Deployment Flow
From brief to bubbles on the water
01
Site brief
Share your bathymetry, distance, media, and pumping curve — we handle the sizing.
02
Engineered spec
You get a stamped drawing set: diameter, wall, floater pitch, anchor plan.
03
Factory build
Batched production with hydrostatic, adhesion and buoyancy tests on every unit.
04
Deployment support
Loading plans, on-site fusion support, and spare-parts kits shipped with the line.
Typical lead time from signed PO to shipment: 25 – 45 days.
FAQ
Common questions about deploying with us
Rubber hose DN100–DN1200, HDPE dredge pipe DN200–DN1600, UHMWPE wear pipe DN50–DN800, and matching HDPE pipe floaters for the full range. Non-standard sizes are quoted on request.
Standard rubber hose ships in 25–35 days from PO; HDPE pipe and floaters in 20–30 days. Complex custom builds (jumbo diameter, special compounds) run 45–60 days. Expedited slots are available with prior booking.
Yes. Our engineering desk sizes hose ID, wall thickness, floater buoyancy, anchor spacing and jointing based on your pumping curve and site data. You receive a stamped drawing set with the quote.
Every batch carries mill certificates: hydrostatic test, wall gauging, ply adhesion, and buoyancy check. Third-party inspection (SGS, BV, TÜV) is available on request and can be witnessed at the factory.
Both. Standard DN diameters ship in 40'HQ containers; oversize sections load on open-top or flat-rack. We handle FOB Qingdao / Shanghai / Ningbo and can arrange door-to-port logistics.
For strategic projects we send experienced field engineers to supervise butt-fusion, floater installation, and commissioning. Travel plus per-diem terms are quoted separately.
