About Tianjin Dalipu Oil Country Goods Co., Ltd. - Steel Tubes Supplier in China

Tianjin Dalipu Oil Country Goods Co., Ltd. operates from Tianjin, China and currently lists five active products in its catalogue. The company focuses on oil country tubular goods, specifically API 5CT oil casing, tubing and related components, which fall under the HS‑4 heading 7304 for iron or steel tubes and pipes. The product set includes a generic "New and Unused API 5CT Oil Casing and Tubing", an "Oil pup joint", and three entries that specify the HS code 7304.29 and materials such as carbon and alloy seamless steel or low‑alloy steel in grades J55, K55, N80, L80 and P110. All items are described as new and unused, indicating they are intended for primary drilling or completion operations in oil and gas fields.

The catalogue groups the tubing and casing products by API 5CT grade, with the material description noting carbon steel and low‑alloy steel compositions. The HS code 7304.29 is used for the three entries that detail the material and grade, aligning with international customs classification for other tubes, pipes and hollow profiles of iron or steel. No additional certifications are listed for the supplier, so buyers should verify compliance with API specifications and any required quality management standards independently. The product count of five reflects a focused portfolio rather than a broad line of unrelated items.

Product Range and Specialties of Tianjin Dalipu Oil Country Goods Co., Ltd.

The supplier’s catalogue offers API 5CT oil tubing and casing in the standard grades J55, K55, N80, L80 and P110, which are the most commonly specified grades for medium to high‑pressure wells. In the industry, these grades are evaluated by tensile strength, yield strength and wall thickness according to API Spec 5CT, and buyers typically request mill test reports that list dimensions, chemical composition and mechanical properties. Carbon and low‑alloy seamless steel are the usual material families for these grades, and the HS code 7304.29 covers them when shipped as finished tubulars. Typical industry variants include coated or corrosion‑resistant finishes such as epoxy or zinc‑phosphate, though the supplier’s listing does not specify any coating.

Trade and Export Information - Tianjin Dalipu Oil Country Goods Co., Ltd.

Exporters of API 5CT tubulars from China commonly ship to oil‑producing regions in the Middle East, North Africa, Southeast Asia and South America, where drilling activity drives demand for casing and tubing. The HS‑4 heading 7304 is monitored by customs authorities for compliance with anti‑dumping duties and safety regulations, and importers often require pre‑shipment inspection reports such as SGS or Bureau Veritas. Standard Incoterms for these heavy steel products are FOB Tianjin port or CIF destination port, with cargo typically loaded in 20‑foot or 40‑foot containers or in bulk on roll‑on/roll‑off vessels for larger volumes. Buyers usually ask for certificates confirming compliance with API Spec 5CT, ISO 9001 quality management and, for offshore applications, NACE MR0175 corrosion resistance certification.

Sourcing from Tianjin Dalipu Oil Country Goods Co., Ltd. - Buyer Guidance

When sourcing from this supplier, request a complete mill test report (MTR) for each grade, confirming dimensions, mechanical properties and chemical analysis as defined in API 5CT. Ask for the supplier’s API certification or a third‑party conformity declaration, and verify whether the products meet any additional standards required for the target field, such as NACE MR0175 for sour‑service environments. Confirm packaging details - tubulars are normally bundled in wooden frames or steel reels and protected with moisture‑resistant wraps - and ensure the shipping terms, container size and weight limits match your logistics plan before placing an order.
