scope:

COVERAGE

This specification covers Group 1 and Group 3 drill pipe as described below in the designations and wall thicknesses as shown in the standards list, Table 1, and in the dimensional tables (Table 7 and Table 8). The requirements of this specification apply to both Groups unless specifically noted.

Group 1 - Grade E drill pipe.

Group 3 - All high strength grades of drill pipe. (Grades X-95, G-105, and S-135)

In the dimensional tables herein, pipe is designated by outside diameter size. The outside diameter size of external-upset pipe is the outside diameter of the body of the drill pipe, not the upset portion.

RETENTION OF RECORDS

Tests and inspections requiring retention of records in this specification are shown in Table 2. Such records shall be retained by the manufacturer and shall be available to the purchaser on request for a 3-year period after the date of purchase from the manufacturer.

TESTING EQUIPMENT

If test equipment, whose calibration or verification is required under the provisions of the specification, is subjected to unusual or severe conditions such as would make its accuracy questionable, recalibration or reverification shall be performed before further use of the equipment.

SPECIAL PROCESSES

Special Processes are the final operations which are performed during pipe manufacturing that affect attribute compliance required in this document (except chemistry and dimensions). The applicable special processes are heat treatment, nondestructive testing, and, if applicable, cold finishing.

CERTIFICATION

The manufacturer shall, upon request by the purchaser, furnish to the purchaser a certificate of compliance stating that the material has been manufactured, sampled, tested, and inspected in accordance with this specification and has been found to meet the requirements

A Material Test Report, Certificate of Compliance, or similar document printed from or used in electronic form from an electronic data interchange (EDI) transmission shall be regarded as having the same validity as a counterpart printed in the certifier's facility. The content of the ED1 transmitted document must meet the requirements of this specification and conform to any existing EDI agreement between the purchaser and the supplier.

Where additional information is required, including the results of mechanical testing, SR15 shall be specified in the purchaser order.
