Extruded resin graphite pipes: this type of graphite pipe is with resin powder and graphite powder mixed together, then graphitized in high temperature. This type of graphite pipes is mainly used in heat exchangers, and can be with bigger length compared to the first type. it can reach a length of 6-7meters. but the diameter is not big.
Resin graphite tube, mainly refers to the phenolic resin extrusion of graphite tube. This graphite tube has the characteristics of graphite, and it has the characteristics of phenolic resin, so it is a perfect combination. It has excellent corrosion resistance and good thermal conductivity.This graphite tubes is mainly used in tube type graphite heat exchanger. In many corrosive materials under the conditions of heat transfer is widely used. The graphite tubes that CFCCARBON LTD produced is with 300 C heat treatment, its thermal conductivity is about 30-40w / (m.k), much higher than other non-metallic anti-corrosive materials, and higher than the stainless steel. Therefore, graphite resin tube has long been quietly step into hydrochloric acid, chlor-alkali industry, and into the chemical industry, pharmaceutical, metallurgy, electroplating, printing and dyeing, paper, environmental protection and other industries.
