Nordstone designs and manufactures custom high-pressure gas cylinders in Italy for hydrogen, nitrogen, oxygen, and liquefied gases. Each cylinder is built to ASME, API, ISO, and PED 2014/68/EU standards, fully tested, and delivered with a complete documentation package.
Industrial gases power oil and gas plants, shipyards, aerospace programs, and advanced manufacturing lines across Italy. Storing them safely under high pressure takes more than thick steel. It takes sound design, proven materials, and strict testing. Nordstone is one of the trusted high pressure gas cylinders manufacturers in Italy, with more than 20 years of experience in pressure vessel fabrication.
Engineered for Extreme Conditions
A high-pressure cylinder faces constant stress from internal pressure, temperature swings, and chemical exposure. Our engineers design every cylinder around these loads. We study your operating pressure, gas type, temperature range, and available space before drawing begins. The result is a cylinder shaped around your process, not a standard product that forces you to adjust your plant.
Pressure and Temperature Capability
Nordstone builds custom cylinders and vessels from full vacuum up to 100 bar as standard, and up to 200 bar or more where the application and code calculations allow. Our designs handle a wide temperature window, from cryogenic conditions near −50°C to process temperatures of +400°C. Where temperature control matters, we add heat tracing, heating or cooling jackets, or heavy-duty insulation blankets.
Materials Matched to Your Gas
Material choice depends on the gas and the environment. We work with traceable, certified materials, including:
- High-tensile carbon steel such as SA516 Grade 60 and 70
- Low-temperature carbon steel for cold-climate and cryogenic use
- Stainless steels such as SS304, SS316L, and SS904L
- Duplex, super duplex, Hastelloy, and titanium for aggressive media
For hydrogen storage, our engineers pick low-alloy or high-grade stainless steels and apply special welding procedures to reduce embrittlement risk. For sour gas service, our designs follow NACE MR0175 and ISO 15156 requirements.
Certified to European and Global Codes
Compliance protects both your people and your project approvals. Our facility holds ASME U and U2 stamps, along with API and ISO certifications. We also follow the European Pressure Equipment Directive 2014/68/EU, so every cylinder meets the expectations of Italian and EU authorities. This wide coverage means your equipment is accepted across projects in Italy and beyond.
Quality Checked at Every Stage
Each cylinder follows a documented quality assurance plan. Welds are examined through radiographic, ultrasonic, magnetic particle, and dye penetrant testing. We also carry out hydrostatic and pneumatic pressure tests and helium leak detection to confirm zero-leakage performance. During design, we use finite element analysis and computational fluid dynamics to remove stress concentration points. Together with precision automatic welding and stress-relieving heat treatment, these steps give each cylinder a long, reliable service life.
Cylinders, Cylinder Packs, and Skid Packages
Not every project needs a single cylinder. Nordstone builds standalone storage cylinders, manifolded cylinder packs, and fully modular skid packages. We group, interconnect, and assemble the cylinders into one factory-tested unit. This approach reduces on-site construction time and speeds up commissioning at your facility.
Surface Finishes for Every Sector
Operating conditions vary, and so do surface requirements. For offshore and outdoor use, we apply durable external coatings that resist marine exposure. For pharmaceutical and food-grade applications, we offer mirror-polished interiors, passivation, and electropolishing that meet GMP standards.
Industries We Serve in Italy
Our cylinders support oil and gas, petrochemicals, chemical processing, power generation, renewable energy, pharmaceuticals, marine engineering, and defence. Each sector has its own safety rules, and our engineers adapt every design to match.
