Glass-Lined Steel Pressure Vessels
Glass-lined steel vessels combine the structural strength of carbon steel with the universal chemical resistance of borosilicate glass, providing an optimal solution for pharmaceutical, fine chemical, and specialty chemical applications. Roben Manufacturing supplies and integrates glass-lined reactors, tanks, and process vessels engineered for demanding processes requiring absolute product purity and broad chemical compatibility.
Application Importance
Many pharmaceutical and fine chemical processes involve multiple reagents and reaction conditions that would challenge any single metallic material. Glass lining provides excellent resistance to acids, alkalis, and organic compounds across a wide pH range and temperature span. The non-porous, non-catalytic surface prevents product contamination and facilitates cleaning between batches. Roben Manufacturing works with premier glass lining suppliers to deliver vessels meeting the most demanding process requirements.

Frequently Asked Questions
What are the temperature limitations of glass-lined vessels?
Standard glass linings are rated from -20°F to 450°F (-29°C to 232°C). Special glass formulations extend the lower limit for cryogenic applications. Thermal shock limits apply – temperature changes must be gradual, typically limited to 250°F (120°C) differential.
Can glass-lined vessels be repaired if damaged?
Minor glass damage can often be repaired using tantalum plugs or specialized repair compounds. Repair suitability depends on damage location, extent, and process requirements. We can assess damage and recommend repair or replacement options.
What chemicals attack glass lining?
Glass is not suitable for hydrofluoric acid, hot concentrated phosphoric acid, hot concentrated alkalis above 20% concentration, or fluoride-containing compounds. Chemical compatibility should be verified for all process conditions including cleaning agents.
