Today’s market demands complex processes that comply with stringent regulations governing midstream applications. Ashcroft have developed NACE MR0175/ISO1516-2009 compliant gauges, seals, transducers and switches designed to perform in oil and gas industry.

The need to optimize costs and uphold the highest standards of safety and environmental protection are uniform and constant. We have experience on field, understanding the complexity of oil and gas processes to provide solutions to reduce costs and ensure process and personnel safety.


On the tank car, at the transfer station and all along the pipeline, from the first pump station to the last, ECN has the answer for every midstream application. Our pressure and temperature instrumentation is the answer to monitor and control flow ensuring critical equipment and to assure staff are safe from over-pressurization and other challenges.
