a Labels are for information and assistance in ordering.
b Nominal linear masses, threaded and coupled (Column 4) are shown for information only.
c The densities of martensitic chromium Steels (l80 Types 9Cr and 13Cr) are less than tHose of Carbon steels; The masses shown are therefore not accurate for martensitic chromium steels; A mass correction factor of 0.989 shall be used.
d Mass gain or loss due to end finishing; See 8.5.
e Drift diameter for most common bit size; This drift diameter shall be specified in the purchase agreement and marked on the pipe; See 8.10 for drift requirements.
f Based on 758 mPa minimum yield strength or greater.
g Based on 379 mPa minimum yield strength.
Premium connections are designed to provide a higher level of performance than standard connections. They are designed to reduce the risk of leaks and provide a stronger connection that can withstand higher pressures and temperatures. This makes them ideal for use in deep wells and other challenging environments.
Premium connections also provide improved torque performance, which helps to reduce the risk of galling and other issues that can occur when connecting and disconnecting the casing and tubing. This helps to reduce the amount of time and effort required to make the connection, which can save time and money.
Finally, premium connections are designed to be more resistant to corrosion and wear, which helps to extend the life of the casing and tubing. This can help to reduce the cost of Maintenance and Repairs, as well as the cost of replacing the casing and tubing.
Overall, using casing and tubing with premium connections can provide a number of benefits for oil and gas operations. The improved performance, reduced risk of leaks, improved torque performance, and increased resistance to corrosion and wear can all help to reduce costs and improve the efficiency of the operation.
