OTCG Tubing

The OTCG Tubing offered by Hunan Great Steel Pipe Co., Ltd is manufactured from carbon steel and low‑alloy steel and conforms to API 5CT grades J55, K55, N80, C75, L80, C90, T95 and Q125. It is supplied with an outer diameter ranging from 40.26 mm to 114.3 mm and a wall thickness between 3.18 mm and 16 mm, covering the dimensions required for most well‑bore applications. End preparation options include beveled cuts, square cuts and both NUE and EUE connections, allowing compatibility with a variety of wellhead equipment. The product is marketed for oil and gas well production operations worldwide.

Typical API 5CT tubing is delivered in the standard length categories R1, R2 and R3, which correspond to approximately 8‑10 m, 10‑12 m and 12‑14 m respectively, and it observes the usual outer‑diameter tolerance of ±0.25 mm. The material grades provide tensile strengths that meet the pressure‑rating expectations of offshore and on‑shore drilling projects. These tubes are a core component in drilling strings, casing‑running tools and production lines, and they are widely traded in the international OCTG market. Buyers benefit from a product that matches the mechanical and chemical requirements specified by API for safe and efficient well completion.
