Pump Pipe

Pump Pipe

Pump pipe is a very important accessory for pump truck. And itsapplication increases efficiency of the construction by nearly a hundredfold. Traditionally, concretewas transported to destination by human or crane in the form of barrel. Specialmaterial, quenching treatment of inner wall and chemical treatment ofcarburization are used to enable hardness of the flange bush reach 60 degrees.In addition, hardness and wear resistance are also increased to ensure 3-5years’ service life of this product. As a result,time and cost can be saved and trouble of regular changing is also eliminatedto improve efficiency.

In order toresolve connecting problem of flange, we improve our technology. Specifically, 3m tube is used and heat treatment is performedafter flange is connected and welded. After overall quenching, it has betterquality and partial annealing or weak socket is avoided. For tube head, it isprocessed specially and it is connected through welding. For connection of eachtube, it is realized through pipe straps processed by fine casting. For raw material of pump pipe, customization is available.Inner tube has excellent abrasion property and high strength. For outer tube,it has good toughness.      

Thereare some attentions and cautions for pump pipe. Tube at the bottom cornerwithstands a lot of pressure when pumping concrete vertically upward, so it isprone to break. As a result, this position should be firm. So repeated firmingshould be avoided and concrete pad can be casted atthis position to facilitate cleaning of tube.
