Color: according to customers' requirement
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

4.Hardness:
-
HRC58-HRC62 for inner quenching layer;
-
HRC35-HRC40 for transition layer;
-
HRC25-HRC30 for protective layer
