PACKING CASES

CPE delivers wide range of packing cases designs, according the type of gas, rod linear speed, gas pressure and temperature, type of lubrication etc.

MOST USUAL PACKING CASES DESIGNS:

-       WITH LEAKED GAS RECOVERY, mainly for process gases (flammable, sour, toxic, wet or costly gases).

-       WITH OR WITHOUT LUBRICATION according to the process specifications or as requested by the user.

-       WITH INTERNAL COOLING. The cooling of the packing cases is particularly recommended when working dry or at very high pressures.

-       WITH INERT BUFFER GAS (in accordance to API 618), to minimize residual leakage of the process gas.  The packing case is equipped with a chamber into which is introduced an inert gas (usually nitrogen) at a higher pressure than the venting pressure.

-       WITH INERT PURGE GAS (in accordance to API 618). This alternative is based on the same principle as the inert buffer gas, in this case, however, the packing case has an inert gas inlet and outlet (there is only an inlet for the buffer gas).

-       WITH OIL RECOVERY in the case of combined packing – oil wiper cases.
