2.5 Hours Emergency Response Service for Glass Reactors
Will include scheduled inspection. Installed vessels should be inspected every 6-12 months while in operation to establish a baseline service record to determine the wear rate for the glass lining. These inspections will build a database of data that can determine corrosion rates leading to predictive maintenance of the vessel and accessories. An excellent preventative maintenance program.
Spark Test and Glass Integrity Inspection
Spark testing is an important maintenance technique used on glass-lined equipment. It is used to locate defects in the glass lining of vessels and accessories, to perform routine preventive maintenance checks, to verify suspected failure, and to locate areas to be repaired.
Measuring the glass thickness is critical to the life of the vessel. Periodic measurements of the lining should be taken using a magnetic induction or eddy current type instrument with an accuracy of at least ±5%.
As a result of high temperature during the lining process, the glass-lined flanges may warp slightly. Most frequently, the amount of warpage is insufficient to cause a sealing problem. If the gap between mating flanges exceeds 1/16″ at any point around the circumference, the gasket must be shimmed to reduce the possibility of leakage and prolong the service life of the equipment.
Any damaged areas no matter how small, should be immediately repaired. There are many different methods of repair such as tantalum repair plugs, patches or sleeves as well as PTFE repair sleeves that can be used to successfully repair damaged areas of the lining.
The installation of PTFE nozzle liners to all service nozzles will provide additional protection to the glass-lined surface against thermal shock, corrosion and erosion.
Mechanical Seal Repair and Replacement
All mechanical seals must be pressurized to provide a differential above the maximum process pressure in the vessel. Recommended differentials are 15-20 psig above for wet running mechanical seals and 5-10 psig above for dry-running mechanical seals.
Jacket Performance Test and Inspection
Jackets of vessels are subject to fouling due to a build-up of deposits from heating and cooling. As reactor jackets become fouled with iron oxide corrosion, production is negatively affected. Over time, internal fouling of the jackets in glass-lined steel reactors reduces heat transfer efficiencies, increases reaction times and decreases yields by much as 15%.
Complete Vessel Strip-Down and Rebuild
Complete vessel strip-down and rebuild includes replacing/rebuilding wear parts and seals; restoring interior and exterior finishes; completing major vessel and hardware repairs; and updating control and hydraulic systems.
Re-Glass of all Brands / Other Manufacturers
CPI Technology offer re glass of DeDietrich, Pfaudler, Estrella, 3V, Thaletec and Tycon Technologies units and parts. Vessels will have all the glass-lining removed, will be weld repaired, and modified if required, and then be completely relined with highly corrosion resistant glass lining.
