In the realm of compressed natural gas (CNG) transportation, maintaining the highest quality standards for cylinders is crucial to ensure safety and reliability. Ensuring the highest quality of CNG cylinders is vital for safe and reliable transportation. These cylinders store CNG under high pressure, and any imperfections can lead to catastrophic failures. By adhering to strict quality standards, manufacturers guarantee cylinders meet strength, durability, and reliability requirements, reducing accident risks and safeguarding public well-being.

The Challenge

The company specializing in CNG manufacturing encountered several obstacles. Firstly, they faced difficulty in testing CNG cylinders due to their complex shapes, making direct testing a challenging and mounting a laborious process. Ensuring accuracy and consistency proved challenging due to manual labor, resulting in time-consuming measurements. Meeting safety standards necessitated 100% testing compliance, which was difficult to achieve manually. Additionally, the manual testing process was inefficient and couldn’t keep pace with the production rate, particularly given the production of numerous CNG cylinders and their heavy weight.

The Solution

We recommended the implementation of an Inline Hardness Tester to determine the suitability of the cylinders for further use. By integrating the Brinell hardness tester into the production line, manufacturers could quickly assess the hardness of materials, identify any inconsistencies or defects, and make necessary adjustments or corrections as and when required. This innovative system would enable 360-degree testing as the cylinder rotates fully, with a particular emphasis on the crucial parameter of 360-degree indent testing. The automated nature of this system not only streamlines the testing process but also minimizes human error, ensuring greater precision and efficiency in the assessment of cylinder hardness.




  • Enhanced Precision: It provides highly accurate hardness measurements, ensuring material consistency and quality.
  • Improved Efficiency: Testing is expedited compared to traditional methods, reducing production time and costs, and minimizing downtime to optimize overall operational efficiency.
  • Real-time Feedback: Continuous monitoring offers immediate insights into material quality, facilitating quick adjustments if needed.
  • Quality Assurance: The tester reduces the risk of defects in the final product, enhancing overall product quality.
