API 5DP Drill Pipe Specifications: Size, Weight, Wall Thickness & Dimensions

Compare Shangshanpetro drill pipe body dimensions and common tool-joint configurations from 2-3/8 in through 6-5/8 in. Use the tables below to check nominal weight, wall thickness, calculated body ID, steel grade, upset, connection and grade-specific tool-joint data before requesting the final approved manufacturing datasheet.

API 5DP drill pipe is not defined by outside diameter alone. A usable technical description combines nominal pipe size, nominal weight, wall thickness, grade, upset, connection and the required tool-joint geometry. The database below separates pipe-body dimensions from grade-specific tool-joint dimensions so replacement and new-build configurations can be checked more accurately.

API 5DP Drill Pipe Size & Weight Chart

This is the primary body-dimension reference. Calculated body ID = pipe OD − 2 × nominal wall thickness. Final tolerances and manufacturing dimensions follow the approved datasheet and purchase order.

* Final S135 tool-joint dimensions for the 5 in × 25.6 lb/ft NC50 configuration must be confirmed in the approved manufacturing datasheet.

Quick Tool-Joint Connection Reference

Connection designation alone does not define the complete tool joint. Use the detailed size sections below for tool-joint OD, pin ID, bevel diameter, tong-space length, upset-neck OD and torsion ratio.

API 5DP Drill Pipe Grade Reference

This page uses grade values as a data reference only. Selection by well depth, load, fatigue exposure or drilling environment belongs in the separate selection guide.

For grade-selection logic, see Drill Pipe Sizes, Grades & Connections: A Practical Selection Guide.

Drill Pipe Length Reference: R1, R2 & R3

Drill pipe is purchased by a specified length range rather than assuming every joint is identical. Confirm the required range and project-specific length tolerance in the purchase order.

How to Read One Drill Pipe Specification

A line such as 5 in × 19.5 lb/ft × S135 × IEU × NC50 × R2 contains several independent technical fields. Do not treat “5-inch S135” or “NC50” as a complete purchase description.

How to Use This Technical Data

The tables are designed for technical lookup, preliminary comparison and preparation of a configuration-specific inquiry. They do not prove interchangeability or establish permissible field operating torque by themselves.

• For replacement pipe, compare grade, connection, tool-joint OD, pin ID, bevel diameter, tong-space dimensions, upset-neck OD, hardbanding and overall length.
• For final production, use the approved Shangshanpetro datasheet, applicable API requirements and purchase order.
• For connection equivalence or NC / IF / FH / REG compatibility, use the dedicated connection guide rather than this data page.
• For choosing size, weight or grade for a drilling condition, use the selection guide.
