At Wuxi Repicea, we specialize in delivering custom-engineered heat exchangers tailored to meet the unique challenges of industrial applications. Our glass-lined tube heat exchangers offer superior performance, particularly when dealing with viscous materials that tend to cause fouling and deposit buildup in traditional heat exchangers.
In this blog, we explore how large diameter glass-lined tubes offer significant advantages over silicon carbide tubes, particularly when dealing with highly viscous or sticky substances. We’ll look at how these exchangers can help optimize your heat transfer processes and improve operational efficiency.

1. The Challenge with Small Diameter Silicon Carbide Tubes
Silicon carbide (SiC) tubes are known for their high thermal conductivity and corrosion resistance. However, when it comes to handling viscous materials or thick fluids, small diameter silicon carbide tubes can cause significant issues. The increased friction in smaller tubes can result in slower flow rates, leading to increased pressure drop, reduced heat transfer efficiency, and the accumulation of material deposits along the tube walls. These issues can drastically reduce the overall performance and longevity of your heat exchangers.
2. The Advantage of Large Diameter Glass-Lined Tubes
One of the key advantages of glass-lined tube heat exchangers is the ability to use larger diameter tubes. Compared to small silicon carbide tubes, larger tubes have smoother surfaces, reducing friction and material buildup. The glass lining is highly resistant to corrosion and has an inherently smooth surface, which prevents materials from sticking to the tube walls.
This design helps to mitigate fouling and reduce maintenance by keeping the heat transfer surfaces clean and efficient. It is particularly useful in applications where fluids are viscous, sticky, or prone to crystallization, such as in the chemical, pharmaceutical, and food processing industries.

3. Key Benefits of Custom Glass-Lined Tube Heat Exchangers
Improved Heat Transfer Efficiency
The larger diameter and smooth surface of glass-lined tubes allow for better flow and more effective heat exchange, even when dealing with viscous fluids. This results in improved heat transfer efficiency, reducing energy consumption and increasing overall process productivity.
Enhanced Durability and Longevity
Glass-lined tubes are resistant to corrosion and erosion, ensuring a long lifespan even in harsh environments. The robust glass lining protects the heat exchanger from the corrosive effects of aggressive chemicals, extending its operational life.
Reduced Fouling and Maintenance Costs
The smooth inner surface of glass-lined tubes minimizes the chances of material fouling or scaling. This significantly reduces the need for frequent cleaning and lowers maintenance costs.
