Carbon–9A

GENERAL INFORMATION

Carbon – 9A - carbon wireline (API 9A standard) applicable in wells with very low content of hydrogen sulfide H2S and carbon dioxide CO2.

MAIN DELIVERY CONDITIONS

Wire Carbon–9A it is delivered in the cold-drawn and cleaned conditions, with fixed lengths, in protective lubricant, one length, without welded connections on metal coils

The wire is covered with continuous thin layer of conservation oil, which protects it from corrosion. Upon the demand of the customer it is possible to order it without oiling.

Bundles, coils, spools are packed in water-proof paper, a polymeric film or polypropylene fabric.
