Frequently asked questions
What does high-pressure equipment mean and from what values does it start?
There is no single limit accepted in all fields. In industrial practice, installations with hundreds of bar are considered high pressure, and those above 1,000 bar fall into the very high range, with thick-walled tubing and special joints. Not only the value matters but also the fluid: a compressed gas stores much more energy than a liquid at the same pressure and the same volume. For installations in the field of pressure equipment, PED 2014/68/EU applies, and the classification is established by the designer. Send us the working pressure and the fluid, and we will guide you towards the suitable type of equipment.
Why is a compressed gas more dangerous than a liquid at the same pressure?
A liquid is practically incompressible, so if a part fails the pressure drops very quickly and the energy released is small. A gas is compressed, and the stored energy is released on rupture in the form of a shock wave and projected fragments. For this reason pressure tests are usually carried out with liquid, and working with compressed gases requires additional protection: enclosures, delimited zones, safety valves and trained personnel. The safety details of a specific installation are established by the designer, according to the applicable rules.
Why does material compatibility matter for hydrogen and oxygen?
Hydrogen can penetrate some steels and embrittle them, especially under pressure and under repeated loading, so materials and treatments are chosen according to the recommendations for this gas. Oxygen supports combustion, and oils, greases and particles remaining in components can ignite in its presence under pressure, which requires specific cleaning and compatible materials. A fitting or a regulator suitable for nitrogen is not automatically suitable for these gases. State the exact gas in the request, and we check compatibility before proposing a model.
How do I identify a high-pressure part to be replaced if the nameplate is missing?
Start with the dimensions that do not change: the outside diameter of the tube or the thread type, the shape of the cone or of the seal, and the pressure marked on the body. Photographs from several angles, together with the fluid and the working pressure, help with identification. Do not fit a part just because the thread matches, since different families of connections can have almost identical threads but different cone angles or pressure ratings. If identification is uncertain, it is better to replace the components along the whole section of line with one uniform family.
What documents can I receive for public procurement or for the installation file?
Depending on the product and the brand, we can make available datasheets, declarations of conformity, material certificates and operating instructions, where the supplier provides them. For installations subject to PED 2014/68/EU, the file usually also includes the designer's documentation. State the requirements of the specification from the first request, including CPV codes and the documents required on delivery, so that we can prepare them together with the quotation and avoid later additions. We cannot issue documents that the manufacturer has not drawn up, but we tell you clearly what is available.
How long does delivery take and what do I send for a quote?
Send the fluid, the maximum working pressure, the flow rate or line size, the temperature, the connection type and, if you have it, the code from the nameplate of the existing equipment. For complete installations, a sketch of the line simplifies the quotation. Delivery takes 24–72 h when the item is available locally or at the supplier. To order, the lead time is usually 1–4 weeks, and depending on the brand and the specifications it may take longer, especially for equipment configured on request. We tell you the specific lead time before the order is confirmed.
