GS Retain Ring

​GS Hydro is the manufacturer in supplying non-welded technology which allows pipes to connect without any welding required. It is an innovation for retain ring in pipe connecting system to allow piping systems with high working pressure up to 690 bar.

The pipe outer diameter is available between 39mm to 350mm and it can be assembled in systems without the use welding connection. The retain ring system provides an easy and fast method to connect pipes with completely leak-free high levels of joint integrity in the most cost efficient and job effective manner.

What are retain ring

​1. What is retain ring?
The retain ring system is used in a huge range of high pressure applications in a wide variety of industries ranging from pulp & paper, metals and mining, marine and offshore, sugar and testing. It is suitable to use in hydraulic system application, lubrication, hydro carbon, high pressure air and water cleaning lines, mud cement as well as other pipeline systems where high system integrity, fast installation times and inherent cleanliness are important.

GS Hydro Retain Ring
The retain ring system has a maximum allowable pressure that can withstand up to 420 bar in piping system. The retain ring system can be used with working pressure as high as 690 bar under specific piping applications. ​

​Extensive testing has shown that retain ring system application is used for high pressure piping system with a wide range of different materials. The retain ring system includes a wide range of flanged types which is 3-way tees, elbows or threaded adaptors.  A standard bonded seal is used whereas a fire-safe seal is used for process piping in hydraulic application.

3. Pipe end preparation & assembly ​
The retain ring system is installation flexible, inherently clean, highly reliable and cost-efficient. It is fast and easy to prefabricate, assemble and install. A groove is made on the pipe and the pipe end itself is machined when preparing a retain ring connection. 

A retain ring is installed into the groove before the flanges are placed onto the pipe end connection. A seal is positioned in between the flanges and pipe ends for tightening purpose. Fabrication of groove is flexible and it can either be prefabricated in workshops or on site installation.

4. What is the operating principle of retain ring? 

Retain ring holds the flanges to the pipe. Retain ring is a stainless steel ring or spring that sits in a machined groove on the pipe end connection. 

The retain ring connection features are as follow: 
  • Pipe ends are pre-worked with groove available 
  • Between the pipe ends, there is a seal placing
  • A flange is fitted onto the pipe end connection
  • A flexible retain ring is stretched over and into the groove of connection
  • The flange screws and washers are tightened
​
The pipe ends are pressed against the seal to each other during assembly and the tightening of bolts. The retain ring creates a tightness assembly while flanges and screws absorb the axial force and shock. While the retain ring and flange of the pipe is combined, it creates a stronger connection than pipe itself.
