NOTE See also Figures D.1, D.2, and D.3.
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.
Testing oil casing one by one ensures that each casing is up to the highest standards. This helps to ensure that the casing is strong enough to withstand the pressure of the oil and gas that will be flowing through it. It also helps to identify any potential weak spots or defects that could lead to a leak or other issue.
Testing each casing individually also helps to ensure that the casing is properly sealed. This helps to prevent any oil or gas from escaping, which can be a major safety hazard. It also helps to ensure that the casing is properly aligned and that it is able to withstand the pressure of the oil and gas.
Applications:
For tubular heat exchangers,condensers,and similar heat transfer apparatuses.
Size (mm):
O.D.: 6.0~168.0; W.T.: 1~15; L: max 12000
Finally, testing each casing one by one helps to ensure that the casing is properly installed. This helps to ensure that the casing is properly connected to the other components of the system, such as the valves and pumps. This helps to ensure that the system is running as efficiently as possible.
