BACKFILL

NACE RP-05-72 (1650 Reversion) States "Conductive backfill should be used to lower the total resistance of the ground bed , to improve current distribution of gases .......

Resistively, particle size , specific weight and analysis are factors to be considered for backfills.....

We can provide reasonable technology and high performance metallurgical coke, calcined petroleum coke, Sacrificial anode standard backfill.

Standard Backfill composition

Electricaled Gypsum :75%
