Intelligent pigging

AJAKS offers comprehensive mechanical decoking and inspection of refinery fired heaters and pipelines using low-pressure intelligent pigging.

According to our customers we have the largest equipment base in Europe which enables us to clean several furnaces at multiple sites simultaneously. In addition we can significantly shorten the cleaning proces and thus reduce furnace downtime by operating several piging machines in paralel.

Within the scope of industrial pigging we offer mechanical decoking of refinery fired heaters and pipelines as well as removal of other types of heavy deposits, along with computerized recording of the cleaning proces and final report of obtained results. Our offer includes also uni-directional pigging and gas pigging. All these operations are carried out in a closed cycle and the waste generated during cleaning process is disposed of in compliance with applicable regulations and the highest safety standards.

Upon completion of the cleaning process, at the client’s request we perform inspections of refinery furnaces using intelligent pigging.

Intelligent pigging inspection includes wall thickness measurements, identification of any damages like dents, bulges, pitting, cavity, ovality etc. and assessment of the technical condition of furnace coils enabling proper selection of maintenance measures.

Regular inspections extend service life of the furnace and reduces the risk of damage and emergency Shutdowns. Intelligent pigging is a non-invasive and highly precise alternative to non-destructive testing methods. The application of such inspection minimises furnace downtime and optimises processes related to production, maintenance, and overhauls.
