Product Description

PTFE Lined Reducing Flanges

Expansion joints in steel mills accommodate movement and absorb vibration in piping systems. In doing so, they protect adjacent piping and equipment from damage.

PTFE Lined Reducing Flanges or Reducing Plates are offered in Wafer style with threaded bolt holes and concentric bores. We manufacture standard reducing flanges which are always in stock with us and can also manufacture special reducing flanges as per customer's requirements.

As a general rule ptfe lined reducing flanges are supplied with a tapered bore, but occasionally due to method of manufacture a parallel bore is supplied. We have a custom-made solution for all transitions between the nominal widths. According to the reduction, lined with PTFE or PFA.

Our PTFE Lined Reducing Flange or Plates can be supplied with virgin unpigmented liners or static dissipating (Anti-static) liners to prevent static build up within piping on site. While a full range of sizes are available, non-standard sizes are our specialty.
