Key Differences: Molded Full Drain vs. Post-Production Insert

One of the biggest challenges in vertical tank design is maintaining the tank’s integrity while still allowing for the tank to be drained, cleaned, and properly maintained. Some companies create tanks out of one substance and insert a flange, post-production, for drainage. This works fine, to a point, but there are other alternatives, like Poly Processing’s IMFO (Integrally Molded Flanged Outlet).

Evaluating Your Polyethylene Chemical Storage Tank Warranty

Safe and effective chemical storage is expensive, and it might be tempting to purchase a chemical storage system without the added cost of a solid warranty, or with no warranty at all. The problem with that approach is that it might actually cost more in the long term to pay for expensive replacements and repairs.
