HYDROCARBON PIPELINE SEAL SOLUTIONS
Liquid hydrocarbon pipeline
Overview
At John Crane, we understand the importance of hydrocarbon pipeline integrity. A mechanical seal failure not only means production losses of up to millions of dollars per day but could also lead to long-term environmental consequences.
We help operators minimise risk by ensuring each pipeline seal matches the process conditions of your application.
Choosing the proper mechanical seal or secondary containment seal for a hydrocarbon pump is essential for preventing pipeline sealing emergencies.
Your selection should consider fluid type, viscosity, operating pressure and whether your system transports crude, refined products or multiphase liquids.
If you are unsure which sealing solution is the best fit for your pipeline, the questions below will help you.

Liquid filtration and seal support systems
Liquid filtration solutions
- Filters can be applied to almost any liquid application
- Filters in duplex configuration to ensure adequate, uninterrupted filtration of the process flow when changing the filter element
- Patented elements remove particle contamination and maximise reliable operation of the equipment
Seal support systems
- API Plan P53B: An accumulator-based seal support system that utilises a bladder to maintain system pressure to a dual-pressurised seal
- API Plan P54/P55: Provides a positive flow and pressure of barrier fluid to a dual-pressurised seal
- API Plan 54/P55 is typically preferred where flow and heat removal capacity exceed that of API Plan 53B

Common questions
What is a hydrocarbon pipeline?
A hydrocarbon pipeline is a dedicated system used to transport liquid or gas hydrocarbons, such as crude oil, refined products or natural gas, over long distances. These pipelines rely on specialised seals, containment systems and monitoring equipment to ensure safe, reliable and leak-free operation.
What is a pipeline insulator?
A pipeline insulator is a component used to electrically isolate sections of a pipeline, preventing corrosion caused by stray currents or galvanic contact between dissimilar metals. John Crane insulators help maintain pipeline integrity by reducing corrosion risk and supporting long-term reliability across demanding hydrocarbon transport systems.
What’s the best material to insulate pipes?
The best insulation material depends on temperature, fluid type and operating environment. Common choices include polyurethane foam, mineral wool and aerogel for high-efficiency thermal protection. John Crane recommends insulation solutions based on pipeline conditions to help maintain temperature stability and prevent energy loss in hydrocarbon transport.
