Process Barron fabricates and assembles all non-metallic / fabric expansion joints and frames in-house at our own facilities, for a variety of applications and industries including I.D and F.D fans, ductwork, stacks, baghouses, precipitators and scrubbers. Technical experts are available for field inspection and evaluation services, complete field installation, temporary joint repair and splicing, and turn-key installation. Convenient emergency and standard deliveries are available.
Process Barron stocks fabrics and insulation for manufacturing of a wide variety of fabric expansion joints, with a tolerance range from low temperatures to1800˚F. All fabric materials comply with Fluid Sealing Association (FSA) specifications. Expansion joints made from elastomeric or composite material are available.
Contact Process Barron today to learn more about our fabric expansion joint fabrication capabilities, if you require equipment inspection or emergency field service assistance. Our qualified engineering and service teams are eager to earn your business and help you maintain an efficient operation.
Elastomeric Material Options:
Process Barron’s elastomeric type expansion joints provide high resistance to moisture and chemical corrosion, resistance to vibrations and pulsations, and are ideal for fan discharge and turbine inlet applications.

N250:
Permits continuous use to 250°F. N250 is flame resistant and is compounded to give good resistance to sun, weather and ozone. N250 operates without deterioration in presence of the flue gases, oils, greases, and other petroleum products.
E300E:
Permits continuous use up to 300°F. Chlorobutyl and EPDM have good weatherability characteristics and are excellent against hot air and most flue gases. It cannot be operated in an oil atmosphere without accelerated deterioration.
E400V:
Permits continuous use up to 400°F with short duration excursions to 700°F. Fluoroelastomers are excellent against hot air and have good resistance against oils and minerals acids. They exhibit good weatherabiltiy and have proven successful against chemicals such as SO2 and SO3 found in flue gases.
T1407:
Permits continuous use up to 500°F. F500 is excellent for harsh chemical service in very aggressive wet and dry environment. F500 operates without deterioration in the presence of flue gases, oils, grease, aromatic aliphatic, halogenated hydrocarbons and many acids.
Composite Material Options:
Process Barron’s composite type expansion joints provide the highest resistance to moisture and chemical corrosion, permit continuous use at extreme temperatures, provides resistance to vibrations and pulsations, and are ideal for the most chemically corrosive and extreme temperature applications.

Series C600T, F800, F1000, F1250 are insulated expansion joints for use at continuous temperatures above 400L F. The laminate used for flue gas service is constructed of Teflon impregnated fiberglass fabric which is tightly woven for providing excellent corrosion resistance to SO2, SO3 and NOx, which can attack many other materials.
The soft thermal barrier acts to reduce the temperature that will actually be encountered by the elastomeric cover. The cover will function in a environment well below its normal temperature rating. The elastomeric cover provides a tight seal for both pressure and vacuum, and is capable of resisting the chemicals found in flue gases. Chlorobutyl / EPDM or Fluoroelastomer covers must be used, depending on the specific application. No stitching is used through the construction of the cover other than in the clamped flange area. A variety of acid and resistant stitching materials, such as Teflon impregnated fiberglass, are used to assure high strength and corrosion resistance.
