Powder coated cylinders are in increasing demand, Worthington Cylinders claims, as the requirements of end-user sectors evolve and customers chase ever-more competitive container solutions.
Powder paint technologies were in the gasworld headlines in June 2012, as their pros and cons compared to traditional ‘wet’ paint cylinder coatings were debated with specialists in the field.
It was understood that an element of dissatisfaction was creeping into the market where the handling and refurbishment of powder coated cylinders was concerned. However, the general vibe toward this technique appeared to be one of optimism.
Worthington Cylinders moved completely to this new painting technology in 2009 also for its large high-pressure cylinders, and claims the feedback has been ‘highly satisfying’. In fact, the company is confident in the longevity of powder paint technologies and recently told gasworld that the popularity of this method will be just as enduring as the coating itself.
Such gas packaging offers relatively unparalleled corrosion resistance and therefore represents a cost-effective solution for a number of end-user industries.
“We are proud to have set a new standard in the industry for a most appealing look of a state-of-the-art steel cylinder which is extremely resistant against corrosion for a long period of time and with much improved impact resistance,” explained Gabriele Zeilerbauer, Director of European Sales at Worthington Cylinders GmbH.
“At the same time, we are supplying a more valuable packaging for our customers’ product, the gas. That is almost like selling wine in a stylish wine bottle, it can make the difference. The customer would rather choose the one with the special appearance and probably pay a higher price for it due to the image you create with it, rather than for an average ‘industry standard’ shape – while the product itself may be very similar.”
“For years our key customers were pushing us hard to offer powder coating as this is seen as the best technology in terms of the aforementioned reasons of appearance, long-term corrosion resistance, higher impact and adhesion resistance”

“Our customers’ requirements have changed a lot in the last 5-10 years,” Zeilerbauer continues. “OEMs in our CNG business have become highly demanding as corrosion resistance is vital for the lifetime of a cylinder in a car – and thanks to them, we have already advanced far in our development that they are impressed by this currently incomparable level of quality. Moreover, this technology is environmentally-friendly due to the recycling of the powder’s overspray and the non-use of solvents. This is a clear trend complying with the growing sensitivity of our customers on this topic and our own care about our employees’ health at the same time.”
“The need even accelerated is the offshore business for Worthington, where cylinders are exposed to very harsh environments and need to withstand such climates without any difficulty.”
Zeilerbauer explains that while a number of customer industries have developed a desire for the most rugged and yet aesthetically pleasing product, the industrial gases industry itself can also benefit.
“Also in the industrial gas business there was no way around powder coating. For years our key customers were pushing us hard to offer powder coating as this is seen as the best technology in terms of the aforementioned reasons of appearance, long-term corrosion resistance, higher impact and adhesion properties.”
“Powder coating has been declared this as the new standard in the technical specifications.”
“We are sure that this high standard will be the new standard for many of our customers as they will get used to it. The difference can be seen from the beginning but is getting more and more obvious after years of service. With a Worthington ‘Longlife PowerCoated’ cylinder the customer is granted a high-end asset with the lowest maintenance costs possible, meaning that he saves money considering the total cost of investment for a cylinder’s many decades life-time as the necessity for repainting is, under normal circumstances, extended by many years.”
