Outer Diameter

The outer diameters (OD) of OCTG pipes are standardized to ensure compatibility and interchangeability between different manufacturers and applications. The standardization of outer diameters for OCTG is primarily governed by industry organizations such as the American Petroleum Institute (API) and the International Organization for Standardization (ISO).
The API has developed various specifications and standards for OCTG pipes, including API Specification 5CT, which covers the technical requirements for casing, tubing, and line pipe. Within API 5CT, specific dimensions for outer diameters are defined based on the pipe’s intended use and size range.
The most common standard OD’s for tubing are as follows: 2-3/8”, 2-7/8”, 3-1/2”, 4”, and 4-1/2”
The most common standard OD’s for casing are as follows: 4-1/2”, 5”, 5-1/2”, 6-5/8”, 7”, 7-5/8”, 7-3/4”, 8-5/8”, 9-5/8”, 10-3/4”, 11-3/4”, and 13-3/8”
It’s important to note that these sizes are examples and not an exhaustive list. The exact range of standard outer diameters may vary based on specific API specifications or other industry standards. Additionally, there may be non-standard or custom sizes available based on project requirements.
