Work smart with the Liqway method,
the easy way to get a dry and reliable weld.
Water left in the pipes makes it difficult to repair and maintain local district heating networks. A slow drain or leaking valve can turn professional welding work into waiting times, delays and emergency solutions. After another late night on an assignment, we got an idea.
The result was the Liqway method, which replaces opening welding and other improvised solutions. With our suction nozzles, you quickly lead the water away through the pipe joint. The design is approved by both DEKRA and Kiwa and is used by, among others, E.ON, Stockholm Exergi and Vattenfall.
The easy way to get dry, reliable welds
With the Liqway method, you are always ready to solve drainage problems. The operation does not have to shut down unnecessarily, the subscribers get the heating facilities back faster, district heating operators save maintenance costs and employees can return home on time.
Instead you can subscribe to a set with a smart adapter and five suction nozzles for Euro 69 a month, without a lock-in period. The adapter registers every single use when you use a nozzle and help you invoice the cost further.
Our smart adapter automatically produces invoicing data that makes the savings worthwhile, both for you and the local district local district heating operator.
Dry welding zone without hassle.
Drain the water via the pipe joint.
Use our suction nozzles to divert water away from the weld zone without damaging the pipe. Liqway Flex fits pipes from DN200 to DN700.
Liqway Hi-Temp are adapted for smaller pipes and require a cut in the pipe some distance away. This method withstands gas welding and is available as standard from DN32 to DN150. Can also be used on twin tubes.
”We saved a four-hour break next to a maintenance job on a DN250 local district heating line. Using the Liqway method, we did not need to expand the shutdown area. ”

”When connecting a local district heating line DN300, water was still leaking. We used the Liqway method instead of open welding which should be avoided”

”We did not have to extend the interruption or make extra interventions on the pipeline, which meant that we saved 55 hours in labour costs while at the same time getting higher quality and service life in our distribution networks”

The Liqway method was developed by Martin and Isak Werme, third generation pipe contractors. After another late night, we began to think: What if it was possible to divert water directly via the pipe joint? We solved a problem that no one else has done anything about since Grandpa’s time, making work faster and safer.
