Nordstone is an industry-leading manufacturer of high-performance Bag Filter Vessels and premium filtration & separation vessels in the UAE.
Backed by 20 years of experience, we specialize in designing and manufacturing custom industrial vessels engineered to handle the most demanding heavy-duty fluid treatment applications. Operating from our state-of-the-art facility, our expert engineering team delivers custom, certified pressure vessels capable of withstanding extreme pressures, harsh operating temperatures, and highly corrosive environments. Every single industrial bag filter housing we produce adheres strictly to international safety benchmarks, including API, ASME Section VIII Div 1, and ISO certifications.
Whether you require high-capacity duplex arrangements for continuous processing or specialized single-bag liquid filtration units, our systems optimize industrial fluid flow, guarantee low clean pressure drops, and protect downstream equipment from damaging particulate contamination across the Oil & Gas, marine, and petrochemical sectors.

Frequently Asked Questions
1. What are the engineering standards applied to Nordstone Bag Filter Vessels manufactured in the UAE?
Every industrial filtration and separation vessel is designed, engineered, and certified according to standard ASME Section VIII Division 1, along with applicable API and ISO quality assurance frameworks. This ensures compliance with UAE industrial safety mandates and international codes for pressurized systems.
2. Which materials of construction (MOC) do you offer for corrosive chemical environments?
We provide a diverse metallurgy selection depending on your fluid characteristics, including:
- Carbon Steel and Mild Steel (with optional FRP, rubber, or PTFE linings)
- Stainless Steel (SS304, SS304L, SS316, SS316L)
- High-grade Duplex Stainless Steel (Duplex 2205) for marine and highly corrosive applications.
3. Can your filtration vessels handle high-temperature and high-pressure applications?
Yes. Leveraging our 20 years of manufacturing experience, our vessels are robustly engineered with precise mechanical calculations to remain structurally sound under high design pressures and elevated process temperatures up to 250°C, specifically matching the volatile parameters found in local petrochemical plants.
4. What is the typical operational difference between a single-bag and a multi-bag vessel configuration?
- Single-Bag Vessels: Ideal for batch operations, lower flow rates, or pilot systems where processing can be temporarily paused for bag replacement.
- Multi-Bag Vessels: Designed for high-volume industrial processing (housing up to 20 or more bags within a single tube sheet), distributing heavy particulate loads to maximize dirt-holding capacity and increase run times between change-outs.
5. Do you offer continuous-operation or duplex bag filter systems?
Yes, we manufacture Duplex Bag Filter Systems. These setups feature parallel vessel configurations connected by a centralized 2-way or 4-way valve control manifold. This layout allows process fluids to be seamlessly diverted to the secondary vessel while the primary side undergoes maintenance or bag replacement, preventing costly unscheduled plant shutdowns.
6. What standard bag sizes and flow capacities can your housings accommodate?
Our flexible industrial housings support industry-standard bag diameters (typically 4” and 7”) and lengths varying from 10”, 17”, to 32”. Our custom process engineering capabilities allow us to build massive multi-bag systems capable of managing massive flow rates exceeding 2500 m³/Hr.
7. What is the recommended clean pressure drop and change-out threshold for these vessels?
Our optimized fluid dynamics ensure a remarkably low initial pressure drop across clean filter bags—often registering around 0.05 Kg/cm² (g). To ensure optimal system protection and prevent element rupture, we recommend scheduling an element replacement once the differential pressure drop reaches 0.8 Kg/cm² (g).
8. Can these vessels be customized with advanced quick-opening closures for minimal downtime?
Absolutely. To minimize maintenance windows, our vessels can be outfitted with specialized quick-opening closure mechanisms, such as heavy-duty swing eyebolts, tri-clover clamps, or counterweighted davit arms for quick, tool-free access to internal components.
9. Do your bag filter housings feature positive sealing mechanisms to prevent fluid bypass?
Yes. Our vessels integrate precision-machined positive sealing lips and compressed O-ring seating arrangements (utilizing Viton, EPDM, or Buna-N). This design feature guarantees zero fluid bypass or contaminant migration, ensuring that 100% of the untamed fluid passes directly from the inside to the outside of the filter media.
10. Are Nordstone filtration vessels suitable for high-viscosity industrial fluids?
Yes. Thanks to our spacious internal chamber designs and low-resistance flow channels, our separation vessels maintain high throughput rates and efficient particulate separation even when handling high-viscosity process fluids, oils, cutting fluids, and heavy refinery intermediates.
11. Can magnetic separations be integrated inside the bag filter vessel?
We can supply highly customized filtration units equipped with integrated, high-intensity permanent magnetic assemblies. This dual-action system captures heavy ferrous contaminants, metal scales, and fine mill chips before they reach the fabric bag, greatly extending the operational life of your consumables.
12. Do you manufacture specialized process skids that incorporate your filtration vessels?
Yes. As a comprehensive engineering and fabrication partner in the UAE, we build fully integrated, pre-piped modular filtration process skids. These plug-and-play packages combine our vessels with pumps, instrumentation, differential pressure transmitters, and isolation valves on a rugged steel structural frame.

13. What quality control testing protocols do you execute before shipping a vessel?
Every pressurized unit undergoes non-destructive testing (NDT), including Radiographic Testing (RT), Ultrasonic Testing (UT), Magnetic Particle Testing (MT), and Dye Penetrant Testing (PT). Finally, a certified hydrostatic pressure test is executed to validate structural integrity before delivery.
14. Which specific UAE industries do your filtration and separation vessels serve?
Our heavy-duty process equipment is deployed across critical infrastructure and commercial sectors throughout the UAE, including Oil & Gas processing facilities, downstream petrochemical refineries, marine ballast treatment, desalination/water processing plants, and food manufacturing lines.
