Oil and Gas

In oil and gas applications, reliability and safety are essential. To support the industry’s highly regulated, mission-critical operations, John Crane offers a wide range of innovative services and applied engineering solutions. Our experienced sales and engineering staff help select, design and apply sealing systems for even the most challenging conditions, and John Crane products meet the highest industry standards for containment of fugitive emissions. We also have 90+ test rigs available to ensure components can operate with maximum reliability when subjected to specific environmental conditions. And with more than 200 global rapid-response locations, assistance is available whenever and wherever our customers need it.

Upstream — Oil and Gas Extraction

Offshore platforms and onshore oil and gas extraction facilities often operate in remote locations where storage space is limited and application conditions are extreme. And because equipment failure can have dire consequences — jeopardizing costs, environmental safety and energy resources — these mission-critical operations require reliable engineered components that can withstand extreme temperatures, high pressures, corrosion and erosion over a long period of time. John Crane not only engineers products with proven long-term success under these conditions; we also offer a wide range of assistive services that help maximize application reliability.

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 over 200 global rapid-response locations ready to dispatch specialized assistance at any time.
