What is the diameter of a concrete pump line?
The pump pipe diameter how big is said to be the outer diameter of the flange at both ends of the pump pipe, not the diameter of the raw material steel pipe, according to the concrete pump pipe specifications of different models, the diameter of the pump pipe is not the same.

What are the commonly used concrete pump pipe diameters
DN80 mortar pump pipe diameter is 98 mm, DN100 pump pipe diameter has 116 mm and 124 mm two kinds, DN125 pump pipe diameter has 148 mm and 157 mm two kinds, DN150 pump pipe diameter has 175 mm and 184 mm two kinds.

Concrete pump pipe specifications are different, the pump pipe diameter varies greatly, we can determine the pump pipe specification model through the pump pipe diameter. The pump pipe diameter is said to be the outer diameter of the pump pipe flange, not the inner diameter, and the maximum value of the outer diameter is needed in the measurement.
What is the inner diameter of concrete pump pipe
The inner diameter of 80 pump pipe flange is 80 millimeters, the inner diameter of 125 pump pipe flange is 125 millimeters, and the inner diameter of 150 pump pipe flange is 150 millimeters.
