Product Overview

A glass lined reactor (enamel reactor) is a core pressure vessel designed for chemical, pharmaceutical, and fine chemical processes, combining the structural strength of carbon steel with the exceptional chemical inertness of glass enamel lining. The glass coating, fused to the inner steel surface at high temperature, creates a smooth, non-porous barrier that resists most acids, alkalis, solvents, and corrosive media—even at elevated temperatures and pressures.

Widely used for mixing, reaction, synthesis, crystallization, and distillation processes, it offers a non-contaminating, easy-to-clean surface ideal for high-purity chemical and pharmaceutical production. Available in standard and custom sizes, with optional heating/cooling jackets, agitation systems, and pressure ratings, it meets strict industry standards for safety and performance.

Key Features & Advantages

✅ Unmatched Corrosion ResistanceThe glass enamel lining is chemically inert to most acids (including hydrochloric, sulfuric, and nitric acids), weak alkalis, and organic solvents. It prevents contamination and eliminates the risk of product discoloration or degradation, even in aggressive reaction environments.

✅ Non-Contaminating & Easy to CleanThe smooth, non-porous glass surface prevents product adhesion and bacterial growth, making it ideal for high-purity API synthesis and food-grade chemical processes. It is easy to clean and sterilize, reducing cross-contamination risks between batches.

✅ High Thermal Stability & Mechanical StrengthThe carbon steel shell provides robust structural support, while the glass lining withstands temperature fluctuations (typically -20℃ to 200℃) and mechanical stress. Optional jacket designs support steam heating, hot water heating, or cooling water circulation for precise temperature control.

✅ Flexible Configuration

• Volume range: 50L–50,000L (custom sizes available)

• Agitation options: Anchor, turbine, or custom impellers, with mechanical seals or packing seals

• Heating/cooling systems: Jacket, half-pipe coil, or internal coil designs

• Pressure ratings: Full vacuum to 1.6MPa (custom pressure ratings available)

✅ Safety & ComplianceBuilt to international standards (ASME, GB150, DIN), with factory pressure testing and lining quality inspection (spark test, thickness measurement). Optional safety features include pressure relief valves, bursting discs, and temperature/pressure monitoring systems.

Working Principle

The glass lined reactor operates as a closed reaction system for controlled chemical processes:

Raw materials are charged into the reactor through designated ports.

The agitation system mixes the materials thoroughly, ensuring uniform heat and mass transfer.

The jacket or coil system circulates heating/cooling media to maintain precise reaction temperatures.

The glass lining prevents corrosive media from reacting with the steel shell, maintaining process purity and equipment integrity.

Vapors from the reaction can be condensed and recovered through overhead connections, supporting continuous or batch operations.
