PVDF Tank Installation Guide

Handling

• Inspect tanks for damage when they arrive, before you accept the delivery. Note any problem on the driver’s bill of lading and the packing list, then call us right away so we can correct it quickly.
• Unload tanks onto smooth surfaces free of rocks and sharp objects. Guard against damage from forklift blades, and use a crane to lift large tanks from the truck.
• Never let the weight of the tank rest on a fitting, and never roll a tank over its fittings.

Installation

• Install the tank on a smooth, firm surface that supports it completely. A reinforced concrete pad is almost always the best base, and a tank stand must also sit on a solid base.
• Secure tanks and stands against movement from wind, seismic activity or motion of the contents. Tie-down systems are available.
• Leave room for maintenance. PVDF expands and contracts with temperature and contents, so plan the space around the tank and the fill level.
• Protect the tank from accidental impact, especially in cold weather, when impact is more likely to cause failure.
• Don’t mount machinery, equipment or heavy loads on the top of the tank or on its fittings.
• If anyone must enter the tank, take precautions against asphyxiation and hazardous vapors.

Fittings & Accessories

• Hand-tighten plastic bulkhead fittings. Over-tightening can cause leaks.
• Fully support all fittings, valves and piping. Fittings should never carry the weight of pipe.
• Use flexible connections or expansion joints so the tank can expand and contract without stressing the fittings.
• Install accessories such as immersion heaters so they never touch the tank wall, and follow the accessory manufacturer’s instructions.

Using Your Tank

• Use the tank only for its intended purpose. PVDF tanks are rated for atmospheric pressure only; never pressurize the tank or pull a vacuum.
• Make sure your chemical is compatible with the tank, fittings, gaskets and accessories. Check PVDF compatibility.
• Don’t store liquids above the service temperature we confirm for your chemical. PVDF handles up to 275°F in some applications.

Before Placing the Tank into Service

Fill the tank with water to test the installation, and confirm the integrity of the tank and every fitting before you put it into use.
