The Concrete Pump Pipe is made of special quality steel which is quenched and carried out carburizing chemical treatment on the inner wall. The hardness of the flanged bushings can reach 58-60 degrees and the serving life of pipeline can increase 3-5 times,which enables users to save time and cost, enhancing the production efficiency.

1.The concrete pump straight pipe is made of special alloy steel ( 45Mn2). The inner pipe wall is case hardened by CNC high-frequency induction hardening machine. The inner pipe wall becomes a wearable layer with high hardness. The service life of the inner-hardened concrete pump boom pipe is as 3 to 5 times as normal concrete pump pipe. 
2.Heat treatment process: Case hardening by high-frequency induction quenching 
3.Wall thickness of the pipe: 4.00mm, 4.50mm, 7.50mm

4.Hardness:

HRC58-HRC62 for inner quenching layer;

HRC35-HRC40 for transition layer;

HRC25-HRC30 for protective layer
