Casing Coupling
Elite Pipe Co., Ltd. manufactures casing couplings for oil and gas wells, designed as threaded connectors to join casing strings during drilling and completion. The couplings are produced from carbon and alloy steel grades including J55, K55, L80, N80-1, N80-Q, C90, T95, C110, P110, and Q125, covering casing sizes from 4-1/2 to 20 inches.
Each coupling is manufactured to API-5CT and API-5B standards, with thread types available in STC (Short Thread Coupling), LTC (Long Thread Coupling), and BTC (Buttress Thread Coupling). The couplings undergo heat treatment to meet mechanical property requirements, with typical yield strengths ranging from 55,000 psi for J55 to 125,000 psi for Q125. Surface treatments such as phosphate coating are standard to enhance corrosion resistance.
These couplings are critical for maintaining the structural integrity of well casings, ensuring pressure containment and alignment during cementing. Importers in the petroleum drilling industry rely on them for onshore and offshore applications. Buyers should specify steel grade, thread type, and size to match their casing strings and well conditions.

Sourcing Casing Coupling from Elite Pipe Co., Ltd. - China Import Guide
Prior to ordering, verify the coupling’s steel grade, thread type, and size compatibility with your casing string. Request API-5CT and API-5B certification documents to confirm compliance with industry standards for your project’s requirements.
Clarify logistics details including Incoterms (e.g., FOB Qingdao or CIF destination port), packaging specifications, and estimated lead times for production and shipping. Casing couplings are typically packaged in wooden crates or bundles to prevent damage during transit.
Arrange for pre-shipment inspection to validate thread integrity, dimensional accuracy, and surface treatment quality. Insist on mill test reports (MTRs) and hydrostatic test certificates to ensure mechanical properties and pressure integrity. All documentation, including certificates of conformity and packing lists, should accompany the shipment for customs clearance.
