microPIMS Has Gone Global!

microPIMS® Has Gone Global! When microPIMS first debuted, it was only available in North America: US, Mexico and Canada. But we’re proud to announce that our wireless, battery-powered, non-intrusive corrosion and erosion monitoring system is now available internationally. microPIMS Global Solutions follows the LoRa Alliance frequency protocol and is now available wherever LoRa is approved.

Atmospheric Distillation Tower

Overview Customer replaced lines on Atmospheric Tower due to amine corrosion (Chloride & HCL) issues. Installed sensors in TML ports circumferentially in areas where corrosion was seen previously to monitor corrosion rates. Application 24” line … insulated w/ TML ports, ~220F Product Used 1 smartPIMS cellular systems w/ 8 dual element probes Installation performed by

Distillation Unit

Overview Customer was interested in monitoring corrosion on their distillation unit piping to compare 12:00 & 6:00 areas. Application 6” line, operating at <620F Product Used smartPIMS cellular w/ HT probes 1 smartPIMS cellular systems w/ 2 HT probes Monitoring interval: every 6 hours HT probe mounted temporarily as they will be moving them to

Crude Tower & Overhead Lines

Overview Customer had defined areas located on and around the crude tower & overhead lines (vessels & piping) when they wanted to monitor. Installed on new piping as previous assets failed earlier than operations team expected. Non-invasive UT probes were installed at strategic monitoring locations to identify areas which previously or were likely to experience

Steam Line

Overview Trial of system on HT and dual system on steam line to evaluate resolution, repeatability, and accuracy. Customer wanted to validate cellular connectivity, probe performance, and data management using webPIMS. Application 6” steam line, operating at ~200F Thickness ~0.350” Product Used Custom built smartPIMS Cellular smartPIM w/ 4 duals and 4 HT probes Monitoring

Hydrodesulphurizer (HDS)

Overview Customer had issues for many years with piping circuit including a small leakage resulting in an unplanned maintenance outage. Piping was eventually upgraded from carbon steel to stainless steel and various sections have been replaced multiple times. Large portion of line inaccessible requiring scaffolding or other access. Two units were installed at various points

Distillate Hydroprocessing Unit (DHU)

Overview After replacing piping during a unit re-vamp, slight process changes seemed to cause significant corrosion to an inaccessible location. However, due to the early life of piping (<3 yrs. old) and limited data available, skepticism was raised from customer about the true corrosion rate of the piping. A semi-permanent platform was then built to

Crude Unit

Overview Section of crude unit had experienced stress corrosion cracking on the internal stainless steel cladding. The customer replaced with weld beads on ID and was performing temporary AUT scans to monitor for low spots. Installed sensors were put on both low spots as well as “miscellaneous” areas to gauge corrosion rate data. Application Crude

Sulfuric Acid Alkylation Unit

Overview Customer had two significantly low spots & six moderately low sports on Sulfuric Acid Alkylation Unit. Was sending UT technician to check weekly status of pitting. Installed sensors to monitor for pit growth and to ensure unit could last until planned outage 18 months away. Accelerated sulfuric acid (low PH) excursions & not enough

Crude Overhead Line

Overview Customer installed new overhead lines connecting units. Lines located in un-accessible areas and wanted data on corrosion rates and inspection needs. Customer installed permanently installed UT sensors to monitor pipe intrados, extrados, top & bottom locations Application Crude Overhead Line 300F-100F 12” Sch. 40 … all nominal wall thickness .4” +/- 12% Product Used
