API 5CT P110 casing coupling is a connector for P110-grade casing used in high-pressure oil and gas wells. P110 is a high-strength steel grade defined by API 5CT, offering a minimum yield strength of 110,000 psi (758 MPa). It is heat-treated (quenched and tempered) for superior strength and toughness, making it ideal for high-pressure, high-stress environments.
P110 couplings are manufactured to API 5CT standards, ensuring quality, reliability, and interchangeability. They are commonly used in deep wells and harsh drilling conditions where exceptional mechanical performance is required. However, P110 is less resistant to corrosion, so it may require additional protection in corrosive environments.
