API OIL COUNTRY TUBULAR GOODS
Structural and pressure integrity throughout the well.
Casing is installed in successive strings to stabilize the wellbore, isolate formations, protect freshwater zones and provide a pressure-containing barrier for drilling, completion and production. Selection is governed by the well design—not by outside diameter alone.
OAK PIPE coordinates casing, couplings, pup joints, connection requirements, inspection and export delivery against the customer’s casing program and purchase specification.
Temperature, pressure, H₂S, CO₂, chlorides and completion fluids.

SUPPLY OVERVIEW
Typical casing specifications.
The table supports preliminary procurement. Final availability, tolerances and compliance are confirmed against the requested edition, size, mass, grade and connection.
| Primary standard | API Spec 5CT / ISO 11960; API Spec 5B for API threading and gauging |
|---|---|
| Typical outside-diameter range | 4½ in to 20 in (114.30–508.00 mm), subject to grade, mass and manufacturing route |
| Common grades | H40, J55, K55, N80-1, N80-Q, L80-1, C90, T95, P110 and Q125; alloy/special-service grades by review |
| Manufacturing route | Seamless or electric-welded where permitted by the applicable product specification and order |
| Length ranges | Range 1: 16–25 ft; Range 2: 25–34 ft; Range 3: 34–48 ft (nominal range references) |
| API connections | STC (Short Round), LTC (Long Round) and BTC (Buttress) |
| Other connections | Selected premium or special connections, subject to authorization, compatibility and technical review |
| End supply | Threaded and coupled or plain-end as specified; thread protectors fitted for handling and shipment |
| Surface / protection | Bare, mill coating or order-specific preservation; internal options reviewed by application |
| Marking & traceability | Order-specific marking, heat / lot traceability and bundle identification |
Note: This is a capability overview, not a dimensional acceptance table. Purchase-order requirements and the governing standard take precedence.
SIZE & MASS SELECTION
Casing size and mass selection table.
Filter the complete 106-combination table by outside diameter, then compare nominal mass, wall thickness, inside diameter, drift and connection-mass values.
How to use this table
- Select the required outside diameter from the casing programme.
- Match nominal mass or wall thickness to the design load case.
- Then define grade, connection, length, service condition and inspection scope.

A dash means that the corresponding connection-mass value is not listed for that size and mass combination. Final grade, connection, length, inspection and delivery requirements are confirmed in the quotation and order documents.
MATERIAL SELECTION
Common API casing grade families.
Minimum yield values below are grade identifiers for initial comparison. Chemical composition, heat treatment, hardness and complete mechanical-property requirements remain governed by the applicable standard and order.
| Grade family | Specified minimum yield | Procurement context |
|---|---|---|
| H40 | 40 ksi / 276 MPa | Selected lower-strength applications; availability is size dependent. |
| J55 / K55 | 55 ksi / 379 MPa | Common casing grades for conventional well programs. |
| N80-1 / N80-Q | 80 ksi / 552 MPa | Higher-strength options with different delivery conditions. |
| L80-1 / L80-9Cr / L80-13Cr | 80 ksi / 552 MPa | Controlled-strength family; alloy variants require service review. |
| C90 | 90 ksi / 621 MPa | For specified well conditions subject to hardness and test requirements. |
| T95 | 95 ksi / 655 MPa | Higher-strength controlled grade for selected demanding service. |
| P110 | 110 ksi / 758 MPa | High-strength casing for deeper or higher-load well programs. |
| Q125 | 125 ksi / 862 MPa | High-strength grade requiring detailed design and specification review. |
CONNECTION SYSTEM
The connection is part of the pressure barrier.
Connection selection considers tensile efficiency, sealing demand, torque, clearance, running practice and compatibility with the well design.
STC
Short Round Thread CasingA common API round-thread option for suitable conventional requirements.
LTC
Long Round Thread CasingLonger API round-thread engagement for the applicable casing sizes and loads.
BTC
Buttress Thread CasingAPI buttress-profile connection commonly selected where higher axial efficiency is required.
Premium / Special
Project selectedMetal-to-metal sealing, gas-tight or high-torque requirements are reviewed case by case.
API BUTTRESS CASING CONNECTION
BTC geometry and gauging require controlled inspection.
API Spec 5B defines the applicable thread dimensions, tolerances, gauges and inspection practice. The exact standard edition and size-specific acceptance table must be stated in the order.
Thread form
Asymmetric buttress profile with five threads per inch. OAK working data records a 3° load flank, 10° stabbing flank and nominal 1.575 mm thread height.
Element inspection
Pitch, thread height, taper, profile, complete thread length and visual condition are checked with the applicable instruments and calibrated gauges.
Functional gauging
Working ring gauges are used for external threads and working plug gauges for internal coupling threads. Stand-off is evaluated against the applicable API 5B procedure.
Standard API BTC is not presented as a premium metal-to-metal seal or an independent torque-shoulder connection. Gas-tight, metal-to-metal sealing and secondary-shoulder requirements belong to separately qualified special connections.
CASING PROGRAM
Typical positions in the well.
The casing string and design loads determine grade, wall thickness, connection and inspection—not the application name alone.
Conductor Casing
Supports the upper wellbore and provides the initial structural foundation.
Surface Casing
Protects shallow formations and supports pressure-control equipment and subsequent strings.
Intermediate Casing
Isolates troublesome formations, pressure transitions or unstable intervals.
Production Casing
Forms the principal well barrier across the producing interval and supports completion operations.
Liner
A non-surface-reaching string used to isolate selected intervals while managing cost and clearance.
Tieback / Special Strings
Configured around remediation, completion or project-specific well-integrity requirements.
DEMANDING SERVICE
Requirements beyond standard API casing.
High-collapse, sour-service, corrosion-resistant, thermal and low-temperature requirements need additional engineering review. OAK PIPE evaluates the requested performance, material route, connection and verification plan with suitable manufacturing resources.
