Glass lined heat exchanger

The glass lined heat exchanger is a core equipment in the fields of chemical,pharmaceutical,food and other highly corrosive media treatment.It improves the corrosion resistance of traditional metal heat exchangers to a new height by sintering enamel glass coatings on the surface of metal substrates.This device,with its unique material properties and structural design,has become the primary choice for heat exchange under corrosive conditions such as sulfuric acid,hydrochloric acid,and organic solvents.
The glass lined heat exchanger is composed of a carbon steel or stainless steel substrate and three layers of enamel glass coating:the bottom layer is a bonding layer,the middle layer is a transition layer,and the surface layer is a high silicon acid resistant glaze.This multi-layer structure achieves molecular level bonding through high-temperature firing at 900℃,allowing the equipment to remain intact under a temperature difference of 120℃thermal impact,and the mechanical impact strength is three times higher than that of ordinary enamel.
With the tightening of environmental regulations and the increasing demand for manufacturing,glass lined heat exchangers are developing towards intelligence and integration.The IoT monitoring system developed by a certain enterprise can monitor 12 parameters such as heat transfer efficiency and corrosion rate in real time.Predictive maintenance improves the overall efficiency of the equipment to 92%.Under the"dual carbon"goal,the use of glass lined heat exchangers in waste heat recovery systems can reduce energy consumption in chemical enterprises by 15-20%,becoming an important support for green manufacturing.For production enterprises involving highly corrosive media,choosing suppliers with core coating technology and engineering service capabilities is not only a way to obtain equipment,but also a strategic choice to build sustainable competitiveness.
