PVDF Short Radius 90° Bend
A PVDF Short Radius 90° Bend is a pipe fitting that changes the flow direction of a pipeline by 90° degrees while having a short centerline radius. The centerline radius (R) is approximately equal to the pipe diameter (1D). That produces a sharper turn than a long-radius bend, which is suitable for installations with limited space. Its short-radius design is ideal for applications where space is limited and sharp directional changes are required, making it highly suitable for chemical processing, oil & gas treatment plants, semiconductor manufacturing, and other corrosive industrial environments.
The PVDF Short Radius 90° Bend is a high-performance pipe fitting designed to change the flow direction of PVDF piping systems at a right angle within a compact space. Manufactured from Polyvinylidene Fluoride (PVDF), this bend offers excellent mechanical strength and outstanding chemical resistance.
