Note! This chart is intended as a guide for concrete pumping applications and is su
b
ject to the notes,
assumptions, and conditions listed a
b
ove. Any other use of this chart is not recommended.
This chart does not apply to dou

le-wall pipe. Dou
b
le wall pipe can
b
e checked
b
y inspecting the inside of the pipe. If the insert is intact, the pipe is
okay. If the insert is worn through, the pipe must
b
e replaced. Contact your pipe supplier for the pressure capacity of your dou
b
le-wall pipe.
