Qingdao galvanized iron ductThe manufacturer believes that galvanized air ducts are generally divided into three categories according to market materials: galvanized spiral air ducts, stainless steel galvanized spiral air ducts, and composite galvanized spiral air ducts. Among them, the stainless steel air duct is of good quality and strong applicability, but the price is high. The galvanized spiral duct widely used in the market is made of galvanized sheet. Galvanized air duct basically has the characteristics of stainless steel galvanized spiral air duct, but the price is only the 2/3 of stainless steel air duct or even lower. The composite galvanized spiral duct is generally used in the external environment and the requirements for the duct are not high.

Qingdao galvanized iron duct manufacturers believe that the rubber-plastic insulation structure of galvanized air duct is simple and beautiful, and galvanized air duct has been widely used in ventilation and air conditioning projects. Four rubber and plastic pipes are respectively used for rubber and plastic pipes. This process is outdated and backward, with many interface joints, large blanking errors, irregular interfaces, easy cracking, poor appearance quality, large material loss, and high energy consumption.

Qingdao galvanized iron duct manufacturer believes that the thermal insulation construction process of galvanized air duct adopts full plate blanking and single seam bonding, which has the advantages of advanced technology, few interface joints and high blanking accuracy. The single joint is set on the top of the air duct, with firm bonding, good concealment, not easy to crack, and good molding appearance. The insulation board is customized according to the standard section of the French ordinary board duct, which greatly reduces material loss and improves energy efficiency.

　　Qingdao galvanized iron ductThe manufacturer believes that the thickness and specifications of the galvanized air duct can be changed as required. Generally, the two ends of the galvanized spiral duct are always connected with external accessories (such as elbows, reducers, etc.). Usually there are no grooves and sealing rings at both ends. Galvanized air duct has the following advantages:

1. High strength, low resistance, good sealing performance, beautiful appearance, simple installation and long service life.

2. The raw material of galvanized air pipe is galvanized sheet produced by Bensteel.

3. Qingdao galvanized iron duct: smooth inner and outer walls, small air duct resistance, no secondary noise, reduce energy consumption and save operating costs.

4. Galvanized air duct is easy to make, cut, drill, drill and install on site, saving labor and time, and shortening the construction period.

5. There is no need to maintain the galvanized air duct after installation, which reduces the maintenance cost.

　　Qingdao galvanized iron ductThe manufacturer believes that the galvanized air duct is mainly used to connect the air circulation between the two places and play a role in ventilation. Galvanized spiral ducts (made of stainless steel and galvanized white iron sheet) are widely used in the market. The galvanized sheet ventilation pipe of the air conditioner has a normal temperature pipe and a cold and warm pipe, and the temperature change is small and will not cause the pipe to deform. However, the galvanized iron pipe used for smoke exhaust is a high temperature pipe, which will be deformed by ordinary plate flange connection.

The above is about galvanized duct some knowledge, I hope you can seriously learn to understand the relevant knowledge, choose the right products for their own needs.
