Buy & Import 9 5/8in N80 API 8RD LTC Thread Casing Coupling from Dongying Lake Petroleum Technology Co., Ltd - China Wholesale Supply

The 9 5/8in N80 API 8RD LTC thread casing coupling is a precision-engineered component for oil and gas well casing systems. It is sized for 9 5/8 inch N80 casing, featuring a long-thread (LTC) design that provides a secure, pressure-tight connection between casing joints. The coupling is manufactured to API 8RD specifications, ensuring compatibility with standard casing strings used in demanding downhole environments.

Constructed from premium steel, the coupling meets the mechanical properties required for N80 grade applications, with high tensile strength and resistance to corrosion and environmental stress. The LTC thread type is standard for casing connections, offering improved torque resistance and sealing integrity compared to short-thread designs. This type of coupling is a standard component in well construction, where it supports structural stability and prevents fluid migration between formations.

These couplings are used by drilling contractors and oilfield service companies for onshore and offshore well completions. Typical applications include vertical, directional and horizontal wells where casing strings are run to isolate formations and protect the wellbore. Buyers should confirm the thread compound compatibility and torque values for their specific well conditions. The supplier is based in Dongying, a hub for China’s petroleum technology industry, and operates from Huanghe Road.

Frequently Asked Questions About 9 5/8in N80 API 8RD LTC Thread Casing Coupling from Dongying Lake Petroleum Technology Co., Ltd
LTC (Long Thread Casing) provides a longer engagement length than STC (Short Thread Casing), which improves torque resistance and sealing integrity. For 9 5/8in N80 applications, LTC is the standard thread type for coupling connections, ensuring better performance under high-pressure conditions.

Sourcing 9 5/8in N80 API 8RD LTC Thread Casing Coupling from Dongying Lake Petroleum Technology Co., Ltd - China Import Guide

Before ordering, verify the coupling’s compatibility with your casing string by confirming the nominal size, grade, and thread type (API 8RD LTC). Check that the supplier can provide API 5CT compliance documentation, including material test reports and dimensional inspection records. Ensure the coupling’s pressure rating aligns with your well’s maximum expected pressure to avoid downhole failures.

Confirm the Incoterms offered by Dongying Lake Petroleum Technology Co., Ltd, as these will determine responsibility for shipping, insurance, and customs clearance. Typical terms for bulk oilfield equipment include FOB (Free On Board) or CIF (Cost, Insurance, and Freight), with lead times varying based on production schedules. Request the supplier’s packaging standards to ensure protection during transit, as couplings are often shipped in wooden crates or steel bundles.

Quality checks should include visual inspection for surface defects, dimensional verification against API 5CT standards, and review of hydrostatic test results. Request third-party inspection if required by your procurement policy. Ensure the supplier provides the API Monogram and traceability information for each coupling. For critical applications, consider witnessing the hydrostatic test or requesting additional non-destructive testing (NDT) such as magnetic particle inspection (MPI).
