TKPP (Tetrapotassium Pyrophosphate) is a highly soluble, more environmentally friendly, low sodium alternative to SAPP. It is used as a replacement to SAPP due to its low sodium content where LWD is the preferred method of disposal.
TKPP’s main application is for the dispersion of mud rings when water drilling and as a rapid thinner prior to cementing casing.
In water well applications normally add 1 viscosity cup full of TKPP directly down the drill pipe on each connection. In areas with highly reactive clays, increased treatments may be required. When using to thin the mud prior to cementing, mix as required into the circulating mud system.
