The Casing Pipe N80 Oil Casing Pipe is an API 5CT certified tubular product made from carbon steel / low alloy steel to N80 grade. It is offered in outside diameters ranging from 1.05" to 4-1/2" and is intended for oil and gas well drilling and completion where high‑pressure downhole conditions are expected. The pipe meets the controlled yield strength and chemistry requirements defined for N80 grade, providing reliable well integrity. It is manufactured for export and is listed by the supplier for global OCTG procurement.
Carbon steel N80 grade typically exhibits a yield strength around 70,000 psi and a tensile strength near 100,000 psi, values that are standard for this classification. Wall thickness for these sizes usually follows the standard range of 0.065" to 0.375" depending on the selected diameter, with dimensional tolerances defined by API 5CT. The material’s corrosion resistance is enhanced by standard protective coatings, making it suitable for the mildly corrosive environments encountered in many wells. These technical attributes align with industry expectations for N80 casing used in demanding drilling projects.
Typical buyers include drilling contractors, national and international energy companies, and exploration firms that require robust tubular goods for well construction. The supplier states that flexible minimum order quantities and shipping options such as FOB and CIF can be arranged, but the exact terms should be confirmed directly. Importers are advised to request the API test report, mill test certificates and dimensional inspection reports before finalising a purchase. Payment and incoterm details are negotiated on a case‑by‑case basis with the supplier.

Request dimensional inspection records for the specific diameters and wall thicknesses you require, and ensure that the coating type is documented for the intended downhole environment.
Logistics for shipments from Tianjin typically involve FOB terms from the Tianjin port, with CIF options also available. Lead‑time estimates and payment conditions such as L/C or T/T should be agreed with the supplier in advance, as they are not disclosed in the listing. Confirm the incoterm and any freight forwarder requirements before finalising the contract.
