AmeriChem manufactures polypropylene tanks using Wegener Automated Bending and Butt-welding equipment. Using this type of equipment, we are able to eliminate the hand-welded corners found in conventionally constructed tanks. Since this is one of the areas most likely to leak, AmeriChem's construction techniques eliminate this as a potential problem.

Additionally, AmeriChem constructs the bottom of the tank considerably different than most manufacturers.  The bottom is sized slightly larger than the external dimensions of the sidewalls. The bottom is not placed inside the tank, but rather welded to the bottom of the tank sidewalls. The exterior is jet-welded with approximately 1/4" thick molten polypropylene.  This style of construction makes it virtually impossible for leaks to occur along the bottom of the tank.

Advantages of using Wegener automated bending and butt-welding equipment are:

1. No Air Gaps
2. Solid Walls
3. Perfect Corners Every Time
4. Structurally Superior
5. Never Leaks
6. Long Operating Life

Disadvantages of using hand-welded tanks are:

1. Air Gap At Corners
2. Non-uniform Welds
3. Non-uniform Corners
4. Structurally Weak
5. May Leak
6. Production Shut-down For Tank Replacements
