We have developed a program which calculates the required pressure at the pig launcher for pigging system of the pipe line. Pig cleaning (pigging) means to clean the internal pipeline or to replace fluid A with fluid B in the pipeline by pushing a pig between the fluid A and B.  We believe that by using our program the required pressure to transfer the pig can be obtained in advance, which will be useful to planning the system constitution and its operation.

Our program is also designed, to fit a number of various cases such as flashing of gas pipeline, emptying a pipeline with air, cleaning with air, water or oil, replacing with a different fluid, hydrostatic testing operations to allow the pipeline to be filled with water. Furthermore this program is capable of handling the control pressure of the pig receiver.

If you are interested in our program or need to do pressure calculation for your pig cleaning, please contact us.
