Concrete pump inner-hardened pipe

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.

Concrete pump inner-hardened pipe

Wall thickness: 4.0mm, 4.5mm, 5.0mm, 7.5mm etc.
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

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

Because the outer surface behaves like mild steel, the product can be cut and welded with proper procedure in the field, configured into a variety of fittings, and can accept the standard end options of flanges, weld rings and couplings.

Abrasive Applications

One-hundred-twenty-nine-million tons of coal ash—a byproduct of the coal burning process—is produced every year. Most power plants transport the coal ash in liquid form to large surface impoundments or in solid form at landfills near the facility through long lengths of steel piping, which can range in length from several thousand feet to miles.
