Guide to the Selection of Corrosion Resisting Non-Metallics Flowserve Corporation has been a producer of non-metallic equipment for the handling of corrosive chemicals for over thirty-five years beginning with the introduction of a cast epoxy formulation, DURCON6. The plastic line has expanded over the years to include PTFE, PFA, and UHMWPE lined equipment, as well as the structural composite materials DURCON 730 and Polycrete. Additionally, many corrosion resistant elastomeric materials, like FKM, CSM, and EPDM, are used in Flowserve's products. The corrosion chart in this bulletin is intended to be a guide for the selection of the proper corrosion resistant, non-metallic material(s) for a given application. The ratings may be used as a guide for material selection but should not be considered a guarantee or blanket recommendation. The ratings are the compilation of extensive laboratory tests, field tests, operating experience, and best judgment. Many factors must be considered when selecting a non-metallic material for a corrosive service. These include: concentration of chemicals present; harmful contaminants; velocity; solids in suspension; type of equipment; continuous or intermittent operation; maximum, minimum, and normal operating temperature; and any other peculiarities characteristic of the solution.
