Casing & Tubing Coupling
Casing and tubing couplings from Tianjin Dalipu Oil Country Tubular Goods Co are manufactured to API standards for oil and gas applications, ensuring structural integrity under high-pressure conditions. The couplings connect casing and tubing strings, providing a leak-proof seal critical for drilling, completion and production operations in exploration and production fields. Each unit is designed to maintain mechanical strength in corrosive environments typical of downhole use.
The products are constructed from high-strength steel grades selected for API compliance, with material properties tuned for durability in extreme temperatures and pressures. Standard industry practice for such couplings includes heat treatment to enhance mechanical properties, with typical yield strengths ranging from 55 ksi to 110 ksi depending on the grade. Surface treatments such as phosphating or anti-corrosion coatings are applied to extend service life in harsh downhole conditions.
These couplings are used in onshore and offshore wells where reliability under cyclic loading is essential. Buyers typically source them in bulk for large-scale projects, with packaging designed to prevent damage during transit. Common trade terms for such shipments include FOB or CIF, with payment via L/C or T/T. The supplier’s location in Tianjin provides logistical advantages for export to global markets.

Sourcing Casing & Tubing Coupling from Tianjin Dalipu Oil Country Tubular Goods Co - China Import Guide
Before ordering, verify the exact API standard compliance and material grade for the couplings to ensure they match your project’s specifications. Confirm the thread type compatibility with your casing or tubing strings, as mismatches can lead to costly downtime. Request the supplier’s mill test reports and third-party certifications to validate the product’s integrity.
Discuss logistics details such as lead times, which can vary depending on the order size and the supplier’s production schedule. Clarify Incoterms, with FOB or CIF being common for bulk shipments of this nature. Payment terms such as L/C or T/T should be agreed upon in advance to avoid delays in processing.
Inspect the couplings upon arrival for dimensional accuracy, thread integrity and surface treatment quality. Conduct a visual and dimensional check against the API 5CT standard to ensure compliance. Request documentation such as packing lists, test certificates and material traceability to confirm the shipment meets your requirements.
