What Is The Difference Between Schedule 40 and Class …

The Difference Between Schedule 40 and Class 200 PVC Growing up, I knew there was a difference at the local home improvement store between schedule 40 PVC and schedule 80 PVC when I held the pipe in my hands. Other than one being heavier and gray, I

The Benefits of CPVC Fire-Sprinkler Systems - BUILDINGS

Pipe size and fluid velocity influence friction loss. CPVC pipe has a C-factor of 150; steel pipe''s C-factor is 120 when it''s new, and decreases as it ages, due to scale build-up. A higher C-factor value results from the pipe being smoother and providing better friction

FAQ C Factor - Performance Pipe

The C factor for HDPE butted fused pipe was found experimentally to be about 155. A conservative design value is 150. DI manufacturers publish an initial value of 140 for cement lined DI pipe. Many engineers assume that this value will be reduced over the life of a

What''s the Difference Between PVC and CPVC Pipe

Always check the manufacturer printing on the pipe to be sure.Because of the differences in chemical makeup, sometimes PVC or CPVC also require different primers and solvents for connecting pipe and fitting joints.The creation of a strong joint depends on the
