High-Pressure Flexible Hose Systems for Offshore & Energy Applications

Nexus Oceanic partnered with Techfluid Yantai Limited, a specialized API-licensed manufacturer of high-performance flexible hose systems engineered for oil & gas, offshore drilling, subsea production, and marine infrastructure.

Techfluid engineers and manufactures steel-cable-reinforced hose assemblies designed to perform reliably under extreme pressure, temperature, and dynamic loading conditions. Featuring integral bonded built-in couplings and true full-bore construction, these systems provide enhanced axial tensile strength, uninterrupted flow characteristics, and improved fatigue resistance — delivering longer service life and greater operational reliability compared to conventional swaged hose assemblies.

API monograms including 7K, 16C, and 17K, alongside international approvals from DNV and ABS, ensure compliance, traceability, and confidence for operators and EPC contractors.

From drilling mud and choke & kill lines to FPSO jumpers and deepwater applications up to 3000m, Techfluid solutions are field-proven across hundreds of offshore projects.

Through Nexus Oceanic, clients receive engineering support, documentation alignment, and lifecycle service coordination — ensuring technically sound, compliant, and commercially optimized delivery.
