Swivel Joint 2815 Series, Carbon Steel with a Stainless Steel Liner

The Swivel Joint 2815 series is a three piece split flange design like EWFM’s Swivel Joint 2833 series. Only available in Carbon Steel, its main advantage over the 2833 is its Stainless Steel 316L liner. This in turn means the Swivel has the strength of a Carbon Steel swivel, however can cater for more aggressive media as well as hygienic media. The difference between the two is that the 2815 series is only available in carbon steel. The main advantage that this swivel joint has is its stainless steel 316L liner which means that it has strength of a carbon steel swivel, but it can cater for more aggressive media because of the liner. This means that it is suitable for unsupported loads and large range of chemicals, foods, and beverages.

The three-piece design allows for a quick and easy primary seal which without the process of removing the ball bearings. The Swivel Joint 2815 series can be supplied individually or fabricated with elbows and end fittings that can be manufactured in a range of styles.

The Swivel is therefore suitable for unsupported loads, a large range of chemicals, foods, beverages and much more. The three piece design allows a quick and easy primary seal change without having to remove ball bearings. If you are looking for a strong cost effective Swivel that can cater for a large range of media then the model 2815 Swivel joint is for you.

Applications

• Loading arms.
• Piping systems.
• Food duty systems.
• Chemical systems.

Pearl Swivel Joints are used when compressed or decompressed (below atmospheric pressure) fluid/gas is transported and the piping needs to be rotated or moved in optional direction of up/down, left/right, or forward/backward. Movable pipeline can be made easily, safely and at a low cost, and piping can be secured. These Swivel Joints can be rotated 360 degrees. They have large mechanical strength that endures large radial/thrust load and moment load due to double-row ball bearings and grease lubrication. Since a ring-type packing such as O-ring is used in the sealing section, the structure remains simple while providing stable sealing that does not leak any pressurized fluid contained. PK series, for high temperature application is incorporated with lubrication-free bearings section, and the sealing section adopts PTFE material and the mechanical seal to provide stable sealing.

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.
