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.
 
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.
 
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.
 
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 airtightness is very good.
 
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.
 
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.
 
7 Oil Gauge
The oil gauge is designed and manufactured according to the measuring of the tank. The nether of the oil gauge should immerse into the liquid more than 100mm depth. The upper is the flexible rubber sealing.
 
8 Anti-rotation Device
The anti-rotation device could control the waggle or swing of the the internal floating roof upon the liquid in case the internal floating roof has big rotation and center position shift.
 
9 Anti-static Device
The anti-static device is to output the static from the internal floating roof to the earth to prevent the fire accident due to the static on the internal floating roof which is caused by the loading or unloading of the liquid in the tank.The ground resistance is less than 10Ω.

Swivel joints are precision components for the connection between stationary pipes (or hoses) and rotating parts of machines. The function is the transport or gaseous, liquid or semi-solid substances from and to machines. 

There are three kinds of loading arms: Marine loading arm, truck loading arm, rail car loading arm. A loading arm permits the transfer of liquid or liquefied gas from one tank to another through an articulated pipe system considering or rigid piping and swivel joints to obtain flexibility. Transfer to or from a truck transported tank ot rail transported tank requires a top loading arm or a bottom loading arm.
A Marine loading arm, also known as a mechanical loading arm, loading arm, or MLA is a mechanical arm considering of articulated steel pipes that connect a tankship such as an oil tanker or chemical tanker to a cargo terminal.
