Pump pipes are generally divided into 125 and 150 types, and these two types have their own high and low pressures. The low pressure type of 125 pump pipe is 133 pipeline with outer diameter, the high pressure type is 140 pipeline with outer diameter, the low pressure type of 150 pump pipe is 159 pipeline with outer diameter, and the high pressure type is 168 pipeline with outer diameter. The pipe head of pump pipe is a specially processed pipe joint, which is connected with the pipe body by welding. The connection of each pipe is connected by a pipe clamp manufactured by the investment casting process. Pump pipe can be divided into towing pump pipe and ground pump pipe according to the scope of application.
