This standard provides comprehensive guidelines for the site selection, layout, and installation of pressure impregnation plants used for the chemical preservation of timber. It details the mechanical requirements for essential plant equipment like treating cylinders, pressure vessels, and pumps, along with critical safety and operational protocols.
Guide for installation of impregnation plants for timber
Quick Reference Values
Typical cylinder working pressure1.05 to 1.40 N/mm2 (10.5 to 14 kgf/cm2)
Typical minimum vacuum560 mm of Mercury
Practical Notes
Ensure treating cylinders are designed, fabricated, and tested as unfired pressure vessels strictly per IS 2825.
Storage tanks and piping handling water-soluble timber preservatives must be appropriately coated with anti-corrosive linings.
Plant layout must include adequate effluent collection sumps and drainage to prevent environmental contamination from preservative spills.
