All About Glass Lined Equipment

https://www.yongchangfrp.com/product-list-glass-lined-equipment.html

Glass-lined equipment refers to vessels and apparatus that have a lining made of glass on the interior surface. This lining is typically applied to steel equipment through a fusion process, creating a strong bond between the glass and the metal substrate. Here's all you need to know about glass-lined equipment:

Applications of Glass-lined Equipment

Glass-lined equipment finds applications across various industries, including pharmaceuticals, chemicals, food and beverage, cosmetics, and specialty chemicals. They are used for processes such as mixing, blending, reacting, distillation, and storage.

Advantages of Glass-lined Equipment

Corrosion Resistance

Glass lining protects the metal substrate from corrosion, making the equipment suitable for handling corrosive materials.

Cleanability

The smooth, non-porous surface of the glass lining makes it easy to clean and maintain, ensuring high purity in the processes.

Thermal Shock Resistance

Glass-lined equipment can withstand rapid changes in temperature without cracking, allowing for versatile operation.

Product Integrity

Glass lining is inert and does not react with most chemicals, preserving the integrity of the products being processed.

Components of Glass-lined Equipment

Glass-lined equipment includes vessels such as reactors, tanks, columns, and pipes, as well as agitators, baffles, and other internal components. These components are designed to withstand the specific requirements of the intended process.

Manufacturing Process

The glass lining is typically applied to the steel substrate through a thermal fusion process. The steel surface is prepared by blasting or grinding to remove any contaminants, and then the glass is sprayed or poured onto the surface. The equipment is then fired in a furnace at high temperatures to bond the glass to the metal, forming a durable, homogeneous lining.
