Designing for the Deep using Subsea Swivels:

High pressure rotation without leakage is a challenge…

Swivel Joints also known as Rotary Unions provide vital movement to a vast array of industrial equipment. From excavators to subsea control lines or even your garden hose, swivel joints. can be found at the heart of the system and are fundamental for the most basic operations. This wide range of uses and differing applications requires a wide range of efficient designs. That’s why Rotaflow offer a bespoke design and manufacture service: Swivel joints tailored for each unique requirement, optimising space and seal life.

Rotaflow have much experience in the design of multiports for umbilical reelers. In the past we have been asked to re-design a solution for better performance on deep water hose reelers. The previous design, not ours, was not providing the performance required. After design and testing we were able to provide a solution. This particular design is still in operation on several reelers today.

With 40 years of experience Rotaflow have become known throughout the industry for durable reliable products.

There are many different forms of Swivel Joint… from very straight forward designs of our F and FS series, Compact swivels, or Heavy Duty to Articulated Pipework configurations, Floating Suction Arms, Jacketed, High pressure.

A Swivel Joint reduces costs by reducing the risk of leakage with its associated downtime.

By fitting a quality designed swivel, you are improving your production capacity.

We manufacture in Carbon Steel and 316 SS with “specials” in any grade of metal to suit customer specification: Titanium, Super Duplex, etc. With bores ranging from 0.25" to 40"; Vacuum duty to 20,000PSI and multi passaged designs allowing multiple flows of fluid though a single unit. We are specialists in taking your bespoke requirements and being able to design a solution that can fit your budget, dimensions, materials, FAT/ witness testing; hygienic and pressurised environments. We regularly test to Hyperbaric, Seal Life and conduct Temperature/Pressure/Load Cycle Testing. We are ISO 9001:2015 certified.
