The 80% Fill Rule For Propane Tanks

Nov 29, 2013That means a tank that is 80% full on a mild March day, might register as 85-percent (or higher) at the mid-July cook out. It's the same amount of propane, but it's taking up more space. So the extra space in the tank is a cushion against the pressure that builds up in a tank when it's hot. Get price

Phosphate conversion coating

Process. The application of phosphate coatings makes use of phosphoric acid and takes advantage of the low solubility of phosphates in medium or high pH solutions. Iron, zinc or manganese phosphate salts are dissolved in a solution of phosphoric acid. When steel or iron parts are placed in the phosphoric acid, a classic acid and metal reaction takes place which locally depletes the hydronium Get price
