Solutions for tube checking
PRODIM International is a manufacturer
of 2D and 3D portable measuring
devices and associated measurement
solutions. The company closely follows
developments in the industry and listens
to the users of the Proliner measuring
devices, which allows it to keep
improving the measuring devices and
developing new solutions for several
industries.
Whether manufacturers of bent tubes
and pipes want to check products upon
arrival, on the roller machine, or after
manufacturing, it is very important to get
the desired data quickly and accurately.
To get the outline measurements of
bent tubes and pipes has always been
very difficult. Because of the form of
the tubes, accurate measurement
of the angles or radius of the bent
parts is almost impossible. Self-made
measuring tools try to fill this gap within
the existing measuring equipment. An
ideal solution would offer a movable
product that can quickly measure the
shapes of tubes and compare these with
the original CAD drawings.
Prodim developed the TubeCheck
for quality control on tubes. This allows
a tube to be measured at any time, at
any place, and for the measured tube to
be immediately checked on-screen. The
measurement can be compared with the
original CAD drawings and to check if
the new product is within its tolerance.
Angles and radii can be checked quickly
and easily, and element lengths and
total lengths can be viewed.
The measured tube with the desired
data and additional project data can
be stored as a report document in
PDF format. This all takes place within
the Proliner, meaning that there is no
need for external equipment. Operating
the Proliner is easy, so there is no
need for additional knowledge of CAD
programming. Everything can be done
in the fabrication process, and the
system provides an easy way to check if
a tube or pipe is bent within its tolerance
and ready for shipment.
The Proliner can also be used to
measure rooms and buildings, such as
complete engine rooms on-board a ship.
Obstacles in those rooms and the tube/
pipe fixture points are measured and
used as a base for the new pipe and
tube design. Defective tube elements
are easily measured as a base to
construct a new pipe.
These measurements are directly
available as 2D and 3D DXF file. The
measurements are used to design the
tubes in the CAD software so as to
avoid any obstacles within the room.
The connection points are often not in
one line or there are obstacles (in height
or width) that should be avoided. This is
visible in the measurement and must be
taken into account in the design.

Weighing and length measurement
marking for steel pipe
QINGDAO Rising provides special
equipment used for the weighing,
length measurement and marking of
pipe and colour band equipment, drifter
machines, spraying paint of steel pipe
surface during seamless steel pipe,
straight seam steel pipe and oil pipe
production processes.
The equipment for weighing and
length measurement marking for steel
pipe is mainly composed of a weighing
device, length measurement device,
spraying code equipment, marking
equipment, colour band equipment
and an electric automatic control
system. Some users can increase or
decrease the devices to meet their own
requirements, such as before steel pipe
packaging, the need to detect and mark
steel pipe according to API standard
requirements. The main purposes are:
to measure steel pipe bar by bar, to
judge whether it is qualified (whether
the pipes’ length, wall thickness and
weight are matched, and whether the
length scope is qualified); to facilitate
production statistics and determine total
length, weight and number
of various specifications of
pipes; to mark the steel pipes’
grade with different colour
bands; and to mark the pipes’
manufacturer, standard, heat
number and production date on
the pipe surface.
The steel pipe drifter machine
is mainly used to detect a pipe’s
straightness, passing from one end of
the pipe to the other with a standard
drift diameter gauge. The equipment is
mainly composed of frame, feed gauge
device, launch gauge device, conveying
system and receive gauge device.
The steel pipe spraying paint machine
is used for anti-corrosion of pipe surface,
to avoid rust during transportation and
storage. The working process is to
move the steel pipe on the spraying
vertical conveyor, and uniformly pass
the outer wall spraying device carrying
the pipe at a certain speed. When the
spraying device detects the workpiece
and marks the diameter, the automatic
spray gun will open and automatically
spray the workpiece’s surface. The
spray gun automatically shuts off when
the workpiece moves out of the spraying
station.
During the spraying process,
overspray is collected by a recycling
hopper and flowed into a recycling
tank. The recyclable paint is reused
after being filtered. Through the mist
and waste gas processing systems,
the distributing mist and organic waste
gas during the spraying process are
exhausted outdoors by fan.
