In subsea operations, durability is found in the details. While plastic sleeves are common, certain high-stakes environments demand the uncompromising strength of Custom Metal Locking Sleeves. At HYSF SUBSEA, we specialize in precision-machined metal locking nuts available in 316L Stainless Steel and Titanium, providing a level of mechanical protection and thread integrity that standard components simply cannot match.
But what about mobility? For equipment that requires constant movement—such as handheld diver cameras, portable sensors, or ROV manipulators—a standard straight cable is often a liability.
That’s where our Custom Subsea Coiled Cables (Spiral Cables) come in. Engineered with high-elasticity polyurethane (PUR) or specialized marine jackets, our spring cables offer:
- Space Management: They retract instantly, preventing cable entanglement in complex underwater structures.
- Extreme Flexibility: Designed to withstand thousands of extension cycles without losing tension or signal integrity.
- Rugged Interfacing: When paired with our metal locking sleeves, you get a connection that is both mobile and virtually indestructible.
From bespoke thread sizes to specific coil diameters, HYSF delivers the “tough-and-flexible” duo your subsea gear deserves.
Frequently Asked Questions (FAQ)
Q1: Why choose a metal locking sleeve over a standard plastic one?
Answer: Metal sleeves are essential for long-term deployments or high-vibration environments. They resist UV degradation, accidental impacts, and thread stripping. Our custom metal sleeves ensure that your connectors remain securely mated even in the most turbulent underwater conditions.
Q2: Can I customize the length and retraction force of the coiled cables?
Answer: Yes. HYSF provides full customization for coiled cables, including the “relaxed” length, the “extended” length, and the spring tension. We can also integrate various core counts—from power lines to high-speed data pairs—within the same spiral assembly.
Q3: Are these coiled cables rated for deep-sea pressure?
Answer: Absolutely. Our coiled cables are jacketed with pressure-compensated materials like PUR or TPR, designed to maintain their elasticity and insulation properties at depths up to $6000\text{m}$ ($60\text{MPa}$).
Build a more resilient underwater system with HYSF. Whether you need the grip of a metal sleeve or the reach of a coiled cable, we engineer it to last.
