Rubber STS Hose High Pressure Anti Corrosion Flexible Long Service Life
Description
The Rubber STS Hose is designed for ship-to-shore liquid transfer operations where safety and reliability are critical. Built to handle petroleum, crude oil, and refined chemical products, these hoses provide superior elasticity and shock absorption compared to rigid transfer pipelines. Their robust rubber compound ensures durability under harsh marine conditions such as UV exposure, salt spray, and abrasive deck handling.
Case Study: Oil Terminal, Singapore
An oil export terminal faced frequent downtime due to pipeline maintenance and leakage issues with old composite hoses. By switching to Rubber STS Hoses, the terminal reduced hose failures by 70%, saving an estimated USD 250,000 annually in maintenance and downtime. The hoses’ superior flexibility also shortened vessel loading times by 12%, directly increasing terminal throughput.

Features
High Elasticity Structure
Rubber provides superior flexibility, absorbing shock loads caused by vessel motion. Unlike rigid pipes, it prevents sudden stress concentrations, extending hose service life.
Example: During heavy swells, the hose bends smoothly without kinking, ensuring continuous liquid transfer.
Multi Layer Reinforcement
Designed with textile and steel wire reinforcement layers, the hose can handle SWL up to 21 bar working pressure. This prevents bulging and rupture under high flow rates.
Compared to standard hoses, reinforced rubber maintains its shape under surge pressure, reducing burst risks.
Anti Corrosion Rubber Compound
The inner lining is resistant to oil, chemical solvents, and seawater ingress. This ensures minimal degradation even in aggressive cargo transfers.
Value: Reduces replacement cycles, cutting lifetime cost of ownership by 40% compared to conventional hoses.
Enhanced Safety Coatings
External layers are treated with UV stabilizers and anti-abrasion coatings, making them ideal for long-term outdoor storage.
Advantage: Maintains integrity even after prolonged sunlight exposure, unlike cheaper uncoated hoses.
Applications
Oil and Gas Terminals
Operation: Connects ship manifold to shore pipeline for crude or refined petroleum. Requires grounding cables to prevent static buildup.
Safety Note: Regular inspection for wear at coupling points is critical.
Chemical Tankers
Resistant to a wide range of liquid chemicals. Operators must verify chemical compatibility with inner lining before transfer.
Floating Storage Units (FSU)
Flexible enough to withstand tidal changes. The hose allows for dynamic positioning of vessels without interruption.
Emergency Bunkering
Portable and quick to deploy during offshore refueling. The lightweight rubber body reduces crew handling fatigue.

FAQ
1. Q: What is the maximum working pressure of your Rubber STS Hose?
A: Standard models operate up to 21 bar. Higher ratings are available upon request with reinforced layers.
2. Q: How should the hose be stored when not in use?
A: Store in a shaded, dry place, coiled loosely without sharp bends. Avoid contact with petroleum residues to extend service life.
3. Q: Can it be used in sub-zero temperatures?
A: Yes, with low-temperature rubber compounds the hose remains flexible down to -30°C. Standard versions are rated from -20°C to +80°C.
4. Q: What maintenance is required?
A: Inspect couplings, outer cover abrasion, and inner lining wear quarterly. Replace if cracks, bulges, or reduced flow are detected.
