Casing coupling /tubing collar in best price
The product is a casing coupling, also known as a tubing collar, offered by Tianjin Jinggong Metal Products Co., Ltd. It is supplied in diameters ranging from 1.9 inches to 20 inches, matching standard oil‑field sizes. Available material grades include J55, K55, N80‑1, N80‑Q and P110, providing options for various pressure and corrosion requirements. Thread configurations cover NU, EU, STC, LTC, BTC and VAM TOP, and the couplings comply with API 5L, API 5CT and ISO 9001:2008 standards, with surface treatment either whole phosphating or internal phosphating combined with external coating.
Typical industry practice limits the maximum working pressure to around 10 000 psi for these grades, although exact ratings depend on the selected material and wall thickness. Unit weight generally falls between 2 kg for the smallest 1.9 in coupling and up to 30 kg for the 20 in size, influencing handling and freight planning. Standard packaging is a wooden crate with one unit per crate, protected by internal padding to prevent surface damage during transport. The couplings are often inspected to API 5L requirements, including hydrostatic testing and dimensional verification.
Oil‑field service firms, drilling contractors and well‑completion engineers commonly purchase these couplings for pipe‑string assembly and pressure‑testing operations. Tianjin Jinggong lists the product without a published MOQ, price or lead‑time, so buyers should request these details directly. Shipping can be arranged on FOB or CIF terms, and payment is usually secured by a letter of credit or advance payment, subject to supplier agreement. Confirm the exact thread designation, material certification and surface‑treatment specification before finalising the order to ensure compatibility with the intended well design.

Sourcing Casing coupling /tubing collar in best price from Tianjin Jinggong Metal Products Co., Ltd. - China Import Guide
Before placing an order, verify the material grade certificate, API compliance documentation and thread type drawing to ensure the coupling matches the well design. Request a dimensional inspection report and confirm the surface‑treatment process, especially if corrosion resistance is critical for the intended environment.
Logistics for this product are typically arranged on FOB or CIF terms. Buyers should confirm the expected lead time, shipping port and any freight forwarder requirements with the supplier. Payment methods such as a letter of credit or advance payment are common, but the exact terms should be agreed in the final contract.

Ensure that the supplier provides a full set of documentation, including material test reports and coating verification, to satisfy import compliance requirements.
