Frequently asked questions
What does “cryogenic” mean and from what temperature do we talk about cryogenic equipment?
In industrial practice, the cryogenic range usually begins below about minus 150 °C (some definitions use minus 180 °C), the range in which the boiling points of nitrogen, oxygen, argon and methane lie. Liquid nitrogen boils at about minus 196 °C, oxygen at about minus 183 °C and liquefied natural gas at about minus 162 °C. At these temperatures many ordinary materials become brittle, elastomers stiffen and thermal insulation becomes essential. For this reason the equipment is specially designed, with austenitic stainless steels, aluminium or brass, with suitable seals and, where necessary, with vacuum insulation.
What data should I send to receive a quote for cryogenic equipment?
The most important is the liquefied fluid, because the materials, cleanliness and safety requirements depend on it. Then state the maximum working pressure, the flow rate or capacity required, the connection diameter and the installation conditions, for example indoors or outdoors, hazardous area or confined space. If you are replacing existing equipment, send the product code or a photograph of the nameplate. With this information we can check the fit and reply with a technical quotation, without you losing time on clarifications.
Why does cleanliness matter for oxygen service in cryogenic equipment?
Oils, greases and fine particles can ignite in the presence of concentrated oxygen, especially under pressure, and ignition in a valve or a pump can have serious consequences. For this reason, components for oxygen are degreased, checked and packed protected, and the lubricants and seals used must be oxygen-compatible. Equipment previously used with another fluid is not switched to oxygen without complete cleaning. When ordering, state the fluid from the start, so that delivery is made in the right condition.
What regulations apply to cryogenic pressure equipment?
Pressure equipment falls under the European PED Directive 2014/68/EU, which sets the requirements for design, manufacture and conformity assessment. For cryogenic valves and vessels there are dedicated European standards, for example EN 1626 for valves intended for cryogenic service and EN 13458 for stationary vacuum-insulated cryogenic vessels. If the fluid is flammable, the installation area may also require equipment compliant with the ATEX Directive 2014/34/EU. The specific documents depend on the product and the application, which is why we confirm them on the basis of the specifications sent.
What risks arise when working with liquid nitrogen or other liquefied gases and how are they reduced?
The main risks are frostbite from contact with the liquid or cold surfaces, asphyxiation by vaporised gas displacing the oxygen in the air, and overpressure in closed sections. They are reduced by cold-protection equipment, good ventilation in storage spaces, oxygen detectors in small rooms, relief valves on lines that can be isolated, and clear working procedures. For oxygen there is the added risk of ignition, and for hydrogen and natural gas, the risk of explosion. Training of personnel is just as important as the equipment.
How long does delivery take and what happens when the equipment is not available locally or at the supplier?
Delivery usually takes 24–72 h when the item is available locally or at the supplier. Special cryogenic equipment, for example pumps, large-capacity vaporisers, tanks or vacuum-insulated lines, is brought in to order, usually in 1–4 weeks, and depending on the brand and the specifications the lead time may be longer. In the quotation we send, we give you the estimated lead time for the specific case, so that you can plan your work. If you have a scheduled shutdown, state the date on request.
