OPW FlexWorks Flexible Piping

Features & Benefits

What Makes This Pipe Different?

Lower installation costs

Increased Pipe Flexibility – the force required to bend the pipe has been reduced to facilitate piping layout. This makes installation quicker and easier, especially in cold weather.
Pipe Weight – has been reduced to facilitate shipping and handling
Pipe Memory – Inherent pipe memory has been reduced significantly to facilitate connection of pipes inside sumps
Redesigned Profile – enhanced leak detection performance
Enhanced Kynar Pipe Liner – fluoropolymer chemical structure makes it dense and permeation resistant
