Swivel Joint 2833 Series, Stainless Steel, Carbon Steel and Heavy Duty

A three piece split flange design, EWFM’s Swivel Joint 2833 series. The three piece design allows a quick and easy primary seal change without having to remove ball bearings. As a result, this is the main advantage over the model 2175 series. The swivel joint is currently being used in many applications in the oil & gas, chemical and food industries. Furthermore, to suit the requirement, model 2833 series swivel joints can be customised. Some examples include high or low temperatures and food grade. Due to the reliability of this swivel joint, EWFM use the model 2833 series swivel in other products such as loading arms and floating suction units.

The Swivel Joint 2833 series is a three-piece split flange design. Unlike most other swivel joint designs, this allows for a quick seal change without having to remove any of the ball bearings. This is what gives it an advantage over of the Swivel Joint 2175 series. These types of swivels come in a range of materials.

Our main offerings include, stainless steel, carbon steel, carbon steel with stainless steel lining, hardened carbon steel and hardened carbon steel with stainless steel lining. The hardening process allows for the swivel to handle more increased loads. In regard to the stainless-steel lining, this is included for projects where the carbon steel is not compliant with the media.

In the past, this type of swivel has been used in various industries such as oil & gas, food & drink and chemical. However, due to the range of customisation, it has the ability to cater for many more.

Unlike the Swivel Joint 2175 Series, 2833 is also available in a heavy-duty alternative, constructed in hardened Carbon Steel. The Model 2833 Series is also available with Stainless Steel lining for projects where Carbon Steel is not compliant with the media.

What Are Swivel Joints Used For?

Swivel joints are precision machined components that are used to connect and prevent bends in stationary loading hoses that can reduce flow, tear, or rip, releasing harmful chemicals into the air. Also known as rotating pipe joints, swivel joints that rotate on ball bearings can provide many planes of rotation and stress relief to a product line; whether it is a loading arm, pipe, or hose.

Swivels create a rotary mechanical and hydraulic linkage between stationary pipes, hoses, and other components of fluid transfer systems. They absorb shock, eliminate hose twisting and kinking, and allow for independent movement while fluids are pumped under pressure.

Swivel joints prevent kinks that form in hoses when one end of the hose rotates opposite the other end. Hose kinking reduces flow, increases system pressure, and causes fatigue of hose walls, crimps, and end connectors. Over time, higher pressures and worn-out hoses increase the probability of unexpected system failures and the release of potentially hazardous chemicals.

Where Are Swivels Used?

Dixon swivel joints can be found in product blending plants, liquid, and dry bulk transfer terminals, and in transport trucks designed to carry petroleum and other liquids from bulk terminals to distant delivery sites. Additional industries range from petroleum and petrochemical plants to refining, mining, distilling, paint manufacturing, irrigation, fertilizing, and food and beverage processing. Larger diameter swivel joints can be found in steel mills, water treatment plants, and marine terminals where they are used for loading and discharging cargo, and for loading propulsion fuel onto vessels – a process known as bunkering.

If an industrial operation involves pumping a fluid from a moving component to a stationary component, chances are good that a swivel joint has been installed to extend the life of the system and reduce costly maintenance and downtime.

Types of Swivel Joints

Swivel joints can be categorized based on various parameters as mentioned below:

Depending on the end connection, there are three types of swivel joints

Flanged swivel joint
Threaded swivel joint, and
Welded swivel joint.

Depending on the working component parts, swivel joints can be of three types:

Compact O-ring swivel joints that use an o-ring for pressure seal.
V-ring swivel joints that use a triple v-ring packing for sealing. They are robust in construction and suitable for severe applications.
Split Flange swivel joints that use a separate bearing pack design with an H-ring and two O-rings.

Depending on the flow paths, there are basically three types of swivel joints:

Straight through swivel joints having coaxial flow path.
Right-angle swivel joints having outlet ports perpendicular to inlet ports.
Offset swivel joints are a combination of both of the above designs
