Large Bore Swivel Joints play an important role in fluid transfer systems involving large-diameter pipework. They allow controlled rotation while helping reduce stress on connected equipment.
At EWFM, we supply a wide range of Large Bore Swivel Joints for demanding industrial applications. These include Marine Loading Arms, Floating Suction Units, Hose Reels and articulated pipework.
With various sizes, materials and configurations available, we can help customers find a suitable solution for their operating requirements.
What Are the Benefits of Large Bore Swivel Joints?
Large Bore Swivel Joints provide 360° rotation within large-scale piping systems. Their bearing arrangements help support external loads while allowing connected equipment to move smoothly.
Depending on the application, the design can incorporate one or two rows of ball bearings. This provides flexibility when selecting a joint for different operating conditions.
Other benefits include:
- Flexible configurations: A range of styles, elbows and end connections can suit different installations.
- Material options: Carbon Steel, Stainless Steel and Duplex Steel are available, alongside specialist materials.
- Reliable rotation: Ball-bearing arrangements allow movement while supporting the loads within the system.
- Maintenance considerations: Seal arrangements can support servicing and maintenance, depending on the selected design.
Large Bore Swivel Joint Specifications
Our current Large Bore Swivel Joint range offers several options to suit different applications.

The final specification will depend on the operating pressure, temperature, media and external loads.
For applications involving unusual conditions or specialist requirements, we can review the design on a project-by-project basis.
Where Are Large Bore Swivel Joints Used?
Marine Loading Arms
Marine Loading Arms transfer liquids and gases between ships and shore-based facilities.
Swivel Joints allow the arm to articulate and move into position. They also accommodate movement during transfer operations, helping reduce stress on the connected pipework.
Large Bore Swivel Joints are particularly useful where the system requires greater flow capacity and larger pipe diameters.
EWFM has previously supplied 20″ Swivel Joints for Marine Loading Arm applications.
Floating Suction Units
Floating Suction Units draw liquid from near the surface of a storage tank. This helps reduce the intake of settled contaminants from the bottom of the tank.
As the liquid level changes, the Floating Suction Unit must move with it.
A Swivel Joint allows the suction arm to rise and fall while maintaining a sealed connection to the fixed pipework.
Large Bore Swivel Joints are well suited to these applications, particularly where the system handles high flow rates.
Style 40 is one configuration commonly used for Floating Suction Units, although the final arrangement depends on the tank and system design.
Hose Reels and Articulated Pipework
Large Bore Swivel Joints also support Hose Reel systems and articulated pipework.
They allow rotational movement while helping prevent excessive stress on hoses and connected equipment.
This is particularly important in installations that require regular movement or repositioning during operation.
Choosing the Right Large Bore Swivel Joint
Selecting the correct Large Bore Swivel Joint involves more than choosing the required diameter.
The media, operating pressure, temperature and external loads all influence the final specification. Material compatibility and the available installation space are also important.
Customers should also consider the required movement, end connections and any specific maintenance requirements.
Our team can review these details and help identify a suitable design for the application.
