Rotary Unions | Swivel Joints

Steam, Water, Air, Hydraulic, Hot oil, Sour Gas, Coolant, MQL Media

Rotary joints, rotary couplings are used to transfer media from stationary source to rotating machinery. Applications include the transfer of steam, water, hydraulic fluid, thermal oil, glycol, coolant, air. LPR’s rotary unions are used for various industries such as oil&gas, chemical, paper, agriculture, automotive, machine tool, rubber & plastic, food, tire applications.

 

Rotary unions from 1/8’’ to large high performance models with silicon-carbide, spherical, or mechanical sealing options are available.

 

Swivel joints for a broad range of uses in the shipbuilding, marine, chemical, petroleum, refining, mining, distilling, brewing, ink and paint industries. We offer various types of seals, including bellows mechanical sealspherical o-ringflange, and balanced sealing options.

 

Our rotary unions and swivel joints meet the highest demands of our clients and industry standards such as ABS, DNV, DNV welding standards, and DHV high pressure.

Rotary Unions | Swivel Joints Overview

Rotary unions are used to transfer media from stationary source to rotating machinery. Swivel joints are used for connecting fixed pipe with rotating pipe, fixed pipe with linear action pipe, and linear action pipe and rotating pipe. Typical transfer media for rotary unions and swivel joints includes water, air, hydraulic oil, steam, hot oil, sour gas, coolant, MQL, and various other media.

 

Rotary unions and swivel joints are produced in South Korea at an ISO9001 certified facility and are designed to meet ABS, DNV, DHV high pressure, DNV welding standards.

 

Current clients include Daewoo Shipbuilding & Marine Engineering, Samsung Heavy Industries, Hyundai Heavy Industries, POSCO Steel, NEXTEEL, DSME, TSC Group, LG, NEXEN Tire, KIA Motors.

Rotary Unions | Overview

Rotary unions are used to transfer liquids, air, and gases while rotating or swiveling from a stationary source to and from rotating machinery. Whether you require a single passage or multiple passage rotary joint, we are able to supply standard and custom-made rotary unions for your specific application.

 

The advantage of a multiple port rotary union is to have an option to transfer more than one type of fluid medium through a single rotary coupling.

 

Some of the applications that we cover are rotary unions for tooling machine, automotive jigs, industrial machinery, and industrial plants. Typical fluid transfer media includes coolant, hot oil, steam, hydraulic oil, air, and cutting oil.

 

Sealing options include silicon-carbide, spherical, mechanical, and balanced sealing options. Using a balanced seal guarantees low friction during high speed rotation and high pressure operations which makes this type of seal ideal for offshore, chemical, and marine applications.

 

We supply a wide series of rotary joints specifically designed for high speed, high pressure, and high or low temperature operation. Customized extra high pressure models for hydraulic expanding shaft rotary joints and high pressure rotary unions for pressure over 15,000 PSI are also available.

Swivel Joints | Products

Swivel joints are used to connect fixed or stationary parts to other rotating parts or angled hoses. We offer 10 series of swivel joints designed for various media, pressure, and different industries ranging from chemical, food, wastewater treatmentoffshore, marine, to general metal.
