Marine Breakaway Couplings (MBCs)

Hongruntong Marine (marine breakaway coupling manufacturer) supplies petal valve marine breakaway couplings, marine breakaway coupling (single/multiple) with competitive price for offshore, oil tanker & marine fuel transfer.

Hongruntong Marine provides high-performance Breakaway Couplings designed for offshore oil transfer systems, manufactured in full accordance with OCIMF 2009 standards. These couplings serve as critical safety devices in floating hose assemblies or SPM/STS operations, ensuring immediate shutoff and separation during over-tension or emergency disconnection scenarios. As a professional marine breakaway coupling manufacturer, Hongruntong focuses on developing high-safety fluid transfer solutions for marine scenarios, covering standard marine breakaway coupling (single-unit), marine breakaway couplings (multi-unit systems), and specialized petal valve marine breakaway coupling (for high-pressure fuel/oil transfer).

We offer two main types to suit different operational preferences:

• Petal Type: Features a petal-shaped valve system that provides efficient sealing with minimal pressure drop, ideal for high-flow operations.

• Flip Flap Type: Employs a flap valve design for quick response and compact structure, suitable for space-restricted offshore systems.

Technical Parameters

Why Choose Hongruntong?

• Production Scale: 5,000+ square meter factory with 3 production lines (single-unit, multi-unit, petal valve); monthly output of 200+ sets (meets bulk order needs).
• R&D Capability: 10+ engineers with 8+ years of marine coupling experience – can customize petal valve marine breakaway coupling for non-standard pressure/flow requirements (e.g., 10.0 MPa high-pressure models).
• Quality Control: 100% product testing (pressure test, disconnection cycle test, corrosion test) – each marine breakaway coupling comes with a test report and certification (ABS/DNV/CCS).

Scenario-Specific Safety & Durability

• Seawater Corrosion Resistance: All products use duplex stainless steel or 316L – 5000-hour salt spray testing shows no rust or coating peeling (service life up to 10–15 years in marine environments).

• Emergency Reliability: Breakaway mechanism triggers within 1 second (avoids hose pulling damage); self-sealing valves close within 0.3 seconds (minimizes fluid leakage).

• Easy Maintenance: Modular design allows replacing only damaged parts (e.g., sealing rings, breakaway joints) – no need to replace the entire coupling, reducing maintenance cost by 40%.

Quality Assurance Process

1. Raw Material Inspection: Duplex stainless steel 2205/2507 is tested for chemical composition (Cr≥22%, Ni≥5%) and mechanical properties (tensile strength ≥620 MPa); sealing materials (PTFE) are checked for high-temperature resistance.

2. Component Manufacturing: Valve cores (especially petal valves) are precision-machined (tolerance ±0.05mm); breakaway joints are forged (no internal cracks) and heat-treated.

3. Assembly & Testing:

   • Pressure Test: Each coupling is pressurized to 1.5× rated pressure for 24 hours (no deformation or leakage).

   • Disconnection Test: 1,000+ breakaway cycles (simulates ship drift) – mechanism works normally, no wear.

   • Corrosion Test: Salt spray testing (5000 hours) for marine compatibility – no rust or sealing failure.

4. Certification & Delivery: Products pass ABS/DNV/CCS certification; packed in seawater-resistant wooden cases (prevents damage during ocean shipping); accompanied by installation manuals and test reports.

FAQ

Q1: What is a marine breakaway coupling?
A: A marine breakaway coupling is a safety device installed in fuel or cargo transfer lines on vessels and terminals. It automatically disconnects in case of emergency or excessive load, preventing spills, equipment damage, or environmental hazards.

Q2: What types of breakaway couplings are available?
A: Hongruntong offers petal & flip-flap valve breakaway couplings, as well as standard and custom designs, suitable for different flow rates, hose sizes, and marine applications.

Q3: What materials are used in marine breakaway couplings?
A: Couplings are made from high-grade stainless steel, or other corrosion-resistant alloys to withstand harsh marine environments and long-term operation.

Q4: How do I choose the right marine breakaway coupling for my vessel?
A: Selection depends on hose diameter, operating pressure, flow rate, and emergency load requirements. Hongruntong provides engineering support to specify the correct model for your application.

Q5: Are Hongruntong marine breakaway couplings certified?
A: Yes. Our couplings comply with international marine safety standards and classification requirements, ensuring reliable and safe operation during fuel or cargo transfer.

Q6: Can you provide pricing and bulk order options?
A: Yes. Hongruntong offers competitive marine breakaway coupling prices and can supply bulk orders worldwide. Contact our sales team for a tailored quotation and shipping details.
