1. DRILL PIPE ASSET & COMPONENT PRESERVATION GUIDE (BY COMPONENT AREA)
INTERNAL BORE (VOID SPACE)
MAIN THREATS:
Condensation, Pitting, MIC, and atmospheric corrosion.
CAUSE & EFFECT:
Trapped humid air, dew point fluctuations, chloride-containing moisture, and bacterial contamination.
VAPPRO SOLUTION:
Vappro 851 VBCI Fogging Fluid, Vappro VBCI 823 (Add Vappro VBCI OP 529 if water is present).
PROTECTION MECHANISM:
Adsorbs VBCI molecules on internal surfaces for continuous vapor-phase molecular protection and microbial control.
PIPE BODY & ENDS (EXTERNAL SURFACE)
MAIN THREATS:
Atmospheric, Salt Spray, Flash Rusting, and Galvanic Corrosion.
CAUSE & EFFECT:
Oxygen, humidity, marine chloride deposition, transport exposure, and mixed-metallurgy at tool joints.
VAPPRO SOLUTION:
Vappro VBCI 868 (Augmented with Vappro VBCI 887 Surface Passivator at tool joints).
PROTECTION MECHANISM:
Provides a hydrophobic barrier and surface passivation to block electrochemical cell formation.
THREADED CONNECTIONS (TOOL JOINTS & PROTECTORS)
MAIN THREATS:
Thread, Crevice, and localized Under-Protector Corrosion.
CAUSE & EFFECT:
Moisture ingress into thread roots and differential oxygen concentration (aeration cells) beneath thread protectors.
VAPPRO SOLUTION:
Vappro VBCI 869 (Paired with Vappro VBCI 823 inside protector caps).
PROTECTION MECHANISM:
Excludes moisture and oxygen through contact inhibition combined with localized vapor-phase protection.
