Pump pipe generally divided into 125 and 150 and 80 three, and both have high pressure and low pressure. 125 type pump pipe of low pressure model for the outer diameter is Φ 133 pipes, high pressure pipe diameter is Φ 140; 150 type pump pipe of low pressure model for the outer diameter is Φ 159 pipes, high pressure pipe diameter is Φ 168. Pump pipe pipe head tube joint is through special processing, through welding and pipe connection, each pipe connection is through the process of the precision tube card to connect to.
Pump pipe according to the using range and divided into car pump pipe and pump pipe, two car pump pipe including arm tube, hinged elbow, reducer and bend, the cast steel casting and become, straight tube is made of 45 mn2. Owing to it is ordinary 20 # carbon steel by fluid pipe and straight seam pipe, processing and into.
