Roll-Kraft’s regional tube and pipe
and roll forming seminars exceed
expectations
ATTENDEES from all across the US and
Canada gathered in Mentor, Ohio to learn
from Roll-Kraft’s internationally recognised
tube and pipe and roll forming instructors
during day-long tube and pipe and roll
forming training sessions.
Robert A Sladky, vice-president of
tube mill engineering at Roll-Kraft, led
the sessions, along with technical sales
engineer, Bret Molnar; vice-president
of operations, Chuck Summerhill; and
director of product applications, Dave
Rostocil. The speakers covered the
important areas of mill integrity, alignment,
tooling design, proper setup, and trouble
shooting. A bonus presentation each day
on Finite Element Analysis software was
included in the sessions. The PowerPoint
presentations, combined with “follow
along” seminar guide books and
hands-on displays, resulted in
one of the most comprehensive
training programmes to date.
“The audience participation
was exceptionally interactive
throughout both programmes,”
Mr Sladky commented.
“Additionally, many new
companies that are looking to
enter into the tube and pipe
and roll form industries were
also present. This entry-level
interest, along with the high numbers of
attendees from established companies, is
good news for the industry.”
The mix of participants in attendance
included personnel from management,
engineering, and maintenance, as well as
operators and their helpers.
Each day was concluded with a tour
of Roll-Kraft’s state-of-the-art facility in
Mentor, Ohio.
Roll-Kraft also conducts on-site training
sessions at customer facilities, on their own
equipment. Visit Roll-Kraft’s website for

New pipeline weld integrity service
introduced
PIPELINE welds in the oil and gas industry
will be coming under increased scrutiny
after a new evaluation testing method was
designed by Exova.
The company has introduced a new
Immersion Ultrasonic Testing (IUT) technique
that has become part of the Automated
Ultrasonic Testing (AUT) validation procedure
for girth weld inspection, enhancing the
level of accuracy and reducing the cost of
production for pipelines.
The testing service is particularly relevant
for discovering smaller defects as a result of
the high accuracy robotics and enhanced
immersive testing environment.
An increased number of defects can be
identified because of the service, such as
cracking, porosity, incomplete penetration,
inclusions, lack of sidewall fusion, and
related defects that can compromise the
pipeline’s girth weld strength. Exova has
also invested in an innovative electrical
discharge machine which is capable
of producing minute slices of macro
specimens with a new stage of precision.
The perpendicularity of the specimen is
guaranteed and ensures no material will
be lost during machining.
Sander van Nieuwenhuijzen, operational
manager of Exova in The Netherlands, said:
“Due to the increased demands on pipeline
integrity, it is important that any defect in the
welds are detected, accurately located, sized
and reported quickly. Exova has actively
encouraged input from other industry leaders
on this service to ensure it will help improve the
sector’s reputation and production efficiency.
The new testing method offers better
inspection detection and sizing capabilities
helping non-destructive testing companies
to improve their probability of detection
and sizing accuracy, as extreme critical
analysis can be performed. This is crucial
for our clients, as we offer them enhanced
confidence that their pipeline welds are
free from critical defects.”
The testing regime was designed at
the Exova laboratory in Spijkenisse, The
Netherlands, but will be available to the
company’s clients throughout the world.
The Spijkenisse laboratory is one
of Exova’s leading materials testing
laboratories, offering chemical and corrosion
testing as well as failure analysis.
