The cover is a vital process vessel element subjected to the same working conditions as the vessel or tank it seals - conditions such as high corrosion, elevated temperatures, vacuum, high pressure, PH changes etc.

There are very few construction materials in the chemical industry that can withstand these working conditions while still properly sealing the vessel. Among them one can find Rubber lined, Exotic alloys and glass lined.

Fluoropolymers lined covers are not commonly used in the industry due to two main reasons:

 

• Vacuum can swell the lining.

• Thermal expansion that can lead to changes in the geometrical form of the lining.

Engiplas introduces a unique solution for the above; If properly bonded to steel, fluoropolymers keep their excellent characteristics at any given temperature and pressure while keeping their initial form.
