HOUSTON German forging, extrusion and ring rolling
company Otto Fuchs KG is partnering with TPS Technitube
Röhrenwerke GmbH (TPS) to enter the aluminum drill pipe
Based on some very special extrusion technologies, Otto
Fuchs is able to produce high-strength seamless tubes with
very special dimensional features, which enable
ustogether with our partner company, Technitubeto
produce aluminum drill pipes, Bernd Velten, head of
technical sales and marketing at Otto Fuchs, told
AMM on the sidelines of this weeks Offshore
Technology Conference (OTC) in Houston.
Velten noted that aluminum pipes have some considerable
advantages over conventional carbon steel. The major
advantage, of course, is the lower weight of the pipe, which
allows the user of it to drill deeper (and) handle longer
pipes with existing equipment. Also, for directive
(drilling), the higher elasticity of aluminum offers
considerable advantages, Velten said.
The company is initially focusing on the Asian, Russian and
American markets where aluminum drill pipe has already found
some acceptance. Otto Fuchs has seen little interest in
Europe so far, Velten said.
The Meinerzhagen, Germany-based company is manufacturing the
alloys and providing the extrusions for the pipes, which will
primarily use 2000- and 7000-series aluminum. Meanwhile,
Daun, Germany-based TPS will be responsible for threading and
finishing, Velten said.
Otto Fuchs experience with strict quality rules and
regulations in making aluminum alloys and extrusions for the
aircraft industry should serve it well in the drill pipe
market, according to Velten. The same (quality)
philosophy is required in ... drilling technology, he
Otto Fuchs extrusion technology allows for varying
thicknesses throughout a tube, making it possible to increase
wall thickness at the ends for easier threading, he said. The
technology also allows Otto Fuchs to extrude pipes with a
flange at the end, eliminating the need to bolt on or weld a
flange, Velten said.
