Description
KCE® SSiC silicon carbide heat exchange tubes/pipes are made of spray granulated silicon carbide powder by extrusion molding and high-temperature sintering. Pressureless sintered silicon carbide (SSiC) tubes/pipes are the core components of silicon carbide tubular heat exchangers (also known as shell and tube heat exchangers). The outer diameter and wall of the pipe are uniform, the surface is smooth, the roundness is good, and the straightness is good. The outer diameter and end face can be precision machined according to the drawing requirements to meet the usage requirements.

Applications
Suitable for chemical processes such as cooling, condensation, heating, evaporation, film evaporation, and absorption of various chemical substances;
Especially suitable for various highly corrosive chemicals etc. such as bromine, sulfuric acid, hydrofluoric acid, nitric acid, hydrochloric acid and other strong corrosive acids, sodium hydroxide or other strong bases, halogenated compounds, salt solutions, and organic compounds.
Advantages
Due to its excellent characteristics such as corrosion resistance (comprehensive chemical corrosion ability, able to withstand mixed acid corrosion such as hydrofluoric acid), high temperature resistance, high thermal conductivity, high hardness, wear resistance, etc., silicon carbide heat exchangers are particularly suitable for working environments such as high temperature, high pressure, strong acid and alkali corrosion, high-speed airflow erosion, particle wear, etc;
It is an excellent high-performance product that replaces graphite heat exchangers, stainless steel heat exchangers, tantalum metal heat exchangers, Hastelloy alloy heat exchangers, fluoroplastic heat exchangers, and glass lined heat exchangers;
