Reference guides on specifying, sizing, and selecting PVC & CPVC duct systems — written by PDI’s engineering team for the engineers, contractors, and facility teams who build with them.
PVC, CPVC, and FRP all replace metal duct in corrosive service, but they are not interchangeable. The gap between them shows up in the field — in service temperature, chemical…

Custom plastic environmental control and containment equipment, fabricated in corrosion-resistant thermoplastics.
Chemical Systems Services, Inc. (CSSI) is a leading custom designer and manufacturer of plastic environmental control and containment equipment, fabricating corrosion-resistant systems from thermoplastics including polypropylene, PVC, CPVC, and PVDF.
An experienced staff of chemical engineers and designers builds systems to each client’s specifications. The range includes PVC and CPVC fittings, blast gates and dampers, scrubbers, fume hoods, tanks and sinks, containment trays, and casework — most fittings stocked for fast delivery, all made in America.
New England’s oldest and largest plastic fabrication house — engineered systems from prototype to full production.
Plastic Design Industries (PDI) uses the unique properties of modern engineering plastics to supply systems and products for industries from biomedical and pharmaceutical to microelectronics and photonics. With automated fabrication equipment and expert computer-aided design, PDI supplies any quantity — from a one-off prototype to a full production run.
PDI takes projects from concept to completion — design, engineering, testing, and validation — spanning cleanroom essentials, fume hoods, wet-process equipment, custom tanks, lab furniture, pure-fluid (PFA) assemblies, casework, and precision welding and machining. ISO 9001 accredited and made in the USA.
