1. INTRODUCTION FOR INTERNAL FLOATING ROOF COMPONENTS
1.1 Pontoons
The pontoon use seamless aluminum pipe which is extrusion molding to make sure its tightness. The design buoyancy is twice over the total weight of the internal floating roof.
1.2 combined skeleton
The skeleton is made of kinds of aluminum profile. The margin plate designed to immerse into the liquid more than 100mm depth.
1.3 Vents
When the press of the oil gas below the internal floating roof comes to 0.01Kgf/cm2, the vents could open automatically to drain the air and oil gas out. When the internal floating roof descend to the lowest position, the vents also could open automatically.
1.4 Manhole
The manhole is designed to open freely to make sure of the installation and the man could go through conveniently. The round of the manhole is sealed with suitable sealing. The nether frame of the manhole should immerse into the liquid more than 100mm depth. The air tightness is very good.
1.5 Support Leg
The support leg is installed under the internal floating roof to make installation and maintaining convenient. The leg is made of seamless aluminum pipe which is placed equality under the internal floating roof. Their load capacity is more than the critical pressure of the internal floating roof and its height could be adjusted freely according to the structure of the tank bottom.
1.6 Sealing
Using which kind of sealing is according to the liquid handled in the tank or the different welding line of the tank wall. Tongue shape and balloon shape sealing are the main style of sealing tape.
