Descripción del producto

The concrete pump straight pipe is made of special alloy steel ( *5Mn2). 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. 1. Concrete pump boom pipe or deck pipe Heat treatment process: case hardening by high-frequency induction quenching Wall thickness of the pipe: 4.*0mm, 4.*0mm, 7.*0mm Hardness: HRC**-HRC*2 for inner quenching layer; HRC**-HRC*0 for transition layer; HRC**-HRC*0 for protective layer Service life: ****0 cubic meters
