A PVDF Butt-Weld Reducing Coupling is a high-performance fitting designed to connect two pipes of different diameters in corrosive and high-purity piping systems. Manufactured from Polyvinylidene Fluoride (PVDF), it ensures a seamless, reliable transition where chemical resistance and flow integrity are critical.
Key Advantages
Leak-Free & Strong: Butt-welding creates a permanent, homogeneous joint as robust as the pipe itself.
Superior Chemical Resistance: Ideal for handling aggressive acids, solvents, and halogens.
Smooth Flow Transition: The concentric design minimizes turbulence and prevents particle accumulation.
High Purity: Perfect for applications where contamination must be avoided, such as in pharmaceutical or semiconductor processes.
Common Applications
Chemical processing lines
Ultra-pure water (UPW) distribution
Semiconductor chemical distribution systems (CDS)
Pharmaceutical and biotech process piping
Quick Installation Overview
The coupling is installed using a thermal welding process (with a PVDF Iweld or hot air welder):
Clean and prepare the pipe ends.
Heat the pipe ends and coupling sockets simultaneously.
Quickly join the components and hold in alignment.
Allow the joint to cool completely for a permanent, monolithic bond.
Choose PVDF reducing couplings for a reliable, corrosion-resistant solution for changing pipe diameters.
