The product offered is a seamless oil casing pipe manufactured to API 5CT specifications. It is produced from carbon‑steel grades J55, K55, N80, L80 and P110, each designed for specific pressure and temperature regimes. Outer diameters are supplied from 4.5 inches up to 20 inches, matching the standard size chart used in well construction. The pipes comply with API 5CT and are classified under HS code 7304.29.
In the oil‑field sector, API 5CT casings typically feature wall‑thickness schedules that range between 0.250 and 2.000 inches, depending on grade and diameter. Standard tensile strengths for these grades lie between 65 ksi and 120 ksi, while yield strengths fall in the 55 ksi to 100 ksi interval, as defined by API testing methods. Typical quality control includes API 5CT visual inspection, hydrostatic pressure testing and dimensional tolerance checks to ±0.125 inches. The material is delivered without external coating, which is common for seamless carbon‑steel casings.
These casings are used by drilling contractors, oil‑field service companies and national oil companies for constructing multiple casing strings in both conventional and unconventional wells. Buyers usually request FOB or CIF terms and may arrange payment by L/C or T/T, as indicated in the supplier’s trade options. While the supplier mentions flexible minimum order quantities, exact MOQ and lead time should be confirmed directly with Tianjin Dalipu Oil Country Tubular Goods Ltd.

Before placing an order, verify the supplier’s API grade certificates and request recent mill test reports to confirm compliance with API 5CT. Checking the supplier’s harbour‑tier verification and requesting a company profile can help assess credibility.
Discuss logistics early: confirm whether the shipment will be FOB from Tianjin Port or CIF to the destination port, and agree on the preferred payment method such as L/C or T/T. Lead‑time estimates should be obtained directly, as the listing does not specify production schedules.
Arrange an independent inspection at the factory or upon arrival to verify dimensions, wall thickness, and mechanical properties. Request the test certificates, packing list and a certificate of origin to satisfy customs and quality‑assurance requirements.
