  1. Challenges with Galvanic Corrosion in a Pipeline

    The presence of galvanic corrosion within an industrial pipeline system should not be underestimated, taken seriously and not ignored. Galvanic corrosion will eventually lead to potential dangerous results characterized by the type of failure within the pipeline. In order to make the correct dielectric union choice, it is critical to fully understand the environmental conditions the dielectric union will be subjected to.

    HART has engineered a solution to address these common failures in the industry. HART manufactures a high-quality dielectric union that is designed to prevent galvanic corrosion when transitioning between two dissimilar metals and handles system pressures to 3000psi (standard) and temperatures to 400F while providing excellent chemical resistance to both polar and non-polar fluids and gases. Our insulated unions work by introducing a proprietary dielectric insulation which acts as a “protective barrier” between the two dissimilar metals. This proven technology offers electrical insulation of over 600V per mil of thickness, which prevents the flow of current between them and thereby stops the corrosion from occurring.

  3. A Greener Future

    Benefits of HART unions in green hydrogen infrastructure:

    Repair & Maintenance Efficiency:

    In pipeline damage or maintenance requirements, pipe unions allow for isolating and replacing specific sections without affecting the entire pipeline system. This reduces downtime during repairs and maintenance activities, ensuring a continuous supply of green hydrogen.

    Flexibility & Scalability:

    Green hydrogen infrastructure is expected to expand rapidly as the demand for hydrogen increases. Pipe unions offer the flexibility to easily add, remove, or modify pipeline sections. As new production facilities or end-users come online, unions allow quick adjustments to the pipeline network, ensuring a scalable and adaptable hydrogen distribution system.

    Material Compatibility:

    Green hydrogen systems may utilize different types of pipelines made from various materials, including steel, stainless steel, or specialized materials designed for hydrogen transport. Pipe unions allow for connections between different materials, ensuring compatibility and reliable hydrogen transfers while maintaining structural integrity.

    Easy Installation & Maintenance:

    Pipe unions allow for easy and quick installation and disassembly of hydrogen pipelines. This is especially beneficial in green hydrogen projects, where pipelines may need to be set up in various locations to transport the produced hydrogen from the generation site to the distribution or storage facilities. Unions enable pipeline sections to be connected and disconnected without requiring extensive welding or cutting, making installation and maintenance more efficient.

    Leak Prevention & Safety:

    Properly installed pipe unions with appropriate seals and fittings help minimize the risk of leaks, ensuring the safe transportation of hydrogen. Hydrogen is a highly flammable gas, so the integrity of the pipeline connections is critical to prevent any potential leaks that could lead to safety hazards.

  5. Did You Know – HART offers high-temperature steam unions!

    Did you know…

    ….that HART Industrial Unions now offers high-pressure / high-temperature resistant pipe unions that can withstand 1400°F for hydrocarbon and superheated steam service?

    Unions containing spiral wound gaskets can be supplied to meet national standards such as MSS-SP-83 and ASME B16.20. The pipe union design is similar in principle to flange joints but outperforms the difficulties associated with standard “ground-joint” pipe unions. This is accomplished by forming the seal with replaceable spiral wound gaskets without a ground joint (ball & cone). Our flat-face design provides turbulence-free fit across seats. This design is ideal where piping requirements dictate the need for a flat face seal to make and break the pipeline.

    HART Industrial spiral wound gasket unions are engineered to provide Class 3000 Service in extreme temperatures and environmental conditions. Operational conditions such as temperature, pressure, and media will dictate your application’s proper spiral wound gasket selection.

    Application & Performance:

    • Standard graphite spiral wound gasket union
      • Resistant to 850°F (450°C) for hydrocarbon, superheated steam service, and more!
    • High-Temperature Options Available!
      • Engineered solutions for 1400°F (760°C) and higher, including turbine and energy.
    • Available in various materials including 316 Stainless Steel, Monel, Hastelloy, Inconel, and more!
