Marine-Grade Rotary Union for Ship Piping Systems – Corrosion Resistant

Description

Product Overview: Ship Pipeline Rotary Union

The Ship Pipeline Rotary Union is a high-performance mechanical device engineered to transfer various fluids—such as water, oil, steam, hydraulic fluids, and air—between stationary pipelines and rotating or moving parts on ships and marine vessels. Designed for reliability in harsh maritime environments, this rotary union ensures seamless operation of shipboard systems, from propulsion and steering to cargo handling and HVAC systems.

Available in multiple sizes and configurations, the Ship Pipeline Rotary Union can be tailored to your specific needs. Whether you require a single-passage union for basic fluid transfer or, alternatively, a multi-passage model for more complex systems, our product range reliably offers solutions for every application. Moreover, advanced bearing and seal options further enhance performance by minimizing friction and, consequently, extending service life.

Specially engineered for onboard piping systems, this high-precision component effectively facilitates the seamless flow of fluids such as seawater, hydraulic oil, and compressed air across rotating interfaces. Furthermore, whether you’re outfitting a commercial vessel, naval ship, or offshore platform, our marine-grade rotary unions consistently guarantee superior durability, exceptional corrosion resistance, and unmatched reliability under extreme conditions. In addition, their robust design ensures long-lasting performance even in the harshest maritime environments.

Key Features

Robust Marine-Grade Construction

Built from stainless steel, brass, and hard-anodized aluminum, our ship pipeline rotary unions resist saltwater corrosion, high pressure, and mechanical stress.

Multi-Channel Fluid Handling

Support for single or multi-passage configurations allows the simultaneous transfer of different media, ideal for cooling systems, ballast water operations, or deck machinery.

Precision Sealing Systems

Equipped with advanced sealing technologies, including carbon-graphite, ceramic, FKM (Viton®), or PTFE seals, these rotary unions not only minimize wear but also ensure long-term sealing integrity. Moreover, the combination of these high-quality materials significantly enhances durability and performance, thereby reducing maintenance requirements and operational downtime.

High-Pressure Capacity

Designed for pressures up to 6000 PSI, making it suitable for hydraulic winches, steering gear systems, and marine cranes.

360° Continuous Rotation

Enables unrestricted movement of pipelines or hoses connected to rotating drums or turrets—critical for dynamic marine applications.

Applications

Our ship pipeline rotary unions are widely used in:

⚓ Marine Deck Equipment

Commonly used in hose reels, winches, and rotating cranes, these rotary joints effectively enable a continuous fluid supply during deck operations. Additionally, their reliable performance helps maintain operational efficiency and safety in demanding maritime environments. Furthermore, by facilitating uninterrupted fluid flow, they contribute to smoother and more efficient handling of equipment on board.

🚢 Shipboard Hydraulic Systems

Facilitate efficient transfer of hydraulic oil or cooling water to actuators, rudder systems, and stabilizers across moving parts.

🛠 Offshore Drilling Platforms

Used in turret mooring systems and rotating fluid handling arms for crude oil or drilling mud transfer under continuous rotation.

🧯 Ballast Water Management

Allow automated ballast tank filling and emptying, integrating into pipelines that rotate with onboard machinery.

🌊 Desalination & Water Treatment

Support rotary spray systems and rotating filters within compact marine desalination plants.
