ABS plastic pipe is a new material with a nominal pressure of 0.6 ~ 1.6Mpa and a linear expansion coefficient of 0.9 mm / (m · ℃). The connection method is flange, bonding, and poor gas permeability resistance. ABS plastic pipe has low flow friction, greatly reducing fluid resistance and pump horsepower, good impact resistance, good mechanical strength and high; impact toughness, only toughness deformation occurs when subjected to a sudden attack.
