This oil country tubular goods listing uses API 5CT and OCTG terms for oilfield drilling enquiries. BTC and EUE appear as thread references, while the table identifies carbon steel pipe. Establish the actual tubular role and connection configuration before treating the entry as a complete downhole supply specification.
Define the tubular role and one connection requirement
Ask which tubular type is offered for the intended service and specify its required grade and supply condition. BTC and EUE are not assigned to separate selectable variants here. Select the required connection rather than assuming both are supplied together or can be substituted without project review.
Request a drawing identifying connection designation, size, end configuration and any associated coupling. Agree the relevant gauging and inspection acceptance for that selection. The drill and hydraulic application wording does not establish a qualified drill-string product, a numerical connection rating or acceptance for every oilfield operation.
Check dimensions against the proposed supply specification
The table lists 219–1066 mm outside diameter, and the variants pair 6–20 mm thickness with 12 m or 6 m length. Confirm one actual combination for the chosen tubular role. These generic ranges are not evidence of an accepted API 5CT dimensional schedule or of connection availability.
Clarify the seamless title against the Saw technique entry with manufacturing records. Define the measurement basis of ±1% and verify end condition, round section, hot-rolled surface and non-oiled supply. Ask for the applicable API 5CT edition, exact scope and material traceability, plus the precise ASTM document if required.
Review the oilfield duty and inspection package
Provide pressure, temperature, fluid composition, cycling and imposed loads for selected material and connection assessment. Obtain project-required rating evidence and test reports. API and ISO 9001 labels require certificate verification; they do not establish sour-service suitability or unconditional approval for the proposed downhole duty.
