1.concrete pump pipe is made of special quality steel which is quenched and carried 

out carburizing chemicaltreatment on the inner wall.

2.The hardness of the flanged bushings can reach 58-60 degrees and the serving life of

pipe line can increase 3  - 5 times, which enables users to save time and cost, enhancing the production efficiency.

   The three generations of Concrete Pump Delivery pipe
  ST52 Steel Pipe 

St52 steel pipes are made from ST52 ,and the lowest Capacity 

of ST52 steel pipe is 8000cubic metres.

And we could add the  Wear-resistant electrode in the 

ST52 steel pipe to expande the working life


45Mn2 Steel Pipe

 and 55Mn steel pipe


Hardening inside is the reason why this generation

 steel pipe's working life can be 20000 cubic metres.


Twin wall Wear-resisting concrete 

pump pipe.


This generation pipes have two layer. Material of the inner wall is wear-resisting material and the material of outer is ST52.

Capacity of the third generation is 40000Cubic meters
