Measuring and marking

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. 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.

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.

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

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

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

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

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.

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
