Tube sheet treatment solutions:

Automation in heat exchanger production processes is one of the key sectors developed by RMA Sp. z o.o. Over the past few years, we have designed & developed many new technologies that have contributed to increased efficiency as well as the quality of manufactured products.

The most important processes in Tube Sheet treatment, such as automatic line changeover, vision systems application, tubes trimming and expanding, and also tubes to tube sheets orbital welding – can be easily automated
by industrial robots and our experience.

RMA's solutions

Automated tube-end trimming

Automatic Expanding ToolAutomatic Expanding ToolThe objective of the robot-mounted expanding head is to obtain the smallest possible gap between the tube and tube sheet.

 

The process is repeated pipe by pipe thought following steps:

• Local control of tool distance from the reference surface
• Inserting the expander inside the tube
• Tube forming
• Tool withdrawal

Automatic expanding tool

Automated Tube-end Trimming,

The objective of the trimming  tool is to provide the required distance between the tube-end and the reference surface (tube sheet)In order to streamline the process, an automatic tube-end trimming process has been introduced, which is performed as follows:

• Locating tubes
• Designating the local base area
• Measuring tube stick-out  outside the reference plane
• Centering the tool against the axis of the machined tube
• Tube-end trimming to a defined height
• Verification of the trimming process

Tubes orbital welding and accuracy calibration

Tubes to Tube sheet Automatic Orbital Welding of the tube to tube sheet is the last stage of manufacturing perfect quality tube bundle. The whole process is controlled by very accurate pathfinding system which controls and monitors welding parameters. Thanks to that we have improved quality and ensured high productivity which is the biggest advantage of this technology.

The process is as follows:

• Finding position of the tube

• Measuring local surface of the tube sheet

• TIG or Laser Welding

  • All operations are performed on one platform powered by 6-Axis industrial robot

  • Fully automated & adjustable production station

  • Automatic tools changeover

  • Accurate path finding system which controls and monitors welding parameters
