Swivel joints are flexible piping components or piping couplings made of steel, stainless steel or other materials needed in a wide range of industrial applications where

  • flexible piping systems have to transfer powder and granules, gases and liquids;
  • gases and liquids have to be injected into rotating plant components;
  • hose connections have to be balanced from stress caused by bending or torsion forces or replaced by swivel joint scissors;
  • swivel joint scissors are applied because of extreme plant specifications and/or raised security requirements.

Swivel Joints are applied in the following industrial areas and applications:  

  • Chemical and petrochemical industry
  • Pharmaceutical industry
  • Food industry
  • Power plants
  • Water preparation and municipal technology
  • Test stands
  • Cooling water supply
  • Hydraulic systems and pneumatics

Swivel Joints in 8 different styles

Swivel Joints are available in 8 different styles (10, 11, 12, 20, 21, 22, 30 und 31) combinable with 3 types of connecting ends (threaded, flanged and welding ends). Appropriate combination of these styles may realize almost every 3 dimensional movement.

Coming up to these and other requirements our customers select from the following choice of Swivel Joints: 

Swivel Joint Type W

Type W is our standard swivel joint.
It is equipped with a radial sealing.
The bearing has 2 marble runs for application with high outside forces or moments or very high pressures. The standard bullets are made of stainless steel.
It serves as base for customer-specific applications like operating pressures up to 1 000 bar or high-temperature applications of low-pressure range up to vacuum range (exhaust from combustion processes) or liquefied gas applications like LPG, etc.

There can be used for a variety of fluids. Our customers select the materials for cabinets, sealings and bearings according to the specification.

Such connections as pipe nozzles or pipe elbows, threads and flanges are available. Customer-specific connections can be installed alternatively.

Nominal diameter:1" / DN25 to 28" / DN700 [up to 40" / DN1000 on request]
Working pressure Pmax:vacuum up to 6.000 psi / 420 bar *
Working temp. Tmin/max:-67°F to 482°F / -55°C to 250°C *

* Pmax and Tmax may not occur at the same time

VdS-certification (for use in fire-extinguishing systems, e.g. in high bay warehouses.)

Swivel Joint Type LW

Type LW is the “light” version of the type W for application under low and medium pressures or for low outside forces or moments. Therefore the bearing has only one bearing track.

It is identical in construction as type W.

Nominal diameter:1" / DN25 to 28" / DN700 [up to 40" / DN1000 on request]
Working pressure Pmax:vacuum up to 1.450 psi / 100 bar  *
Working temp. Tmin/max:-67°F to 482°F / -55°C to 250°C *

* Pmax and Tmax may not occur at the same time

Swivel Joint Type T

Type T is our standard swivel joint for hydraulic applications with threads connectors.  
It is radially sealed and has a bearing with 2 bearing tracks.
Some different threads can be mounted, such as aG1/2" combined with iG3/4".
Construction forms 10, 11, and 12 can also be applied on the flexible pipings with narrow installation dimensions.

It could be modified according to the customer specifications. Accordingly, there are a wide range of materials for housing and sealings.

Nominal diameter:G¼" to G2"  [alternatively NPT]
Working pressure Pmax:vacuum up to 6.000 psi / 420 bar    *
Working temp. Tmin/max:-67°F to 482°F / -55°C to 250°C *

* Pmax and Tmax may not occur at the same time

Swivel Joint Type LT

Type LT is the “light” version of the type T for application under low and medium pressures or for low outside forces or moments. Because of it the bearing has only one bearing track.

It is identical in construction as type T.

Nominal diameter:G¼" to G2"  [alternatively NPT]
Working pressure Pmax:vacuum up to 1.450 psi / 420 bar *
Working temp. Tmin/max:-67°F to 482°F / -55°C to 250°C *

* Pmax and Tmax may not occur at the same time

Swivel Joint Type V

Nominal diameter:¼" / DN8 to 1½" / DN40
Working pressure Pmax:vacuum up to 6.000 psi / 420 bar *
Working temp. Tmin/max:-67°F to 482°F / -55°C to 250°C *

Swivel Joints Type V are designed as straight union and 90° elbow union,
with male (N), female (S) threaded ends and as olive type tube fitting (C) with 24° sealing cone.

(N)male threaded(S)female threaded(C)

Swivel Joint Type LA for Loading Arms

Type LA is our standard swivel joint for use in loading arms on the ships, tanker trains, and fuel tank trucks.

The swivel joint is sealed radially.
The seal is designed with redundancy and has additionally an O-Ring between medium’s sealing and bearing.
The bearing is designed with 2 bearing tracks that are dimensioned for operation pressure of 160 bar. This leads to the very long life.
The housing consists of three parts that make it easy to change a seal without having to completely dismantle the loading arm.

Nominal diameter:

1" / DN25 to 10" / DN250 [larger on request]
Working pressure Pmax:vacuum up to 580 psi / 40 bar *
