High-Pressure Offshore Rotary Union – Fluid Transfer for Marine Equipment

Description

Introduction of Offshore Fluid Swivels & Rotary Unions

An Offshore Fluid Rotary Union is a critical component designed to transfer fluids such as hydraulic oil, water, steam, or gas between stationary and rotating parts in offshore environments. These rotary unions are engineered to withstand harsh marine conditions, high pressures, and extreme temperatures, making them indispensable in offshore oil rigs, wind turbines, marine vessels, and subsea equipment. Specifically designed for offshore applications, these unions must resist corrosion from saltwater, handle fluctuating pressures, and maintain reliability under continuous operation.

As a leading manufacturer specializing in offshore fluid rotary unions, we provide premium-quality, cost-effective solutions that meet or exceed international standards. Our products offer superior durability, leak-proof performance, and customizable configurations tailored to the demanding requirements of offshore fluid transfer systems. Built with corrosion-resistant materials, high-pressure sealing systems, and rugged bearings, these swivel joints ensure maximum uptime, low maintenance, and long service life—even under continuous exposure to saltwater spray, vibration, and extreme pressure.

Key Features of Offshore Fluid Swivels & Rotary Unions

Saltwater Corrosion Resistance

Constructed from 316L stainless steel, duplex alloys, or titanium to withstand marine corrosion and galvanic attack.

High Pressure and Flow Capability

Handles up to 500 bar (7,250 psi) and supports high flow rates for hydraulic fluids, seawater, or chemical mixtures.

Explosion-Proof & DNV-Compliant

Designed for hazardous environments with optional ATEX/IECEx explosion-proof certification and DNV/ABS marine compliance.

Customizable Sealing Options

Equipped with high-performance seals (FKM, PTFE, carbon-graphite, or mechanical seals) based on fluid type and operating pressure.

Bearings for Offshore Use

Integrated with heavy-duty angular contact bearings or radial roller bearings to ensure stability in rough sea motion.

Applications of Offshore Fluid Swivels & Rotary Unions

Our Offshore Fluid Rotary Unions are trusted in a wide range of demanding marine and offshore applications:

⚓ Offshore Oil Platforms
