Product Sheet CONQOR 404 EH Phosphate-Base Corrosion Inhibitor
Prevent corrosion on metal surfaces.
Phosphate-based corrosion inhibitor
At relatively low concentrations, the CONQOR 404 EH inhibitor is particularly effective against oxygen corrosion in aerated muds used in underbalanced drilling operations and low solids, nondispersed water-based fluids.
CONQOR 404 EH phosphate-based corrosion inhibitor is used for water-based drilling fluids, brine water systems and air, mist, and foam fluids. It is well suited for applications where calcium scale deposition is a problem, and it is especially effective in highly aerated fluids such as underbalanced drilling operations.
CONQOR 404 EH inhibitor is an all-purpose, water-soluble, organophosphate compound.
CONQOR 404 EH inhibitor is effective at relatively low concentrations such as 2.5 galUS/100 bbl [0.6 L/m3].
If the corrosion rate is unacceptably high, the concentration should be increased to at least 7 galUS/100 bbl [1.7 L/m3].
For aerated systems, an initial treatment of 12 galUS/100 bbl [2.9 L/m3] is recommended. The product should disperse throughout the circulating mud system and can be added either through the chemical barrel or directly to the mud pits, wherever good agitation occurs.
The corrosion rates should be monitored at all times with corrosion coupons. Treatments should be adjusted according to analysis. A good corrosion-control program includes a thorough makeup-water analysis, chemical treatments for corrosive contaminants, and an adequate bacterial control for systems that contain biodegradable additives.
Bioassay information is available upon request. Handle as an industrial chemical, wear protective equipment, and observe the precautions described in the Safety Datasheet.
CONQOR 404 EH inhibitor is packaged in 55-galUS [208-L] epoxy-lined steel drums and in 5-galUS [19-L] plastic pails. It is not a Department of Transportation-regulated material. Store in a dry, well-ventilated area. Keep container closed. Keep away from heat, sparks, and flames. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping, and stacking.
