From the diameter of the size, the largest use of the current pump car is 125 type pump pipe, it can also be high pressure pipe and low pressure pipe, 125 type of low pressure pipe diameter is 133 pipe, and high pressure pipe diameter is 140 pipe.The reason why it is divided into high pressure pipe and low pressure pipe is that with the increase of the length of the boom, the pumping pressure increases, so the pump pipe that can withstand higher pressure is needed.In addition, there are 150 to 125 diameter tube, and 180 to 150 no.2 elbow, and hopper outlet elbow.

From the production process, the pump pipe can be divided into straight seam welding pipe, seamless pump pipe.At present, the pump pipe is generally made of seamless steel tube integral forming technology, and then through a variety of heat treatment.The elbow is connected to the pipe body by welding through a specially processed joint.Then on the two ends of the pump pipe welding flange connection, a pump pipe is basically formed.

From the material, there are ordinary steel, there are wear-resistant materials, such as 45 steel, 45Mn, 55Mn, high chromium alloy and so on, from the service life, of course, wear-resistant material is better, the same thickness, wear-resistant tube longer service life.
