File Name – Date - Owner of File Welcome! TANK BLANKETING Its Theory and Purpose, The Process and Its Setup

File Name – Date - Owner of File What is Tank Blanketing? Very simply, it is the process of maintaining a slightly positive pressure in a closed storage tank, vessel or container with an inert gas during pump-off or thermal contraction events.

File Name – Date - Owner of File What is Vapor Recovery? Very Simply, it is the process of maintaining the upper operating pressure in the tank vapor space during filling or thermal expansion events.

File Name – Date - Owner of File Why Use Tank Blanketing?  Prevents Air, Moisture or other Contaminants From Entering the Vessel  Protect Against Product Spoilage or Deterioration  Protect Against Vapor Space Ignition  Protect Against Tank Corrosion

File Name – Date - Owner of File Benefits of Tank Blanketing/Vapor Recovery  Longer Storage Life  Higher Quality Products  Less Oxidation  Eliminates Flammable Vapor Space  Less Tank Corrosion  Reduced Emissions  Enhances Safety

File Name – Date - Owner of File PPS Seat & Pallet Outshines Stainless Steel When Subjected to Chemically Hostile Environments Material selection for the operational components of the valve is crucial for the valve’s performance and reliability. Many applications subject the valve to stored or processed vapors which can be chemically hostile, corrosive and sticky, as well as to harsh environmental conditions such as extreme cold and heat. These conditions are the prime causes of deterioration, pitting, sticking and freezing which cause valve leakage and possible valve failure. When used for valve seat ring and trim, PPS material provides greater resistance to these destructive factors when compared with conventional metal materials, such as, aluminum, ductile iron, carbon steel and stainless steel. Seat Pallet PPS is superior to Stainless Steel and equivalent to Hastalloy in corrosive and chemically hostile applications, thus insuring seal longevity.
