This brochure describes process tank technology using 100% co-polymer and homopolymer polypropylene materials that will not delaminate or embrittle, even with long-term exposure to aggressive chemicals. Tri-Mer tanks also have the distinct structural advantage of double weld strength, inside and out. Tanks up to 100 ft long are custom-built in rectangular, circular, and custom shapes with open tops, cone bottoms, and special access features. Stainless steel tanks are also included.?
