The Production Stack

Five checkpoints between order and port

Raw material control

Traceable batches of NBR, SBR, HDPE and MDPE — sourced from tier-one Chinese and imported suppliers.

Automated production

CNC extrusion, calendered ply layup, hydrostatic testing and inline wall gauging on every hose and pipe.

Independent QC

Third-party lab certification for tensile, adhesion, aging, ozone and hydrostatic burst per your standard.

Export packaging

Shrink-wrapped, palletised, and container-optimised loading — including 40'HQ and open-top logistics.

Global logistics

FOB Qingdao / Shanghai / Ningbo, with door-to-port arrangement across major shipping lines.

Machinery On Floor

The tools behind every meter

CNC hose calendering lines

Multi-ply calendered rubber layup with tension-controlled ply application, up to DN1200.

Steel-cord spiral machines

High-tensile wire embedded at engineered pitch for suction vacuum + slurry pressure.

HDPE extrusion trains

DN200–DN1600 PE100 pipe extrusion with inline wall gauging and cooling baths.

Rotational float moulding

Rotomoulded HDPE floater shells with foam or air core, in DN200–DN1200 sizes.

Hydrostatic test rigs

Programmable burst and hold-pressure testing to your project spec, batch-logged.

40'HQ container loading bays

Optimised container loading with pre-approved lashing plans and export packaging.

Manufacturing FAQ

How we build, answered

Yes. Hydrostatic, adhesion and burst tests can be scheduled for client or third-party witness (SGS / BV / TÜV). We coordinate the visit and provide safety induction on arrival.

Yes. We can adjust rubber compound formulations for specific slurry conditions — higher abrasion resistance, oil resistance, or temperature tolerance. Minimum order quantity applies.

Every batch is assigned a unique lot number. Raw material certificates, production records and test reports are all linked to that lot number — fully traceable from raw material to delivery.

We stand behind our product. If a defect is confirmed, we arrange a replacement or repair solution immediately — including on-site support if needed. Our goal is to keep your project running.

Yes. We provide customised packaging — steel frames, wooden crates, shrink-wrap, waterproof covering — and loading plans for project cargo, break-bulk, and container shipments.
