The Future of pipe welding for high pressure pipes
Easy-to-Fit pipe beveling makes weld prep easy
Nowadays Pipe welding is still a job for well skilled specialists. To adjust the pipe, to make a good weld preparation and finally to achieve a perfect weld seam for the pipe junction in terms of quality is a sophisticated challenge.
Especially for high pressure pipes, even if these specialists are available, it is a complicate, time consuming and expansive operation. For high wall-thickness pipe still mistakes can happen to specialists and create a lot of additional work in the factory or on-site.
Easy to fit is the new welding solution for pipes and fittings, which enables considerable savings throughout the supply chain and can thereby boost the profit in the pipe welding process. The idea of this pipe prepping system has been developed by Erne Fittings in Austria for fitting solutions. In cooperation with DWT in Germany the perfect tools for portable pipe beveling machines have been developed.
Scientific research by the German University in Chemnitz and by the government welding institute SLV Halle confirm, that the properties of the Easy-to-Fit weld seam are equivalent to or even better than conventional V-welds. Either for automated welding or manual pipe welding the system is simply perfect and the gap-free root can easily be TIG welded.
The first connection which saves more money than it costs.
Easy-to-Fit is a small investment in an intelligent pipe prepping system which ensures greater efficiency, profitability and indeed process stability. Especially for automatic pipe welding the weld end preparation is very complex. The welded joints require a weld gap with very narrow margins. Also the misalignment between root faces must be reduced to a minimum. This requires major effort to adjust and position parts as the margins allowed by the standards are so large that there is always misalignment. But also for manual pipe welding the system creates huge benefits.
Easy to fit means "ready to weld", no matter whether you weld automated or manually and depending on the process up to 50% savings are possible:
ADVANTAGES:
• Reduction of the total cost of producing a weld seam
• No more alignment, pipes are “ready to weld”,
• Can be repeated reliable for process stability
• Welding material is saved
• Perfect welding work regardless of employees' qualifications
Innovations like Easy-to-Fit can only be achieved with close end user contacts and an in-depth understanding of the corresponding application. Together with an Austrian customer who was prepared to take a revolutionary path from the beginning, the innovation was created. Nowadays many DWT customers use this brilliant system with big benefits and increase their competitiveness.
Users comment:
“Easy-to-fit” is the perfect solution for us. Thanks to easy to fit, we have been able to significantly increase process stability and productivity. The weld end preparation is so exact that we can weld twice as many pipes or fittings in the same time as before, and in doing so achieve the highest quality standards. Easy-to-fit offers a crucial competitive advantage.”
DWT Germany is manufacturer of high quality pipe beveling machines, made in Germany and exporting to 30 countries worldwide. In cooperation with Erne Fittings, Austria, the company has developed special machines and tools for the Easy-to-Fit solution for fittings and also for single pipe applications.
“This innovation is a break-through in pipe welding process and will have a high influence on quality and productivity in heavy wall pipe welding” says Michael Weymann, managing director of DWT GmbH Germany.
On the international nuclear show WNE 2016 in Paris / France Easy-to-Fit will be presented with life demos on our booth in hall 2B/N60.
