Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›This API coupling is designed for connecting two joints of oil tubing or casing, with a specification range spanning tubing couplings from 33.35mm x 80.96mm to 141.30mm x 158.75mm and casing couplings from 127mm x 158.75mm to 553.4mm x 269.88mm. It adheres to API 5CT and 5B standards and is available in grades J55, K55, N80-1, N80 Q, C90, C95, T95, P110, and Q125. Thread types include NUE, EUE, VAM, STC, LTC, BTC, Special Clearance, XC, VAM TOP, and NEW VAM, ensuring compatibility with a broad selection of pipe configurations.
The couplings are manufactured from carbon steel and feature color-coded paint to indicate different steel grades, simplifying on-site identification. Tubing and casing couplings are typically produced to tight tolerances to ensure leak-proof joints under high-pressure conditions. Standard surface treatments may include anti-corrosion coatings for extended service life in harsh environments.
These couplings are primarily used in the oil and gas industry for well construction, where they join lengths of tubing or casing to form continuous strings. Buyers typically source them in bulk for drilling operations, with packaging options like wooden cabins or pallets to protect against damage during transit. Importers should confirm thread compatibility with their existing pipe inventory before ordering.

Before ordering API couplings from Hunan Prime Steel Pipe Co., Ltd., verify that the thread type and grade match your existing pipe inventory to ensure compatibility. Request a material test report (MTR) to confirm the steel grade and mechanical properties, as these are critical for performance in oilfield applications.
Confirm the supplier’s lead time for bulk orders, as API couplings are often produced to order. Discuss Incoterms such as FOB or CIF to clarify responsibility for shipping and insurance, and agree on payment terms that protect both parties. Port of loading in China should be specified to coordinate logistics.
Inspect the couplings upon arrival for dimensional accuracy, thread integrity, and surface finish. Request a third-party inspection if necessary, and ensure all documentation, including API compliance certificates and packaging lists, is provided. Check that color-coded paint matches the ordered grades to avoid mix-ups during installation.
