After completion of the deck assembly and welding, central ring was assembled on a temporary column and by means of temporary support around the internal circumference of the shell, ring girder and all of rafters and gusset plates were erected and welded. Afterwards, roof plate’s installation commenced according to sketch plate erection and then roof plates welded to each other. At the next step, hanger clips on the rafter, girder and stiffener of deck, were installed and finally suspended deck hanger was erected (see fig.1-4). Also six nozzles were cut and then welded on roof plates on proper position Necessary accessories for air rising In order to perform air rising correct

The Innovative Method of Oil Tank Roof Air Raising

In the world of oil storage, efficiency and safety are paramount. Oil tanks are an essential part of the energy industry, providing storage for vast quantities of valuable resources. Over time, innovations have emerged to improve the maintenance and reliability of these tanks. One such innovation is the technique of oil tank roof air raising, a method that has revolutionized the industry. *Understanding Oil Tank Roof Air Raising* The process of oil tank roof air raising involves precisely controlling the air pressure within the tank to lift its roof. This method is especially beneficial for large, floating-roof storage tanks commonly used in the oil and gas industry. Here's how it works: 1. **Roof Design:** Floating-roof tanks are designed with an internal roof that "floats" on the surface of the stored liquid. This design minimizes the vapor space above the liquid, reducing the risk of flammable vapors. 2. **Safety and Maintenance:** Periodically, these tanks need mainte
