Four product lines. One pipeline.
Everything Heartwork ships is built around the same idea — the pipeline is a system, not a shopping list. Pick the family, and we'll spec it to your project.
Sand Suction Rubber Hose
Steel-wire reinforced suction hose — anti-vacuum, anti-kink for pump service.
- ›Model range: SRH-6 to SRH-24
- ›Inner diameter: DN 150 – DN 600 (6" – 24")
- ›Working pressure: 5 – 20 bar (0.5 – 2.0 MPa)
Sand Discharge Rubber Hose
High-pressure discharge hose for slurry, sand and gravel delivery lines.
- ›Model range: DRH-6 to DRH-24
- ›Inner diameter: DN 150 – DN 600 (6" – 24")
- ›Working pressure: 1.0 – 2.5 MPa
Flexible Floating Dredging Hose
Integrated foam floatation — no external floaters required.
- ›Model range: FRH-6 to FRH-24
- ›Inner diameter: DN 150 – DN 600 (6" – 24")
- ›Working pressure: 0.8 – 2.5 MPa
HDPE Dredging Pipe
High-strength HDPE pipe optimized for sediment and slurry conveying.
- ›Nominal diameter: DN 110 – DN 1600
- ›Pressure class: PN 6 · PN 8 · PN 10 · PN 12.5 · PN 16
- ›Wall series: SDR 11 · SDR 17 · SDR 21 · SDR 26
Pipe Floater
MDPE shell, PU foam filled — ideal replacement for traditional steel buoys.
- ›Fits pipe: DN 200 – DN 1200
- ›Shell material: MDPE (medium-density polyethylene)
- ›Core: High-strength polyurethane foam
Not sure which one fits your job?
Match your scenario to a starting recommendation — then let our engineers refine the exact spec.
I need a floating discharge line across open water
PE100 pipe with modular floats gives a repairable, salt-safe train that survives waves.
I'm running abrasive iron/copper tailings
Steel-wire reinforced NBR rubber hose handles high abrasion — customizable wall thickness for extended wear.
Suction line straight off the dredger
Steel-wire / steel-ring reinforced NBR handles vacuum + slurry with the flex you need at the ladder.
Buried inland main for slurry transport
Chemical-resistant, corrosion-free, and butt-fused into leak-proof km-scale runs.
