure, it should be called spiral grooved thin-walled tube, because it is mainly made of metal, also called spiral grooved metal tube. According to the material name, there may be several names: galvanized (any zinc) (galvanized) (iron), spiral pipe, stainless steel spiral pipe (stainless steel acid resistant steel), aluminum (aluminum) spiral pipe, or in order to distinguish from the existing acid resistant stainless steel pipe, Sanding pipe Price It can be called ultra-thin stainless steel pipe, because it can use 0.3mm or even thinner to roll stainless steel strip.

production Sanding pipe The thickness of the seaming plate shall be within the regular range of products of various specifications. If it is less than the thickness, cracks, wrinkles and other defects are likely to occur during seaming; If it is larger than the large thickness, as the square of the plate thickness is proportional, the bending force will significantly increase, which will cause abnormal damage to the forming roller, overloading of the transmission system, and stuffiness. In dust removal system: galvanized air duct can be used for collection and transportation of dust removal device. In the oil smoke exhaust system: there are a lot of oil smoke in restaurants, restaurants and hotel kitchens, which need to be discharged. The galvanized air duct is suitable, strong, economical and practical. In air conditioning system: galvanized air duct can be pasted with thermal insulation materials inside, and the surface is beautiful. In bulk material transportation: pneumatic transportation system, some finer and looser material particles can be transported by galvanized air ducts, with low cost and good effect. In the ventilation system: supply fresh air and exhaust gas, exhaust harmful gas outdoors, and send outdoor fresh air indoors. The strength of stainless steel plate shall be higher than that of ordinary steel plate. Before seaming with stainless steel plate, forming test shall be carried out first to avoid overloading the equipment and causing excessive wear or mechanical trouble. Due to the poor plasticity of the aluminum plate, it is easy to crack during the forming of the seaming. The forming test should also be carried out before construction. At the same time, because the aluminum plate is lack of elasticity, the aluminum plate air duct cannot be subject to snap seaming. After the zinc coating of galvanized air duct is passivated, dyed or coated with light protection agent, Sanding pipe Price It can obviously improve its protection and decoration. The fireproof function of galvanized air duct is mainly reflected in that it is incombustible, but one thing needs to be noted is that whether its insulation layer is burned depends on the material. We suggest that the galvanized air duct should be made of incombustible insulation materials such as centrifugal glass wool.
