▎ 摘　　要

NOVELTY - Graphite tube comprises pipeline body and resin layer loaded on the surface of the pipeline body, where raw material of resin layer includes 30-65 wt.% phenolic resin, 2-10 wt.% epoxy resin, 8-20 wt.% unsaturated resin, 8-15 wt.% furan resin, 1-5 wt.% graphene and 15-35 wt.% graphite powder. USE - The graphite pipe is useful in shell and tube heat exchanger (claimed). ADVANTAGE - The graphite pipe: has non-oxidizing acid resistance, hydrofluoric acid resistance, weak alkali resistance, aromatic solvent resistance and wear resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphite tube comprising immersing the pipe body in the resin matrix liquid to form resin layer on the surface of the pipe body, where resin matrix liquid is formed by mixing phenolic resin, epoxy resin, unsaturated resin, furan resin, graphene and graphite powder.
