API Square Kelly Drill Pipe
The API Square Kelly Drill Pipe is a rotary drilling component with a square or hexagonal cross-section, designed to transmit rotational torque while allowing axial movement of the drill string. Manufactured from high-strength alloy steel, this kelly bar is built to API 5DP standards and is compatible with standardized rotary shouldered connections. The design supports sizes ranging from 2 3/8 to 6 5/8 inch outer diameter, making it suitable for vertical drilling operations in oil and gas exploration.
Material grades for this kelly pipe include API E-75, X-95, G-105, S-135, and other high-performance alloys, with upset ends available for weld-on tool joints. Typical industry specifications for square kelly pipes include lengths of R1 (18-22 ft), R2 (27-30 ft), or R3 (38-45 ft), with thread types such as NC26, NC31, NC38, NC40, or NC46. The square or hexagonal profile ensures efficient torque transfer, reducing slippage during drilling.
This component is primarily used as a spare part for drilling rigs, trading alongside heavy-weight drill pipes and drill pipe joints in global energy markets. Buyers include drilling contractors and oilfield service companies sourcing API-standardized tubular goods for onshore and offshore projects. Confirm the exact size, material grade, and connection type with the supplier, as these factors determine compatibility with your drill string.

Sourcing API Square Kelly Drill Pipe from Dongying Lake Petroleum Technology Co., Ltd - China Import Guide
Prior to ordering, confirm the exact outer diameter, material grade, and connection type of the square kelly drill pipe to ensure compatibility with your drill string and rig setup. Request the supplier’s API 5DP compliance certificates and material test reports to validate the mechanical properties and manufacturing standards. Verify whether the kelly pipe is supplied with tool joints or if these need to be sourced separately.
Discuss logistics directly with Dongying Lake Petroleum Technology Co., Ltd to determine lead times, shipping options, and Incoterms. Clarify whether the supplier can arrange delivery to your designated port or rig site, and confirm the packaging method to prevent damage during transit. Square kelly pipes are typically shipped in bundled or crated form, but packaging details may vary based on the order size.
Quality checks should include dimensional verification, material certification, and non-destructive testing (NDT) for critical areas such as tool joints and upset ends. Request a third-party inspection report or mill test certificate to confirm compliance with API standards. Ensure all documentation, including heat treatment records and thread compound specifications, is provided before shipment to avoid delays during customs or rig-side inspections.
