Where it fits
High-pressure or high-load well construction where the well design explicitly specifies P110 and confirms connection, collapse, burst and service-environment requirements.
API 5CT · OCTG grade reference
API 5CT P110 casing and tubing reference
API 5CT P110 casing is a grade-specific reference for engineering selection and RFQ preparation. HONGFENG verifies grade suffix, dimensions, connection, test requirements and documents for each order.

Grade scope
How to read API 5CT P110 casing
High-strength casing or tubing reference; the exact product form, weight, length, connection and service review are confirmed per order.
What not to assume
P110 is high strength but is not a default sour-service material. Higher strength does not mean that hardness, environmental cracking or connection performance can be ignored.

FAQ
API 5CT P110 casing
What are API 5CT P110 yield and tensile values?
The reference range is 758–965 MPa yield and minimum 862 MPa tensile. Dimensions, weight, connection and service conditions still control the finished product.
Is P110 suitable for sour service?
No blanket approval should be given. Sour service with H2S requires a separate material and connection review against the applicable project standard; P110 is not a default sour-service choice.
What should be included in a P110 casing RFQ?
Include OD, wall or weight, R1/R2/R3 length, coupling and thread, pressure and temperature, H2S/CO2, inspection, quantity, destination and required date.
