“ high quality Cord hose What are the applications in engineering transformation? " In this issue, we will explain this problem for you. Those who have consulted this problem will come to see it: First, we should consider the water supply and drainage of all water related equipment, such as wells, pumps, etc., their location, installation method and temperature, including galvanized air ducts. 2、 It is very important to consider galvanized air duct in advance to avoid temporary replacement of galvanized air duct materials. 3、 After the location of the machine tool is determined, the drainage outlet can be considered to be arranged underground, which is not only convenient but also durable. 4、 After river reconstruction, there should be a suppression test, but now many construction teams do not suppress the test. It is usually said that it is not important, that there is water and pressure in the galvanized air duct, and so on. Try to be present to suppress the test. 5. If the installation is completed, pay attention to the inspection of the workshop, water pump room and FRPP drain. If the drainage system is slow, the installation program should be able to open the installation. Water outlets should be protected, especially during civil engineering construction, Cord hose Price It may cause soil loss and blockage. I believe that you have a better understanding of this information, and we will continue to improve the galvanized air duct to make it more widely used.

Many people don't know much about spiral tube. In fact high quality Cord hose 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, Cord hose Price It can be called ultra-thin stainless steel pipe, because it can use 0.3mm or even thinner to roll stainless steel strip.

Daqing Cord hose The quality is closely related to the material selection and the manufacturing process. 1. The galvanized air ducts of different specifications are made of plates of different thicknesses according to the specification requirements. On the basis of being familiar with the size and layout of the air duct in the drawing, skilled technicians will set out and cut the material to ensure that the air duct production and installation meet the relevant standards. 2. The galvanized sheet air duct flange will be made uniformly according to the series of specifications specified in the drawing. In addition, the bolt holes of the flange will be punched at a fixed distance with a punch and a mold. The forming welding of the flange will also be positioned with a special mold to ensure that the air duct flange of the same specification has interchangeability. Compared with the traditional galvanized iron pipe made by hand, the round galvanized air pipe made by mechanism has the following advantages: (1) The round galvanized air pipe has good sealing performance. (2) Both strength and rigidity are good. (3) The ventilation resistance is small, the ventilation noise is small, and the round pipe is better than the square pipe. (4) The galvanized air duct is easy to install and has few connection points. (5) Circular high quality Cord hose High grade, beautiful appearance. Galvanized spiral duct is very suitable. Generally, galvanized air ducts are used, while stainless steel pipes are very suitable for galvanized spiral air ducts in corrosive and particularly humid places. Generally, galvanized air ducts are used, while stainless steel pipes are used in corrosive and particularly humid places.

high quality Cord hose 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, Cord hose 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.
