API 7-1 Square Drilling Hexagonal Kelly Pipe
The API 7-1 Square Drilling Hexagonal Kelly Pipe from Dongying Lake Petroleum Technology Co., Ltd serves as the drive component of the drill stem, available in square or hexagonal configurations. It is manufactured from AISI 4145H modified alloy bars, quenched and tempered full-length to achieve a Brinell hardness of 285-341 BHN. The ends, drive cross-section, IDs, and connections are machined and inspected to API Spec 7-1 and SY/T6509-2000 standards, ensuring precision and reliability.
Ultrasonic inspection is performed on all sections of the kelly pipe to detect internal flaws, and the product is shipped in protective steel-cased scabbards to prevent damage during transit. The kelly pipe’s design allows it to transmit rotational torque from the rotary table to the drill string while accommodating the drilling fluid flow. Buyers must specify the kelly type, nominal size, overall length, and connection details when ordering.

Contractors and oilfield service providers source these components for their durability and compliance with international standards.

Before ordering the API 7-1 Square Drilling Hexagonal Kelly Pipe, confirm the kelly type, nominal size, overall length, and connection specifications to ensure compatibility with your drilling rig. Request API Spec 7-1 compliance certificates and ultrasonic inspection reports to verify the product meets the required standards for material and structural integrity.
