The tubing is available in carbon steel and alloy steel, with grades J55, N80, and P110 meeting the stringent requirements of the energy sector. Nominal outer diameters range from 2 3/8 inch to 4 1/2 inch, providing compatibility with standard oilfield equipment and pipeline infrastructure.
The material composition ensures high strength and resistance to harsh downhole conditions, with typical wall thicknesses falling between 0.190 inch and 0.660 inch depending on the grade and application. These tubes are produced via hot rolling or cold drawing, with typical length tolerances of ±300 mm for standard mill lengths. The surface is usually bare or coated with a protective varnish to prevent corrosion during storage and transport.
API steel tubing is primarily used in onshore and offshore drilling rigs, where it serves as a conduit for fluids and structural support for well casings. Buyers in the oil and gas industry source these tubes for exploration and production projects, often requiring large volumes to support extended drilling campaigns. The product is typically shipped in bundles with wooden or steel skids, and buyers should confirm packaging specifications, incoterms, and lead times directly with the supplier.

Before ordering API steel tubing from Permanent Steel Manufacturing Co., Ltd., verify the mill test certificates and API 5CT compliance documentation. Confirm the exact grades, dimensions, and wall thicknesses required for your project, as these directly impact performance in downhole conditions. Request third-party inspection reports if additional assurance of quality is needed.
Discuss logistics details such as packaging, bundling, and skid specifications to ensure safe transport and handling. Clarify the incoterms (e.g., FOB, CFR, or CIF) and lead times, as these will affect delivery schedules and cost calculations. Payment terms, such as Letters of Credit or Telegraphic Transfer, should also be agreed upon in advance to avoid delays.
Conduct quality checks upon receipt, including visual inspection for surface defects, dimensional verification, and non-destructive testing if applicable.
