Chemical Infrastructure for High-Purity Magnetics Manufacturing
DVS 2205-style extrusion-wound HDPE and polypropylene tanks are engineered for southeastern magnetics facilities. They support aggressive commissioning schedules, nickel sulfamate plating chemistry, rare-earth slurry mixing, and wetlands-adjacent SPCC requirements.
Purity-Critical Materials
Natural polypropylene for nickel sulfamate and high-purity plating baths — zero pigments, zero fibers, no leachables.
Tank-As-Structure Engineering
Direct 1-ton mixer load support with welded baffles and variable wall profiles — no external steel gantries above your chemistry.
German Design, U.S. Delivery
DVS 2205 extrusion-wound cylinders built for creep control, thermal cycling, and 20+ year service in rare-earth processing lines.

Frequently Asked Questions
What material is used for nickel sulfamate plating tanks?
Natural polypropylene with zero pigments and zero fibers is specified for nickel sulfamate and other high-purity plating baths, eliminating leachables that would contaminate the plating chemistry.
Can these tanks support a mixer without external steel supports?
Yes. Tank-as-structure engineering with welded baffles and variable wall profiles provides direct support for up to a 1-ton mixer load, eliminating the need for external steel gantries.
What design standard do Houston PolyTank expansion tanks follow?
DVS 2205, a German thermoplastic vessel design standard, engineered for creep control and thermal cycling with a 20+ year service life in rare-earth processing lines.
What is the typical lead time for a custom expansion tank?
4–6 weeks for U.S. manufacturing, which supports aggressive commissioning schedules for magnetics and plating facility buildouts.
