The following formulas are used in the ASME Code Section VIII, Division 1 for determining wall thickness: Wall thickness—cylindrical shells Figure 12-1 defines the various…
The maximum allowable stress values to be used in the calculation of the vessel’s wall thickness are given in the ASME Code for many different…
The design pressure for a vessel is called its “Maximum Allowable Working Pressure” (MAWP). In conversation this is sometimes referred to simply as the vessel’s…
The maximum and minimum design temperatures for a vessel will determine the maximum allowable stress value permitted for the material to be used in the…
One of the growing environmental concerns for both new and existing reciprocating compressor installations is fugitive emissions. Fugitive emissions are the leakage of volatile organic…
Reciprocating compressors are generally classified as either low-speed (integral) compressors or high-speed (separable) compressors. API has provided a standard and specification for each type of…
Satisafactory compressor installations many times depend on how well the foundation or support structure was designed. An inadequate foundation design can result in equipment damage…
Because of the reciprocating action of the piston, care must be exercised to size the piping to minimize acoustical pulsations and mechanical vibrations. As a…
The flow required to lubricate the packing and cylinders is quite small, and the pressure necessary to inject the lubricant at these locations is quite…
The frame lubrication system circulates oil to the frame bearings, connecting rod bearings, crosshead shoes, and can also supply oil to the packing and cylinder…
