Cryoline gas tungsten arc welding

Find out about our Cryolines

We design and produce super-insulated pipes for cryogenics using high vacuum

Designed for the transportation of LIN, LOX, LAR, LNG, LHe, and LH2, our pipe systems for the transportation of cryogenic liquids offer a good solution against the entry of heat and gasification due to environmental factors during transfer between cold points.

At our workshop, we produce pipes, purgers, phase separators, and high tech fast cooling systems adapted to the needs of each project.

A wide range of industrial sectors, ranging from the production of liquid gases or bunkering of LNG to cryobiology, aerospace, food, and transport companies place their trust in Cryospain as their cryogenic technology partner.

Conversion of ships to LNG

In virtue of the implementation of regulation IMO 2020,more and more companies are opting to convert the engine and fuel systems of their ships to LNG. This commitment to more sustainable technology from an environmental point of view also implies considerable economical savings, due to the lower cost of the fuel.

At Cryospain we carry out the mechanical and thermal design, the manufacturing, and the commissioning of these systems following the strictest quality standards and in accordance with the quality certificate of the applicable maritime classes.

You can see the LNG ship conversion projects we have participated in our blog section.

Accessories

Flexible vacuum-insulated pipe

  • This design allows certain flexibility during the installation, provided a maximum bend radius is established beforehand.
  • Wide range of diameters, longitudes, and types of connections adaptable to the different situations.

.

Vacuum purger

  • This consists of a vacuum suction device that vents the accumulated gas.
  • It accelerates the cooling adjustments and prevents the accumulation of gas during periods of non-consumption.
  • Installed at the highest point of the installation.
  • Can be connected to the Johnston coupling built in to the pipe.

Vacuum-insulated phase separator

  • This ensures a constant level of liquid at a constant pressure, evacuating the gas generated.
  • Automated by the pressure control and liquid level.

    Gas trap

    • Compact vacuum-insulated system equivalent to a siphon that minimizes gasification when the gas is not consumed.
    • Prevents the formation of ice when there is a vertical section before the connection points, reducing losses of liquid.

    Logistics

    • Detailed 3D models for large loads.
    • Transportation, loading, and care instructions for the assembly equipment.
    • Transportation using a truck or STD container.
