On any gas cylinder you are using, you will find many codes made up of alphanumeric characters. Inscribing such codes on a gas cylinder is important regulation and identification –credence to its importance. However, inscribing such codes on gas cylinders is possible via many marking processes, and each process has its marking machines.

To simplify the process, this article talks about gas cylinder marking machines. It will introduce why gas cylinder marking is important and the different rules associated. It will then expatiate on the different marking processes and the ideal gas cylinder marking machines you can use. At the end of the article, you will have a clear idea of how to mark your gas cylinder.

Why Should You Mark Your Gas Cylinders?

Original equipment manufacturers must ensure that the gas cylinder they make must adhere to the safety and stability guidelines determined by the Compressed Gas Association (CGA) and the Department of Transportation (DOT).

Adhering to such guidelines requires gas cylinder manufacturers, fillers, and operators to keep to a standard. To adhere to this guideline, there must be certain markings on the gas cylinder from which information can be drawn to accept, reject, and condemn compressed gas cylinders for continued use. The guideline requires that the gas cylinder contains the following:

  • DOT 3AL 3AA Specification Numbers
  • MFG Date & Location Codes
  • Cylinder TARE Weight
  • Neck Ring Identification & Serial Numbers
  • Service or Working Pressure Indicators

Markings on a Gas Cylinder

Cylinders must have markings designating the following:

  • The top mark indicates pertinent regulations for that cylinder.
  • The second mark is the serial number.
  • The symbol of the manufacturer could be under the serial number.
  • The test dates

Gas Cylinder Marking Processes You Can Use

gas cylinder marking processes you can useThere are many gas cylinder marking processes you can use. However, choosing one depends on how experienced you are with the process and the gas cylinder marking machine associated with it.

The two marking processes ideal for marking gas cylinders are the dot peen and roll marking systems. However, based on efficiency, ease of use, and other operational factors, each one is applicable in different scenarios. Below are the two marking processes you can use for marking gas cylinders.

Dot Peening Marking Process

dot peening marking process

Dot peen is the more popular gas cylinder marking procedure in the modern world. It involves using a pin or stylus controlled pneumatically or electrically to inscribe the necessary codes on the gas cylinder.

The marking inscribed on the gas cylinder is permanent and highly readable. This is a reason for the popularity of dot peen marking machines with gas cylinders.

Why Dot Peening Method is Suitable for Marking Gas Cylinders

The next question is why the dot peen marking process should be on your list in marking a gas cylinder. Below are a few reasons why you should choose the method.

· Thermal and Chemical Stress

With dot peening marking, the gas cylinder is not exposed to thermal and chemical stress. The method does not use or generate any heat, and it does not work with chemicals. Therefore, the surface finishing of the gas cylinder will not change.

· Software Inclusion

This depends on the dot peen gas cylinder marking machine you choose. However, the recommended machines have software that can store code. With the software inclusion, multiple marking procedure is possible which improves effectiveness and efficiency.

· Ease of Operation

The dot peering machine majorly available for marking gas cylinders is easy to manipulate to mark any part of the gas cylinder. The recommended machines are handheld and easy to operate.

· Highly Readable Markings

The marking inscribed by dot peening has very high readability. Consequently, the method is suitable for making gas cylinders.

Dot peening marking boasts of huge advantages when used for marking gas cylinders. However, a disadvantage you have to worry about is that it subjects the gas cylinder to mechanical stress. Also, when used, there is an issue with noise pollution.

Nevertheless, the dot peen marking system is an effective and efficient method for marking gas cylinders.

Roll Marking Process

roll marking process

The last of the marking processes suitable for marking gas cylinders is the roll marking. Roll marking involves using a roll die mounted on a lathe or press to mark the gas cylinder.

The die is on a lathe can be rotated on its axle, and its face can then mark the cylinder surface.

The marking to be inscribed on the gas cylinder is rolled on the die. Roll marking is ideal for marking gas cylinders because it is suitable for marking delicate surfaces. It is a popular gas cylinder marking method for people that mark large numbers of gas cylinders.

Why is Roll Marking Machines Are Suitable for Marking Gas Cylinders?

Why then should you use roll marking machines for gas cylinders? Below are a few reasons you are at an advantage when using the method.

· Thermal and Chemical Stress

Like dot peen marking, roll marking does not subject the gas cylinder to thermal and chemical stress. It does not exude or use any form of heat, and it does not work with or exude chemicals that can alter the gas cylinder surface finishing.

· Cylindrical Marking

The setup of the roll marking machine ensures that you can easily mark gas cylinders irrespective of the cylindrical structure. Even though the setup is not handheld, it removes the limitation of handling, by marking irrespective of such cylindrical nature.

· Size of Cylinder

Roll marking machines are suitable for marking any gas cylinder irrespective of its size.

· Highly Readable Markings

Markings made using roll marking machines are highly readable. Also, due to the efficiency associated with the process, it is the most compatible method for industrial gas cylinder marking.

Original Equipment Manufacturers prefer roll markers due to their ability to produce deep, clean, perfectly aligned aesthetic marks. However, for multiple markings, you need to alter the fixture arrangement and change the tool.

How to Choose the Right Gas Cylinder Marking Machine and Process?

A successful marking process comes with choosing the right method and the right machines. Therefore, it is important to understand the features of the different machines and the peculiarity of the marking methods. The following factors play huge roles in selecting the right gas cylinder marking machine and process.

· What is Your Budget?

Before choosing any method or machine, the most important factor that you must consider is your budget. You must choose a machine or method that will produce an efficient and effective marking while balancing cost.

· What is the Gas Cylinder Size

Some marking machines explained above are not that suitable for marking large gas cylinders. For example, marking a large gas cylinder using dot peening will be less efficient than marking with a roll marker.

· Machine Portability

Handheld machines are easier to operate, manipulate, and maneuver in marking a gas cylinder than roll markers. Therefore, when dealing with a large gas cylinder, you can use a portable dot peen marker. However, for medium and small cylinders, roll marking would be more efficient.

Get the Best in Terms of Gas Cylinder Marking

Marking a gas cylinder is an important identification and regulation step. Therefore, many OEM ensures that the best marking method and machines are utilized in such a process.

Among the marking methods used, dot peening and roll marking are the most common method. This article introduces the two methods, what makes them spectacular, and how to choose the right method and machines.

How do you mark a gas cylinder?

There are many ways to mark a gas cylinder. However, considering the readability and ease of operation associated with making them, there are two important methods. The methods are dot pin engraving and roll marking. Dot pin engraving involves using a pin marking machine to engrave part of the gas cylinder. Roll marking is the mounting of a die on a lathe which is then used to mark the gas cylinder.

What is the most accurate way of identifying cylinders?

Every gas cylinder has a line of code on the upper part of the cylinder. The code includes the following: DOT 3AL 3AA Specification Numbers, MFG Date & Location Codes, Cylinder TARE Weight, Neck Ring Identification and Serial Numbers, and Service or Working Pressure Indicators. These codes identify the gas cylinder.

How should an empty cylinder be marked?

An empty cylinder should be marked with either a dot pin marking machine or a roll marker. Choosing a suitable method of the two depends on the type of cylinder and the production efficiency envisioned.
