These are seamless high-strength alloy steel drill pipes manufactured to API 5D specification for petroleum and oil well drilling. The pipes are available in outer diameters from 2-7/8" to 5-1/2", with steel grades E75, X95, G105, and S135, each selected to handle distinct torque and yield strength demands in downhole conditions. End finishes include EU (external upset) and IEU (internal and external upset) configurations, ensuring compatibility with standard drilling rigs and tool joints.
The material composition adheres to oilfield-grade alloy standards, with optional hard banding treatments such as Arnco100, Arnco300, or tungsten carbide to extend service life in abrasive environments. Surface treatments like black painting, varnish, or epoxy coating are applied to resist corrosion during storage and transport, while bevelled or plain ends are offered based on buyer requirements. Typical industry specifications for drill pipes include a minimum yield strength of 517 MPa for E75 and up to 965 MPa for S135, with wall thicknesses standard for each OD grade.
These pipes serve as critical consumables for drilling contractors in the oil and gas exploration sector, where reliability under high-pressure and high-temperature conditions is non-negotiable. Buyers typically source these in bulk for deepwell or horizontal drilling projects, with packaging options such as bundle wrapping and plastic end caps to prevent damage during shipping. Confirm MOQ, lead time, and hard banding availability directly with Tianjin Dalipu, as these are not specified in the listing.

Before placing an order, verify the exact steel grade, outer diameter, and wall thickness required for your drilling conditions. Confirm whether hard banding or specific surface treatments are necessary, as these impact performance and cost. Request third-party inspection of the pipes’ dimensions and material composition to ensure compliance with API 5D.
Discuss logistics details such as lead time, which can vary based on customisation and order volume. Clarify Incoterms (e.g., FOB Tianjin) and payment terms, as these are not specified in the listing. For bulk shipments, confirm whether the supplier can provide containerised or break-bulk loading, and check port restrictions for oversized pipes.
Conduct quality checks upon receipt, focusing on outer diameter, wall thickness, and end finish integrity. Inspect for surface defects or inconsistent coatings, as these can indicate handling damage or substandard treatment. Request a pre-shipment inspection report from a recognised agency like SGS or Bureau Veritas to validate the pipes’ condition before dispatch.
