Covering and sealing treatment of sewage tanks can effectively prevent waste odorous gas from polluting the environment. Many companies now adopt the capping method. This method not only protects the surrounding environment, but also prevents the waste gas in the sewage tank from contacting air. Due to different industrial production, the exhaust gas composition produced is different, and the material and installation requirements are also different. The following is an introduction to the differences in sewage tank capping and sealing projects in different fields:
1. Different requirements for materials
The anti-hanging membrane sealing of the sewage tank depends on the gas composition of the sewage tank. In principle, the more complex the waste gas composition of the sewage tank, the stronger the corrosiveness, and the higher the quality requirements of the membrane material.
2. Different installation methods
Generally speaking, the connection method between steel structures is mainly welding, but in some on-site environments, open flames are not allowed, such as in the petrochemical industry, the installation method of the anti-hanging membrane must be changed, and welding shall be changed to bolted connection.
3. The difficulty of construction is different
The higher the concentration of exhaust gas, the greater the difficulty of sealing and the longer the required construction period.
The above is the difference between the sewage tank capping projects in different fields. If you have any questions about the sewage tank capping project, Shanghai Zhanji Membrane Structure Company welcomes your consultation 400-607-8793
