Pipe and Tube Marking Processes
Several marking methods is suitable for pipe and tube marking. In this section, we discuss three standard pipe marking processes you can employ in your production process.
Scribing Marking Method
The scribing marking system involves the use of a scribe to mark the pipe or tube. The readability of the marking depends on the scribing machine you use and the material’s hardness and thickness.
Why is Scribing Marking Machines Suitable for Pipe and Tube Marking?
Scribing marking machine is an ideal machine for pipe and tubes because of the following reasons:
· Highly Readable Markings
Scribing machines on their use on a pipe or tube will produce markings of high readability. However, the readability depends on the stylus material you are using. With materials such as diamond and carbide, you can get a very highly readable marking.
· It Does Not Lead to Thermal and Chemical Stress
Scribing machines does not lead to thermal and chemical stress. Therefore, you can use them with materials sensitive to heat and chemicals.
Limitations of Scribing Marking System
The scribing marking system also has its limitation. For example, it is only suitable for low-volume marking. Consequently, it is not production efficient when used with large tubes and pipes.
Laser Engraving Method
Laser engraving is another marking process effective in pipe and tube marking. Laser engraving on pipes involves applying laser beams on pipes and tubes to engrave deep and permanent marks on the material.
The laser beam marks the pipe or tube surface by removing layers on the designated area of the tube with the laser beam. In the process of pipe engraving, the contact between the laser and pipe generates a massive amount of energy, producing the heat necessary for vaporization.
Why is Laser Engraving Better for Pipe and Tube Marking?
Laser engraving is an effective marking process on pipes and tubes. Below are reasons why it is suitable:
· Laser Engraving is Very Precise
Laser engraving is a precise method. Consequently, many people prefer it for working with pipes and tubes.
· Highly Readable Markings
Laser engraving produces highly readable markings on any material used in making the pipes and tubes.
· Material Compatibility
Laser engraving is compatible with a wide range of materials. However, you should avoid pipes and tubes made from chlorine-containing compounds.
· It is Production Efficient
Due to software use, laser engraving is efficient and effective in working with multiple pipes and tubes. However, you must consider the laser marking machines you want to use as they play a huge role in the efficiency of the process.
Limitations of Laser Engraving
The main limitation of using laser engraving is that the laser engraving machines are costly. Therefore, your budget will decide if you can work with the method or not.
Inkjet Printing Method
The injection printing process is popularly known for its simplicity, thereby making it an appropriate marking process. It uses both color pigment and inkjet printers to mark tubes and pipes for easy identification.
In the inkjet printing process, the ink travel at a high speed. It contacts the pipe surface through the nozzles and marks on the pipes and tubes.
Why Inkjet Printing is Suitable for Pipe and Tube Marking
Injection printing is an effective marking process on pipes and tubes. It produces highly readable markings, and it is compatible with a wide range of materials.
Limitation of using Inkjet Printing for Pipe and Tube Marking
Injection printing has huge material support. However, the ink is only compatible with a set of materials. It can be unsuitable for marking some materials such as Teflon. Also, there is a need to obtain different ink cartridges for different materials. Consequently, there is an increase in cost.
