Reliable Sealing Solutions for Liquid Hydrocarbon and Natural Gas Pipelines

With specialised midstream expertise, John Crane understands the importance of pipeline integrity. A mechanical seal failure can cause millions of dollars in daily production losses. It can also lead to long-term environmental impact. Our midstream sealing solutions include a wide range of specialised dry gas seals and systems, pump seals and couplings that help increase reliability and efficiency across key midstream applications. John Crane has installed more than 3,000 dry gas seals in centrifugal compressors across 305,000 miles of gas transmission pipelines in the U.S. alone. 

As John Crane enters its second century of technology leadership, we’re committed to pioneering innovations that address tomorrow’s midstream challenges today. That includes numerous recently introduced technologies for liquid hydrocarbon and natural gas pipeline operations.
