It has a diameter of 9 5/8 inches, which makes it suitable for a wide range of applications. This size is commonly used in oil and gas drilling operations, where large volumes of oil and gas need to be extracted from the ground.

The LTC end of the API-5CT J55 Coupling is another important aspect to consider. LTC stands for Long Thread Coupling, and it is a type of connection that provides a tight seal and prevents any leakage. This type of coupling is commonly used in high-pressure and high-temperature applications, where a secure connection is crucial.

a In case of dispute, laboratory Rockwell C hardness testing shall be used as the referee method.
b No hardness limits are specified, but the maximum variation is restricted as a manufacturing control in accordance with 7.8 and 7.9.
c For through-wall hardness tests of grades L80 (all types), C90, T95 and C110, the requirements stated in HRC scale are for maximum mean hardness number.

The API-5CT J55 Coupling is made from J55 grade steel, which is known for its excellent mechanical properties. This steel grade has a high tensile strength and good resistance to corrosion, making it suitable for use in harsh environments. It is also easy to weld and has good formability, allowing for easy installation and maintenance.

In addition to its size and material, the API-5CT J55 Coupling also meets the stringent requirements set by the API. This ensures that the coupling is manufactured to the highest standards and will perform reliably in the field. The API sets guidelines for the design, manufacturing, and testing of oilfield equipment, including couplings, to ensure the safety and efficiency of operations.
