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.
Grade: E75, X95, G105, S13
The wear-resistant belt of tool joint: Arnco 100XT, 200XT, 300XT, 400XT;
Internal coating drill pipe: TK34, DPC, TC2000, TC3000
