Nordstone Engineering Excellence
For over three decades, Nordstone has established itself as an elite global leader among heavy-industrial separator vessel manufacturers in Italy, serving critical process industries across Southern Europe.
Our comprehensive 20 years of experience in precision engineering allows us to construct high-performance pressure vessels engineered to isolate multiphase fluids under extreme operational constraints. Operating from our advanced fabrication facilities, our expert engineering teams build highly efficient, heavy-duty industrial separator vessels optimized for liquid-gas separation, multiphase oil-water-gas extraction, and down-stream chemical refining.
Every custom piece of process equipment we design incorporates advanced flow dynamics and state-of-the-art internal components—such as specialized vane packs, high-surface-area demister pads, and complex internal cyclonic structures.
This ensures maximize residue extraction while systematically protecting downstream mechanical infrastructure from moisture carrying and corrosive wear. By strictly complying with universal ASME Section VIII Div. 1 & Div. 2, API 12J, and European PED 2014/68/EU directives, Nordstone provides Italian energy, defense, and pharmaceutical operations with the rugged safety, technical reliability, and structural integrity needed for demanding, highly corrosive processing environments.
Frequently Asked Questions (FAQs)
1. What types of separator vessels does Nordstone manufacture for the Italian industrial market?
We design and fabricate a broad range of high-efficiency multiphase separation systems tailored to Italian engineering requirements. Our primary manufacturing portfolio includes:
- Two-Phase Separators: Optimized specifically for high-velocity liquid-gas separation.

- Slug Catchers: Heavy-duty vessel systems configured to capture unpredictable, high-volume liquid surges at pipeline terminals. nordstoneng.com
2. Which international and European design codes do your vessels comply with?
All processing equipment leaving our facilities satisfies rigorous global regulatory requirements. To serve the European and domestic Italian markets, we manufacture pressure equipment fully compliant with ASME Section VIII (Div. 1 and Div. 2), API 12J, CE Marking, and the European Pressure Equipment Directive (PED) 2014/68/EU.
3. What premium metallurgical grades do you use to combat high corrosion?
To ensure long-term structural survivability in hostile, sour gas, or saline conditions, we build custom separator units using premium heavy materials:
- High-tensile Carbon Steel (SA 516 Gr. 60/70) & Low-Temperature Carbon Steel (LTCS) nordstoneng.com
- Austenitic Stainless Steels (SS304, SS316, SS316L) nordstoneng.com
- Duplex & Super Duplex Stainless Steels for extreme chloride resistance nordstoneng.com
- High-nickel alloys (Inconel, Monel, Hastelloy) and specialized corrosion-resistant cladded overlay options. nordstoneng.com
4. Can Nordstone manufacture skid-mounted separator systems?
Yes. We specialize in producing fully integrated, turn-key skid-mounted separation packages. These modular units come complete with process piping, instrumentation, control valves, safety relief networks, and structural support frames pre-assembled, enabling rapid plug-and-play installation on-site.
5. What advanced separation internals do you integrate into your vessels?
To guarantee maximum mechanical efficiency and clear fluid streams, our custom internal configurations utilize:
- Inlet Diffusers & Vane Distributors: To dissipate fluid momentum and optimize initial bulk phase splitting. nordstoneng.com
- Demister Pads / Mesh Mist Eliminators: To catch sub-micron droplets from rising gas. nordstoneng.com
- Vane Packs & Cyclonic Internals: For high-velocity mist extraction without clogging. nordstoneng.com
- Weir Plates & Calm Baffles: To maintain steady, undisturbed liquid levels for clean water-oil separation. nordstoneng.com
6. Do you utilize modern digital simulation tools during the design phase?
Absolutely. Every unit undergoes intense structural and thermal evaluation using Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) software. This lets us visualize internal fluid trajectories, avoid flow channel short-circuiting, minimize structural fatigue points, and prove separation efficiency before manufacturing begins.
7. What testing and quality control protocols do you carry out?
Our strict quality management system includes standard and optional non-destructive examination (NDE) protocols executed by certified technicians:
- Full Radiographic Testing (RT) and Ultrasonic Testing (UT) on critical structural welds
- Magnetic Particle (MPI) and Dye Penetrant Testing (DPT)
- Hydrostatic pressure testing up to 200+ bar and pneumatic leakage assessments nordstoneng.com
- Full material traceability with EN 10204 3.1 Material Test Certificates (MTCs). nordstoneng.com
8. What are the typical pressure and temperature operational boundaries of your vessels?
Our custom production capabilities cover an extensive operational envelope. We build process units that comfortably operate from full industrial vacuum conditions up to ultra-high pressures of 200 bar, with design temperatures ranging from cryogenic processing levels of -50°C up to +400°C.
9. Which core industries in Italy utilize Nordstone separator equipment?
Our heavy-duty industrial vessels are relied upon across multiple Italian high-consequence fields:
- Upstream Oil & Gas exploration and gas processing plants nordstoneng.com
- Petrochemical refineries and chemical manufacturing facilities nordstoneng.com
- Naval defense applications and power generation facilities
- High-purity pharmaceutical processing and industrial solvent recovery.
10. How do Nordstone separator vessels protect downstream equipment?
By achieving superior liquid-gas extraction rates, our vessels remove liquid carryover from process gas streams. This keeps corrosive fluids, fine particulates, and liquid slugs out of downstream equipment like gas turbines, compressors, and high-precision boilers, preventing critical mechanical breakdowns.
11. Do your separator designs accommodate sour gas applications?
Yes. For applications processing hazardous, high-sulfur compounds, we engineer vessels in strict compliance with NACE MR0175 / NACE MR0103 standards. We utilize certified HIC (Hydrogen-Induced Cracking) resistant steels and high-alloy internal linings to prevent sulfide stress cracking.
12. Can your systems manage irregular fluid slugs or high foam levels?
Yes. Our processing equipment can be intentionally designed with added residence volumes to neutralize large liquid surges (slugs). We also integrate anti-foam internal configurations and mechanical breaking systems to destabilize chemical foaming and maintain reliable liquid level tracking.
13. What automation and instrumentation packages can be supplied?
We supply custom-configured instrumentation arrays, offering electronic transmitters, radar-guided or magnetic level indicators, pneumatic control valves, and integrated PLC/SCADA-compatible automation panels that allow local facility personnel to remotely track process dynamics.
14. What is the standard lifespan of a Nordstone industrial vessel?
By utilizing premium alloy selections, calculated corrosion allowances (typically 1 to 3 mm), precision welding procedures, and specialized protective coatings (such as high-performance glass flake or phenolic linings), our vessels are engineered for a standard operational life exceeding 20 to 30 years.
