if you mean a cylinder with a hole through it like a pipe or tube, then it's pi x (Od2 - id2)/4 x h Od = outer diameter id = inner diameter
wall thickness of pipe is (OD - ID) /2
it will vary by Tool Joint OD and ID. FYI 7"OD x ID 4" HT55 is 52,600 Ft lbs
If you Google "mild steel density" you find that a value of 7.85 is not uncommon.If you calculate the volume of steel in your pipe (Google "volume of cylinder") calculate the volume of the OD cylinder and subtract the volume of the ID cylinder and multiply that by the density you get the mass of the pipe multiply that by the gravitational constant (Google "gravitational constant") of your location to get the weight.Or you could just Google "ms pipe weight calculator" (see the Sources and related links below) find the pipe shape and put in your values, hit "Calculate" and get the answer 34.6889 lbs (which has far too many significant figures (converted to kg by Google as 15.7 kg still with one significant figure too many as two of the original dimensions only had two significant figures)
Based on the NPS and schedule of a pipe, the pipe outside diameter (OD) and wall thickness can be obtained from reference tables such as those below, which are based on ASME standards B36.10M and B36.19M. For example, NPS 14 Sch 40 has an OD of 14 inches and a wall thickness of 0.437 inches. However the NPS and OD values are not always equal, which can create confusion.For NPS â…› to 12 inches, the NPS and OD values are different. For example, the OD of an NPS 12 pipe is actually 12.75 inches. To find the actual OD for each NPS value, refer to the tables below. (Note that for tubing, the size is always the actual OD.)For NPS 14 inches and up, the NPS and OD values are equal. In other words, an NPS 14 pipe is actually 14 inches OD.The reason for the discrepancy for NPS â…› to 12 inches is that these NPS values were originally set to give the same insidediameter (ID) based on wall thicknesses standard at the time. However, as the set of available wall thicknesses evolved, the ID changed and NPS became only indirectly related to ID and OD.For a given NPS, the OD stays fixed and the wall thickness increases with schedule. For a given schedule, the OD increases with NPS while the wall thickness stays constant or increases. Using equations and rules in ASME B31.3 Process Piping, it can be shown that pressure rating decreases with increasing NPS and constant schedule.[note 1]
if you mean a cylinder with a hole through it like a pipe or tube, then it's pi x (Od2 - id2)/4 x h Od = outer diameter id = inner diameter
wall thickness of pipe is (OD - ID) /2
id means inside diameter, od means outside diameter, copper pipe and tubing is measured by the od, therefore the od the pipe or tubing will be the same as the id of the fitting
The ID of a pipe (inner diameter) can be calculated by subtracting the pipe's wall thickness from its outside diameter. The formula is ID = OD - 2*WT, where ID is the inner diameter, OD is the outer diameter, and WT is the wall thickness of the pipe.
assuming it's hollow. 10.68*ID*(OD-ID)
it will vary by Tool Joint OD and ID. FYI 7"OD x ID 4" HT55 is 52,600 Ft lbs

The bearing number can be checked out depends on the size of ID (Inner Diameter), OD (Outer Diameter) and H (Height) of this bearing.
it means outside diameter as opposed to id which is internal diameter
The prefix od- otherwise known as ob- means toward, against, or completely.
