Soluforce pipe to pipe connection concept

Every business needs the right connections. We therefore offer a wide range of fittings and connectors to ensure a safe and solid coupling – whether it’s to a SoluForce pipeline system or existing infrastructure.

The SoluForce inline coupler connects two lengths of SoluForce pipe. Using highly portable machinery, it requires only limited equipment on site to create a safe, fast and durable connection. Result: a maintenance-free system that has been proven over years of operation.

The SoluForce flanged fittings use the same equipment and deliver the same advantages. These fittings are used to connect to other standard pipeline components, such as valves and conventional steel pipe connections.

SoluForce fittings and connectors are easy to install and need only limited crew. Add in the long lengths of pipe and it’s easy to see why a SoluForce system can be deployed quickly and safely. Installations can be supported by a SoluForce technician or a local contractor can be trained to install the system.


Electrofusion inline couplings:

  • Fully non-metallic thanks to a combination of butt-welding and electrofusion
  • The installed coupling is designed to be stronger than the pipe itself

SoluForce pipe-to-pipe connector:

  • A 316L stainless steel connector with an electrofusion connection


Soluforce pipe to pipe connection concept in 8 steps

1. Reading the coupler data

Running the “bar code reader” over the barcode of the in-line coupler will identify the coupling and initiate the welding procedure. After the in-line coupler condition is tested by the CNC-unit the preparations can start.

2. Scraping the pipe surface

The pipe-end cover layers are scraped to get a fresh PE-surface to weld the in-line coupler electrofusion sleeve.

3. Loading pipe into the welding frame

The in-line electrofusion sleeve is cleaned and slid over one pipe-end. The pipe-end with the in-line coupler and the second pipe-end are loaded into the welding frame.

4. Trimming the pipe ends

By means of one of the trimming tools both pipe-end faces are trimmed resulting in a small length of free liner pipe necessary for butt-welding.


5. Butt-welding the liners

After removing the burrs a heating-plate is inserted for around 60 seconds to heat both pipe-ends.

6. Butt-weld cooling

The heating-plate is automatically removed and the pipe-ends pressed together. The butt-weld procedure is fully controlled by the CNC-unit.

7. Welding of the electrofusion sleeve

After a cooling time of approx. 8 minutes the in-line coupler electrofusion sleeve is slid back centrally on the butt-weld and fused to the pipe connection by energizing the copper heating-coil for about 4 minutes. When the electrofusion is finished the coupler must be cooled for about 30 minutes.

8. Cooling of the connection

After expiry of the cooling time, the welding parameters are checked by the CNC-unit. If the welding parameters are within the specifications, the connection is approved (“Parameters OK” is displayed). Now the pipe to pipe connection can be removed from the welding frame and the pipe put in place.
