Installation corrosion protection

Because the gas supply has seasonal and temporal changes, and the gas source cannot rapidly change the gas production in a short time, a gas holder must be installed to balance the load of the transmission and distribution system and adjust the imbalance between gas production and gas consumption. How to install the spiral guide rail type gas holder gas holder is generally a balance adjustment facility for storing gas. The structure of the diagram of the installation process of the gas holder is generally composed of a fixed water tank and a tower section and bell cover that can be used for spiral lifting. 10000m ³ The main structure of how to install the spiral guide rail type gas holder is composed of steel water tank, tower body, top frame, top plate, inclined ladder, counterweight, handrail, etc. Its main features are: large cabinet volume, complex components, high weld density, large welding deformation, strict requirements for sealing performance and lifting flexibility between water tank, tower section and bell cover, and great difficulty in manufacturing and installation. The main components of the gas holder installation shall be prefabricated on site and installed after being pre-assembled into large pieces or large pieces with moulds.
