Hebei Borun Steel Trade Co., Ltd offers casing tubing couplings that comply with API SPEC 5CT and API SPEC 5B. The product covers grades H40, J55, K55, N80‑1, N80, QL80, C95, T95 and P110, with outside diameters ranging from 127 mm to 365.12 mm (4½" - 13 3/8"). Threading options include Short Round Thread (STC), Long Round Thread (LC) and Buttress Thread (BC). Lengths are supplied in R2 (7.62 - 10.36 m) and R3 (10.36 - 14.63 m) ranges.
These couplings are designed for internally threaded joining of two lengths of casing pipe, providing a reliable seal for pipe runs from the surface to the well wall. The typical material is carbon steel, offering standard tensile strengths that correspond to each grade; for example, grade J55 normally delivers around 55 ksi yield strength. Standard dimensions such as bolt circle diameter and coupling width follow industry norms for the specified OD range.
Buyers usually order in bundles that match project‑specific pipe lengths and may request either FOB or CIF shipping from the nearest Chinese port. Before finalising, confirm the preferred Incoterm, payment schedule and any required documentation, such as a material test report and third‑party inspection certificate, to ensure the couplings meet project specifications.

Start by confirming that the couplings carry the required API certification and request a recent material test report for the specific grade you intend to use. Ask the supplier to provide ultrasonic and hydrostatic test certificates, as well as a certificate of origin, to validate compliance with project specifications.
Discuss shipping preferences early: decide whether you need FOB or CIF terms, identify the nearest Chinese port for loading, and clarify the expected lead time for the chosen length and diameter range. Agree on a payment method such as T/T against documents or a confirmed letter of credit, and verify any required export documentation from China.
Plan a quality verification process upon arrival by arranging a third‑party inspection at the destination port. The inspection should cover dimensional accuracy, thread integrity, wall thickness and surface condition. Ensure the supplier includes the inspection report, packing list and any relevant test certificates in the final documentation package.
