Choice best SIC tube which is composed of reactive sintering and superfine SIC particle, It almost show inert to all known chemicals within 200degree,Our SIC tubes are highly resistant to corrosion and have been test with hydrofluoric acid, bromine, nitric acid, mixtures acid and chlorinated organic products

Chemical medium	temperature(℃)	corrosion rate(mg/cm2 YR)
98% H2SO4	100	1.8
85% H3PO4	100	less than 0.2
53% HF	25	less than 0.2
50% NaOH	100	less than2.5
45% KOH	100	less than 0.2
70% HNO3	100	less than 0.2
37% HCl	86	less than0.2
10% HF 57% HNO3	25	less than 0.2

Excellent Mechanical Properties: Each SIC tube is tested at 18Mpa to guarantee It's safety and mechanical reliability

High Resistance to erosion: Hardness is very high,50% higher than tungsten carbide, SIC tubes is very resistant to erosion ,It allows a higher fluid velocity to improves the heat exchange efficiency

High cleanliness and resistance to permeation :Sic tubes which our company used is pure ,It didn't contains any other filler, It is totally resistant to all fluids and gases even at high temperature and pressure, It avoids contamination in high purity applications

High Thermal Conductivity: Thermal conductivity of SIC is similar to Graphite and much higher than other corrosion resistance materials(PTFE, glass, compound special alloys, noble metals)
