Generally, most of the equipment we use is of special structure, so the effect is not so strong. Therefore, we need to pay attention to avoid the oxidation phenomenon of the equipment and adopt corresponding measures to control it. Generally, when this happens, passivation or pickling process is mostly used to avoid oxygenation, so that the anti-corrosion function of C can be advanced. It can be seen that this method is still very important and plays a key role.
In general, we need to choose this process when using hot-dip galvanizing, which also conforms to the aesthetic standards of other developed countries. In this case, we can use the technology to better reflect the 40 year service life of the bridge. As you can see, we still need to understand this technology. In the maintenance of equipment, it is also necessary to consider the content and thickness of multi zinc layer, which is more suitable for the application of Jiangmen bridge.
There are three installation directions of Jiangmen bridge: horizontal device, straight device and air direction. The accessories of the transverse device are all supports; the bridge of the longitudinal device is in the center of the cable to avoid the influence of gravity and scattered; in the air, the use of cross bar, two sling, or sling (hanger) can be used. In general, no matter what kind of device is selected, the support spacing is 1.5m.
In addition, if the cables belong to different systems, isolation can be set on the bridge. If the strong and weak current systems share a bridge, a certain distance should be set according to the rules of the code, or another steel pipe should be set to avoid disturbance.

How to renew the damaged Jiangmen Bridge
Jiangmen bridge plays a very important role in the power industry. The bridge is widely used. The application environment of bridge products in bridges is sometimes bad. The bridge will inevitably be damaged in operation. Usually damaged bridges need to be replaced. Pay attention to safety when replacing bridges. The material of cable bridge is mostly steel. If exposed to various environments for a long time, it will inevitably suffer from corrosion, rust, high temperature burning damage and ext
What are the maintenance steps of Jiangmen bridge and pipeline
With the continuous development of social economy, the use of bridge in Guizhou is also increasingly extensive. As for the bridge, do the usual maintenance and protection work, which can well extend its life. Let's take a look at what protection operations there are. 1. Rust treatment: generally, two layers of chlorosulfonated primer are used for two-part derusting of cable tray. The quality of surface derusting directly affects the life of anti-corrosion engineering. Generally, the field derust
What are the installation requirements for Jiangmen bridge conduit
1. In the engineering design, the bridge should be comprehensively considered according to the economic rationality, technical feasibility, operation safety and other elements, and then the optimal scheme should be confirmed, which also needs to meet the requirements of installation, maintenance and cable placement. 2. When the bridge, trunking and its supports and hangers are used in corrosive environment. Anti corrosion treatment shall be adopted, which shall meet the requirements of engineeri
How to transport Jiangmen bridge and pipeline
Jiangmen bridge is usually customized by the manufacturer. As it is a kind of unconventional product, generally only the manufacturers in the provincial capital will be transported remotely. In the process of transportation, due to the road conditions and the quality problems of the bridge itself, the products will have a certain degree of wear and damage. How to transport the cable bridge? 1. We should ensure the quality of the cable bridge. The quality can ensure the bearing capacity of the br
