API 5DP Specification and API 5DP Drill Pipe
API 5DP Drill Pipe and API 5DP Specification
Drill Pipe manufactured strictly according to API 5DP standard
Yield strength: Min 517 Mpa
Tensile strength: Min 724 Mpa
Pipe body material: High quality alloy seamless pipe of E75
Thread treatment: Phosphorization or copper plating
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.
Drill Pipe in API 5DP, Diameters from 2 3/8'' to 6 5/8'', Grade DZ50, E75, R780, X95, G105, S135
