This API 5DP drill pipe in S135 grade is a seamless steel tubular designed for oilfield drilling, available in outer diameters of 2 7/8", 3 1/2", 4", 4 1/2", 5", and 5 1/2". The S135 designation denotes a minimum yield strength of 135,000 psi, making it suitable for high-stress deep drilling operations where resistance to torque and tension is critical. End finishes include external upset (EU) and internal-external upset (IEU) configurations, with optional hard banding using Arnco100XT or Arnco300XT materials to reduce wear on the tool joint.
The pipe is manufactured to API 5D standards, ensuring compatibility with rotary drilling rigs and adherence to industry tolerances for wall thickness, length, and straightness. S135 grade is a high-strength alloy steel, typically alloyed with chromium, molybdenum, and manganese to achieve the required mechanical properties. Hard banding, when applied, is fusion-welded to the tool joint to extend service life in abrasive formations. Standard lengths for API 5DP drill pipe are typically 9.5 to 10.5 metres, though custom lengths can be negotiated.
These drill pipes are used in onshore and offshore oil and gas exploration, where they transmit drilling fluid and rotational power to the drill bit while withstanding extreme downhole conditions. Buyers in the energy sector prioritise suppliers with consistent dimensional accuracy and traceable heat treatment records. For bulk orders, confirm packaging options, as standard bundles use steel straps and wood or plastic end protectors to prevent damage during transit.

Before ordering, verify the drill pipe’s compliance with API 5DP by requesting the mill test certificate and heat treatment records. Check that the grade (S135) and outer diameter match your rig’s specifications, as mismatches can cause connection failures or reduced performance. Confirm whether hard banding is required for your formation type, as this affects both cost and longevity.
Logistics details to confirm include the supplier’s ability to meet your lead time, as API 5DP drill pipe often requires 4-8 weeks for production. Clarify Incoterms (e.g., FOB Qingdao or CIF to your port) and payment terms, as these can vary by order size. For bulk shipments, discuss containerisation or break-bulk options to optimise freight costs.
Quality checks should include dimensional inspection (OD, ID, length) and non-destructive testing (NDT) for cracks or defects. Request a pre-shipment inspection by a third party to ensure compliance with API standards. Documentation to secure includes the MTC, packing list, and a certificate of origin for customs clearance.
