API 5DP covers dimensions and marking requirements for API Master thread gauges. Additional product threads and thread gauges as well as instruments and methods for the inspection of threads for line pipe, round thread casing, buttress casing, and extreme-line casing connections are included. It is applicable when so stipulated in the API standard governing the product. The inspection procedures for measurements of taper, lead, height, and angle of thread are applicable to threads having 111/ 2 or less turns per in. (111/ 2 or less turns per 25,4 mm). All thread dimensions shown without tolerances are related to the basis for connection design and are not subject to measurement to determine acceptance or rejection of product. By agreement between the purchaser and manufacturer, the supplemental requirements for Enhanced Leak Resistance LTC in SR22 shall apply.
Thread inspection applies at the point of manufacture prior to shipment, to inspection at any intermediate point, to inspection subsequent to delivery at destination, and to inspection by inspectors representing the purchaser or the manufacturer. The manufacturer may, at his or her option, use other instruments or methods to control manufacturing operations; but acceptance and rejection of the product shall be governed solely by the results of inspection made in accordance with the requirements of this specification.
API SPEC 5DP defines the technical delivery conditions for steel drill-pipes with upset pipe-body ends and weld-on tool joints for usage in drilling and production operations in petroleum and natural gas industries for 3 product requirements levels (PSL-1, psl-3 and psl-2). PS-1 defines wall thickness, impact strength, and yield strength requirements particular to the material grade. Requirements levels PL-2/ PL-3 have extra obligatory requirements.

EU – In an external upset the increased thickness along the outside diameter of the tubing compensates for the metal removed in threading with a straight bore.
IEU – In an internal-external upset thickness is increased along both the inside and outside walls of the pipe to compensate for the metal removed in threading.)
Grade E drill pipe, described as “mild” steel, shows the most affordable yield strength per system location with a yield strength of less than 80,000 psi. It has the ability to endure a greater portion of stretch or “pressure” prior to fracture than higher strength drill pipe grades. It is likewise more resistant to corrosion and cracking. Grade E is used in medium depth wells from 10,000 to 15,000 feet. Grades X-95, G-105, and S-135 are thought about high strength grades. They exhibit increased yield strength which is needed to service deeper wells.
