Its 3-layer construction comprises 12-strand torque-free uhmwpe braided core, buoyant center core (sg < 1.0) and high-visibility urethane outer coating.

Q: What is the minimum bending radius and operating temperature range for 12-Strand UHMWPE Tow Line?

The minimum bending radius for 12-Strand UHMWPE Tow Line is 8 × OD across its continuous operating temperature range of -40 to +70 °C, ensuring mechanical, hydrostatic and dielectric reliability in subsea and offshore service.

Q: How are the concentric layers of 12-Strand UHMWPE Tow Line arranged from inside to outside?

From inside to outside, the construction sequence is: (01) 12-Strand Torque-Free UHMWPE Braided Core — Twelve high-modulus polyethylene strands (204 t / 407 t MBL); (02) Buoyant Center Core (SG < 1.0) — Floating synthetic core keeping tow & mooring line positively buoyant; (03) High-Visibility Urethane Outer Coating — Abrasion- and UV-resistant yellow polyurethane protective jacket.

Q: What factory test certificates are supplied with 12-Strand UHMWPE Tow Line?

Every production drum of 12-Strand UHMWPE Tow Line undergoes routine conductor resistance/OTDR continuity, high-voltage dielectric and dimensional testing per ISO 10325 12-Strand Torque-Free UHMWPE (Ø 56/80 mm, 204–407 t MBL) Subsea Tow & Mooring Specification, and is delivered with an EN 10204 3.1 factory test certificate.
