Reducer Submarine Hose

Hongruntong Marine supplies reducer submarine hose (submarine reducer hose). Custom assemblies manufactured & tested to GMPHOM 2009 with full test reports.

As specialized submarine hose manufacturers, Hongruntong Marine designs and produces high-quality reducer submarine hose systems for critical subsea applications. Our submarine reducer hose features precision-engineered tapered connections that ensure seamless pipeline integration while maintaining optimal flow characteristics. These robust submarine hose reducer units are manufactured to meet international standards, providing reliable performance for offshore oil and gas transfer operations where diameter transitions require professional engineering solutions.

Key Features & Benefits

• Precision Reducer Design: Smooth diameter transition reduces turbulence and pressure loss during transfer — improves flow stability and reduces wear.

• High-Strength Reinforcement: Multi-layer textile and/or steel-wire reinforcement delivers excellent burst and working-pressure capacity — increases operational safety.

• Robust Hose Construction: Abrasion- and seawater-resistant inner lining and outer cover extend service life in harsh marine environments.

• Integrated End Reinforcements & Fittings: Reinforced ends and factory-installed flanges/quick couplings ensure secure connections and reduce on-site assembly time.

• Buoyancy & Handling Optimized: Designed for marine handling with buoyant or partially buoyant options to match system requirements — easier deployment and recovery.

• Customizable & Export-Ready: Available in multiple diameters, lengths and reducer ratios, supplied with export documentation and packaging for global delivery.

• Standards Compliance: Manufactured and tested to recognized OCIMF/GMPHOM guidelines (GMPHOM 2009) on request — providing traceable quality and test reports.

Applications

• Subsea pipeline connections

• Offshore platform riser systems

• Single Point Mooring (SPM) installations

• Floating production facilities

• Pipeline repair and maintenance
