Welding pipes
in a few minutes
Our patented Snapweld’ing is as easy as it can be!
This video explains Snapweld’ing in 90 seconds.
Snapweld’ing is no hard work
Traditional welding is physically very hard work as the welder lies on the ground several hours per day, constantly moving their hands intensively to creat the weld. Psycologically it is also straining due to the monotony of the work.
Consequently it gets more and more challenging to find qualified welders. Snapweld’ing on the other hand is no har work and requires just a short training session.
Snapweld’ing reduces costs and time schedule
Snapweld’ing is fast and easy. The time spent per joint is heavily reduced, saving direct work costs and machine costs for the supporting vehicles and machinery. No need for gas or electricity implies further cost reductions.
Less time per joint reduces the total project periode, causing shorter bloackage of streets, neighbourhoods etc. These indirect cost savings are quite considerable.
Trippel layer, reinforced weld
Traditional performed welds have been a key source to piping failures like cracking. The quality of the traditional weld is highly dependant on the qualification of each welder. Snapweld’ing isn’t, because it can hardly not be performed in a wrong way. Snapweld’ing creates a tripple layer reinforced weld
Thermite; power-powder
Thermite is a mix of iron oxide (Fe2O3 ) and alumium powder (Al). Igniting this mix, starts an extreme chemical reaction, reaching 2500 degrees in seconds. The aluminium connects to the oxygen in the iron oxide, creating iron and aluminium oxide:
* (By adding carbon to the process we get a carbon steel weld.)

District heating is the future
According to The Heat Roadmap Europe (which is funded by the EU’s research and innovation program), EU has a potential of reaching an overall district heating share of 50% of the total energy used for space heating and cooling by 2050. This is 5 times higher than todays 10%. To reach this 50% potential, an extreme construction of piping networks and heat sources is required. Consequently, development of district heating is very high on the agenda in most EU countries.
4th generation
district heating
4th generation district heating is a smart flexibel heating system that combines several renewable heating sourses in a smart-grid. Heating pumps, access heat, thermal heat, biomass, solar and wind are common sources of reneable energy used for district heating.
By using a smart-grid the temperature in the grid can be lower than in previous 3rd generation networks.
The most populated contries will lead the way
Population, access to renewable energy sources and governmental focus are the three key drivers of district heating developement.
Not suprisingly the largest and most industrilized coutries in Europe has the highest expected growth in district heating towards 2050.
These numbers are estimates done by Heat Roadmap Europe, funded by the EU.
Steel pipes vs polymer pipes
Polymer pipes in district heating has become very popular for the smaller sized piping (up to 100 mm carrier pipe diameter). Typically from the street and into buildings.
Delivery on rolls, quick installation and low weight are KPI’s for polymer piping.
But the polymer’s limitations in temperature, preassure and lifespan makes steel piping the preferred matherial for network piping (in most situastions).
About Snapwelder
Snapwelder was founded in Bergen, Norway in 2016, with a vision to adapt thermite welding to steel pipes.
After achieving patent protection in 2019, Snapwelder started focusing on district heating steel pipes, as district heating is a key pilar for future space heating and cooling. Snapwelder is currently working on qualification of the technology with DNVGL.
Snapwelder’s head office is still in Bergen, Norway and sales and marketing in located in the Netherlands.
