Double-Layer Delivery Pipe Specifications

Twin-wall construction combines an outer load-bearing pipe (Q345 or ST52) with an inner wear-resistant sleeve (CR28 / CR23 / CR15 / NM600) inserted into the pipe head. This configuration resists the impact and high-intensity wear of fresh concrete far better than single-layer pipe, multiplying service life by 3 to 5 times in high-output truck-mounted pumps.
| Outer Diameter | Outer Material | Outer Wall Thickness | Inner Material | Inner Wall Thickness | Working Pressure | Wear Grade |
|---|---|---|---|---|---|---|
| DN125 / 5 inch | Q345 | 3.0 mm | CR28 | 5.0 mm + 4 mm sleeve | 130 bar | 13 |
| DN125 / 5 inch | Q345 | 2.8 mm | NM600 | 4.2 mm | 130 bar | 6 |
| DN125 / 5 inch | Q345 | 2.0 to 3.0 mm | NM600 (boom) | 3.5 to 3.0 mm | 85 bar | 6 |
| DN125 to 100 (reducer) | ST52 | 4.0 mm | CR23 | 8.0 mm | 30 bar | 10 |
| DN150 to 125 (reducer) | ST52 | 4.0 mm | CR28 | 8.0 mm | 130 bar | 13 |
| DN150 to 125 (reducer) | ST52 | 4.0 mm | CR15 | 8.0 mm | 130 bar | 6 |
| DN125 to 100 (reducer) | ST52 | 4.0 mm | CR28 + CR15 | 8 mm + 3 mm | 130 bar | 8 |

Double-Layer Elbow & Cast-Steel Elbow Family

Elbows take the highest wear in any concrete-pump delivery system because the concrete stream changes direction against the inner wall. Choose the right wear grade to match your daily output and aggregate hardness.
| Series | Angles | Inner Layer | Outer Layer | Wear Grade | Recommended For |
|---|---|---|---|---|---|
| CR28 elbow (MTWCR28E) | 10 / 20 / 30 / 45 / 90 deg. | CR28 | ST52 | 13 | High-output truck-mounted pumps, high-abrasion aggregates |
| CR23 elbow (MTWCR23E) | 10 / 20 / 30 / 45 / 90 deg. | CR23 | ST52 | 6 | Heavy-duty twin-wall reducers, mixed aggregate |
| CR18 elbow (MTWCR18E) | 10 / 20 / 30 / 45 / 90 deg. | CR18 | ST52 | 3 | Standard twin-wall elbows, general construction |
| CR15 elbow (MTWCR15E) | 10 / 20 / 30 / 45 / 90 deg. | CR15 | Q235 | 3 | Cost-efficient replacement, light to medium wear |
| Cast-steel elbow (NM13) | 15 to 90 deg. | NM13 cast steel | — | — | PM / ZOOMLION / SANY / XCMG / LOXA direct fit, no adapter |

Material & Heat-Treatment Technology

The wear grade of a concrete-pump delivery pipe is decided by three variables: inner-layer material chemistry, inner-layer wall thickness, and the heat-treatment process applied to the inner sleeve. We control all three to match the wear grade your application requires.
| Inner-Layer Material | Hardness Range | Wear Grade | Recommended Use |
|---|---|---|---|
| CR28 | ≥ 60 HRC | 13 | Pumping platform of high-output truck-mounted pumps, most demanding wear point |
| CR23 | 58 to 62 HRC | 10 | Twin-wall reducers, heavy-duty bends |
| CR18 | 56 to 60 HRC | 6 | Standard double-layer elbows |
| CR15 | 56 to 60 HRC | 6 | Small-bore twin-wall pipe, cost-efficient replacement |
| NM600 | High-chromium wear steel | 6 | Platform and boom pipe with high-abrasion aggregate, long boom |
| 55MN (heat-treated) | HRC 62 to 65 | 3 | Single-layer pipe, trailer-pump boom, mid-range wear |
| ST52 (carburized) | 2 mm @ HRC 60 to 62 | 3 | Outer layer, carburized reducer |
| 37MN5 | 9 mm single-layer | 3 | Reducer pipe, standard trailer-pump flange |
