Tri-Mer co-polymer tanks were originally designed for use in hard-coat and hot anodizing operations, where continuous extreme temperatures (32ºF, up to 85ºF and above) are standard.
Tri-Mer co-polymer tanks are fabricated using a proprietary protocol that assures seamless structural integrity and full strength at all bend sites. The Pohang co-polymer tanks were engineered by Tri-Mer to unusually close (±1.5”) tolerances, to fit an existing configuration with strict space limitations. They replace four steel/ rubber brick-lined tanks, which will be demolished as part of the project.
Each Tri-Mer co-polymer tank is manufactured from 1.5” pre-stressed polypropylene sheet, and is 60’ x 6’ x 3’. Tank #1 operates 30% sulfuric acid at 212ºF. Tank #2 is a mixed acid (30% nitric, 15% hydrofluoric) tank operating at 176ºF. The remaining tanks are a uniquely engineered configuration of “two tanks in one” (4 total modules) precisely sloped, with tight center-line requirements. Tank covers, also provided by Tri-Mer, are 1” (European standard gray) polypropylene.
