Swivel Joints

Single Raceway Swivel Joint – D0002

The D0002 Swivel Joint forms the basis for our swivel joints with one ball track. It has a minimal structural length, minimal external diameter, and minimal weight.

The internal flange makes it possible to change the seal without removing the swivel joint from the pipeline. The D0002 Swivel Joint can be relubricated via grease nipples. If required, the balls can be removed and replaced by first removing the ball track plug.

Swivel Joint for Chemical Industry – D2000

The use of our multifunctional swivel joint – D2000 – optimizes nearly all liquid transports.

Whether in the mineral oil, food, or chemical industry, the D2000 meets the highest standards.  Multiple variants allow the customer to configure to meet their own specific requirements.  Due to the sandwich design, the bearing module is separated from the product-carrying components. It can therefore be used as a standard swivel joint for nearly all media with temperatures ranging from -50 °C to +250 °C with a max operating pressure of 580 psi (40 bar).

Swivel Joint – D1133

The D1133 swivel joint is a variant of the basic D0002. It is the ideal swivel joint for nearly all applications in the chemical industry. It has a minimal structural length, minimal external diameter, and minimal weight.

In the D1133 swivel joint, the ball track is encapsulated by two O-rings, neither dirt from the outside nor product from within (in case of leakage) can reach the ball track. Should the main seal fail, leakage is indicated through the leak detection ports

PTFE Lined Swivel Joint

D2000 – PTFE Swivel Joint is a variant of the basic form. It is internally lined with PTFE and is equipped with a special seal, making it suitable for extremely aggressive products.

Double Raceway Swivel Joint

The D1010 is the standard swivel joint with two ball tracks. It is usually used where large size swivel joints have to take heavy loads (typically for Emco Wheaton Marine Loading Arms). Both ball tracks of the carbon steel version are hardened and polished, giving the swivel joint a high degree of load capacity and long service life, even under extreme loads.

OPW Engineered Systems’ fabricated and cast ball bearing swivel joints allow you to construct a metal piping system that permits easy movement in any direction. Moveable, flexible and reliable, OPW Engineered Systems’ swivels are designed and built to the highest quality standards, including precision machining and 100% penetration welding, with special design features that include:

1. Tight Seals

• O-Rings provide a tight seal without hindering swivel action
• Accurately machined and micro-finished grooves provide for minimal seal wear
• Available in Buna-N, Viton®, EPT, Neoprene, Kalrez® and other seal materials
• Teflon® seals are available as spring energized or silcone/Viton® encapsulated

2. True Ball Bearing Race Alignment

• Body and tail sections are locked together by a double row of ball bearings
• Raceways are machined to precise tolerances
• Double raceway design assures proper alignment and prevents binding caused by temperature changes and heavy radial loads
• Carbon steel swivels have hardened races to maximize load-carrying capability
• Ball bearings are hardened, precision-ground steel
• Stainless steel swivels have stainless steel bearings
• All OPW swivels are available with stainless steel bearings on special order

3. Protected Bearing Chamber

• Protective inner O-ring seal prevents product from entering bearing chamber
• Outer seal keeps rain, dirt, and other contaminants out
• Both seals hold in lubrication

4. No Field Adjustment Necessary

• Balls are held in place by factory-installed plugs that never need to be adjusted to maintain bearing performance

5. Easy Lubrication

• All OPW swivels are pre-lubricated at the factory
• All 3/4″, 1″, and submerged swivels are permanently lubricated
• A grease fitting between races that accepts a standard grease gun is available for swivels that require field lubrication
• Non-lubricated swivels are available on special order
