DWT Germany is manufacturer of professional pipe beveling and cutting machines for weld preparation of pipe welding in heavy duty industry. The head office is located in Germany and branches are available in 35 countries worldwide. DWT Germany is license manufacturer under brand name BABCOCK for many years, who developed this equipment with their own on-site knowledge as enduser. Especially for water wall boilers and heavy duty pipes in oil and gas business DWT offers very special products for on-site operations with flexible and low weight machines. Their high working speed and quick readiness for use allow economic manufacture.
In practice it has been proved that weld preparation of tube ends influences in a high degree the quality of the welding junction. For welding applications of tubes with a high wall-thickness and for orbital welding technology the welding engineer requires nowadays a perfect and effective weld preparation by use of mechanized weld preparation. We provide the solution with reliable and long life equipment made in Germany.
pipe beveling machine
The pipe beveling machine is used to bevel welding edges on heavy wall single pipe, water wall boiler panel and headers. For industrial steam boilers it is used for beveling tube walls and cutting out welds. Having a low weight and operated by one man only, it is well suited for use in workshop and on site. Due to its extremely compact type of construction it can be used in confined space. The machine provides high working speed and effective use of consumables for economical manufacturing.
pipe cutting machine
Portable clamshell pipe cold cutting machines for cold beveling and cold cutting operations of pipes on-site, are versatile in application and can perform many operations. The machines are reduced in weight and dimensioning. The accessories needed for the different machining are interchangeable and allow multiple operations, like beveling and cutting in one operation, inside beveling, flange repair of flange facing.
Internal line up pipe welding clamp
The welding quality in pipeline construction is crucial and has to fullfil worldwide standards, certified by international authorities. Companies like Norske Veritas have set up guidelines, to avoid defects. Very important is the choice of the correct internal line-up pipe welding clamp for weld preparation, to compensate tolerances of pipe manufacturers and to avoid edge misalignment during pipe welding process.
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.
