Abstract
Wood-stave and especially wood-lined steel pipe is extensively used to transport corrosive and abrasive substances at temperatures up to 185 F. Wood is especially useful in handling pulp suspensions, pulpmill wastes, mine wastes, dilute mineral acids and dilute caustic soda solutions. Its acceptable pH range is from 2.5 to 11. It is not recommended for use with strong oxidizing agents, concentrated mineral acids or highly alkaline or caustic solutions. It is used successfully to exhaust many kinds of corrosive fumes and vapors.
Short term laboratory and lengthy service experience have shown that even under pressures up to 100-200 psi liquids seldom penetrate halfway through standard thicknesses of staves. This keeps corrosion at the wood-steel interface of wood-lined pipe at a minimum.
Other assets are sustained low friction coefficients and a degree of insulation from temperature. 4 tables, 16 references and bibliography.
