De Dietrich Process Systems, Stassbourg, France, is offering a service whereby older or damaged glass-lined steel equipment can be refurbished to an as-new condition using the company’s enamel spraying technology.  All glass-lined reactors, tanks, columns, and accessories such as covers, agitators and baffles, can be reglassed if the steel substrate is in good or repairable condition.

 

The process starts once a vessel has been inspected and approved as suitable for reglassing. Next, the old glass lining is removed by shot-blasting.  After any steel repairs and modifications are complete, De Dietrich proceeds with the glassing process. This involves fusing corrosion-resistant DD3009 enamel on to the prepared steel in its computer-controlled electric furnaces. The end product is a high quality, glass-lined steel vessel or accessory. Reglassing, which is also offered for competitors’ equipment, is said to be ideal for situations where time and cost are a primary issue.  The turnaround time is within weeks compared to months to fabricate a new vessel and there is nearly a 35% cost savings compared to buying a new vessel.  Many companies also find reglassing, which is considered a maintenance budget expenditure, preferable to new capital expenditure. All vessels reglassed by De Dietrich Process Systems come with the same standard warranty as new vessels. www.dedietrich.com
