从China供应商批发进口13-3/8 L80 Btc Collar — FOB条款

The 13-3/8 L80 BTC Collar is a critical downhole component used in oil and gas well casing and tubing strings. Manufactured by Tianjin Dalipu Oil Country Tubular Goods Co., Ltd in China, this collar is designed to connect sections of 13-3/8 inch casing pipe. It is produced to the API 5CT specification, which governs the material grade (L80) and thread type (BTC, or Buttress Thread Casing).

L80 grade steel is a standard material for this application, offering a yield strength of 80,000 psi and good resistance to sulfide stress cracking, which is important in sour well environments. The BTC thread profile provides a reliable, gas-tight seal and is designed for high tensile and compressive loads. Typical dimensional specifications for a 13-3/8 inch collar include an outer diameter of approximately 14.375 inches and a length that varies based on the manufacturer's design.

This component is procured by drilling contractors, oilfield service companies, and operators for well construction and completion operations. Sourcing from a Chinese manufacturer like Tianjin Dalipu offers a cost-competitive option. Buyers should verify the supplier's API monogram license, request material test reports (MTRs), and confirm lead times and shipping terms (e.g., FOB Tianjin) to ensure the product meets project specifications and delivery schedules.

Tianjin Dalipu Oil Country Tubular Goods Co., Ltd is a manufacturer based in Jinghai, Tianjin, China. The company specializes in oil country tubular goods (OCTG), which includes products like casing, tubing, and associated accessories such as collars. Its location in Tianjin places it within a major industrial and port region in China, which can be advantageous for logistics.

The supplier's profile indicates a 'harbor' trust tier. The listing states the product is manufactured to API 5CT standards, but it does not confirm whether the company holds an active API monogram license for this specific product. Buyers must independently verify the supplier's API certification status and request current quality management system documentation before committing to an order.
