Midstream/Downstream — Processing, Piping and Refining
Due to the volatile and hazardous nature of midstream and downstream oil and gas materials, every pump, compressor, turbine and mixer depends on innovative engineered components to optimize safety and emission containment. John Crane engineers products specific to abrasive conditions, pressure changes, and multi-phase fluid properties to maximize uptime and minimize emissions. If service, repair or refurbishment are ever needed due to planned or unplanned maintenance, we also have 230 global rapid-response locations ready to dispatch specialized assistance at any time.
