Jansen uses state-of-the-art, high
performance machines to produce
welded, cold-rolled and drawn precision
and formed steel tubes made of various
qualities of steel.
The company’s advantage lies in
the development and production of
customer-specific steel tubes. In close
collaboration with customers and
with select material suppliers, Jansen
specialists develop solutions for
specific applications. The company’s
own process development and tool
making facilities allow rapid and flexible
reaction times, even at the prototyping
stage.
The drawing process allows production
of special sizes and forms at economical
conditions beginning at only 500m.
Significant customers include the
automotive and furniture industries, but
the precision steel tubes are also used
in the machine industry, for radiators
and cooling aggregates. The company’s sites in Oberriet,
Switzerland and Dingelstädt, Germany
can process high strength steels with
tensile strengths up to 1,000N/mm2 and
tubes with special ratios of diameter to
wall (from 6:1 to 60:1).
Computer-aided monitoring of relevant
processes and continuous testing
ensure consistent quality.
The services Jansen offers are
supplementedby variouspre-processing
and individual logistics services.
Depending on requirements, the tubes
are cut to size, de-burred, chamfered,
washed or annealed in Jansen’s own
plant.

CRC-Evans Automatic Welding has
launched a new dual-torch external
automatic welding machine for small-
diameter offshore and spoolbase
applications. The P625 offers leading-
edge technology and outstanding weld
quality in a compact machine that brings
high productivity to offshore jobs.
The P625 is fully digital, with through-
the-arc tracking and pulse MIG to
maximise speed and produce high
quality welds. Computerised monitoring
and control keep the torch and bead in
perfect position, removing the chance
of human error in the welding process.
From pre-weld programming to real-time
operation and post-project assessment,
digital technology takes care of accuracy
and repeatable performance.

The P625 allows software to be
upgraded in the field, so that changes
in weld parameters can be made on the
fly, getting the machine back to work
quickly. In the office, a PDA user can
program parameters and then download
them wirelessly to the P625, or data can
be uploaded to a PDA in the field and
taken back to the office for analysis and
reporting.
The P625 is also designed with scalable
architecture that will accommodate
future innovations, so it can be updated
with the latest technology.
CRC-Evans Automatic Welding designs
and builds the automatic welding
systems for land and offshore pipeline
construction. In addition to renting and
selling these systems to contractors on
a project basis, the division provides
other specialised services such as
engineering, on-site technicians, and
training. The company is a subsidiary
of CRC-Evans Pipeline International,
a provider of specialised equipment
and services for the construction of
pipelines.
CRC-Evans manufactures pipeline
construction equipment and automatic
welding systems, and provides
managed subsea services, field joint
coating, weighting, heat treatment, and
inspection services.
