Holz PTFE Molded Expansion Joints are spool-type flexible couplings designed to compensate for movement and abate noise in severe corrosive environments such as chemical processing, petrochemical, power generation, pulp and paper manufacturing, water and wastewater applications. Highly engineered and designed and built for use in the most extreme applications, Holz PTFE Molded expansion Joints can be used where metallic joints/lap joints, or PTFE and FEP-lined may have been previously specified or used.

All Holz PTFE expansion joints are delivered complete with ductile iron flanges and control units ready for immediate installation in the field. Flanges in other alloys are available by special order. Call for availability of other materials. Flanges are protected to resist atmosphere corrosion and are tapped to the ANSI standard drilling of 150 Ibs.

Control units are assembled with flanges to prevent joints from excessive axial elongation. Holz sets the tie rods at the factory at the maximum face-to-face working limits, with lock nuts protecting against overextension.
Holz PTFE Molded Expansion Joints are available in 2,3, 4 or 5 convolutions in a wide variety of dimensions and operating temperatures.
