Gelan Process Vessels & Industrial
Tanks: ASME-Certified, Custom
Engineered for Harsh Environments

Gelan engineers and manufactures high-performance ASME pressure vessels and industrial process
tanks built for demanding petrochemical, chemical, and refining applications. From high-pressure
reactors to large-scale distillation columns, every unit is fabricated to handle complex media,
fluctuating pressure cycles, and extreme temperatures.

 

As a premier pressure vessel manufacturer, we combine advanced metallurgy (Carbon, Stainless,
Duplex, Clad), precision welding, and rigorous NDE testing to ensure long-term reliability. We hold
ASME 'U' & 'S' Stamps and comply with global standards including PED (EU) and EAC (Russia/CIS),
making us a trusted partner for global EPCs.

 
 

Explore Gelan Process Vessels & Industrial Tanks

Custom Pressure Vessels (High & Low Pressure)

  • Heavy Wall Fabrication: Capability to roll and weld plates up to [insert thickness, e.g., 100mm+] for high-pressure vessel applications.
  • Material Versatility: Expertise in fabricating solid stainless steel, duplex, and explosion-bonded clad vessels for corrosion resistance.
  • Code Compliance: Designed strictly per ASME Section VIII Div. 1 & 2 guidelines for safety and durability.

Reactor Pressure Vessel

  • Critical Process Control: Equipped with internal coils, half-pipe jackets, or dimple jackets for precise temperature regulation during chemical reactions.
  • Agitator Integration: Reinforced nozzles and top-heads designed to support heavy-duty mixers and agitators.
  • Severe Service: Engineered for high-temperature hydrogenation, polymerization, and catalytic processes.

Distillation Columns & Towers

  • Full-Length Fabrication: Manufacturing capability for extra-long columns (up to [insert length, e.g., 50m]) shipped in one piece or flanged sections.
  • Internal Installation: Pre-installation of trays, packings, distributors, and demisters to reduce on-site assembly time.
  • Wind & Seismic Design: Structural calculation ensures stability against wind loads and earthquakes for tall vertical towers.

Industrial Storage Tanks

  • API & ASME Standards: Designed per API 650 for atmospheric storage or ASME VIII for pressurized storage (LPG, Ammonia, etc.).
  • Large Capacity: Site-erected or shop-fabricated stainless steel tanks and carbon steel tanks available for bulk liquid storage.
  • Custom Features: Available with internal heating coils, insulation, ladders, and platforms.

Overcoming Challenges in Industrial Vessel & Tank Fabrication

Comparison Item Gelan Solution Industry Challenge
Corrosion Resistance Weld Overlay (strip cladding) and explosion bonded plates provide high corrosion resistance at a fraction of the cost of solid alloy Process media containing chlorides, acids, or H₂S rapidly degrade carbon steel and can cause Stress Corrosion Cracking (SCC)
Thermal & Pressure Cycling Precision fabrication with certified welding procedures and engineering-led stress analysis Frequent thermal shock and pressure fluctuations demand full penetration welding and accurate stress control
Code & Certification Compliance 100% certified welders with in-house hydrotest, RT, UT, and full code documentation Incomplete documentation or failed RT/UT tests can stop projects; global jobs require ASME, PED, or DOSH/MOM compliance
Structural & Mechanical Design Engineering-driven design using PV Elite and ANSYS to verify stresses before fabrication Nozzle loads and wind/seismic forces are often underestimated, increasing operational risk
Oversized Equipment Delivery Integrated global logistics with skid mounting and sea-worthy export packaging Large vessels are difficult to transport and risk damage during international shipping

FAQs About ASME Pressure Vessels & Process Tanks

1. What is the difference between ASME Section VIII Div 1 and Div 2 vessels?

Div 1 is the most common code for standard pressure vessels. Div 2 is an alternative rule that allows for thinner wall thickness (saving material cost) but requires more rigorous stress analysis and NDE testing. Gelan can manufacture to both standards within the ASME Boiler and Pressure Vessel Code.

 

We offer both. We can fabricate based on your existing drawings, or our engineering team can perform the mechanical design (wall thickness calculation, nozzle load check) based on your process data using PV Elite software.

Carbon Steel, 304/316 Stainless Steel, Duplex, Inconel, and custom clad plates depending on temperature and corrosion requirements.

Yes—horizontal, vertical, jacketed, baffle-integrated, insulated, or skid-mounted options are all available.

Standard pressure vessel testing includes Hydrotest, RT/UT/PT/MT, weld map verification, PMI, dimensional inspection, and full QA documentation.

Yes. We design and manufacture trays, packings, mesh pads, distributors, and vane-type demisters.

For equipment that exceeds standard container sizes, we use Flat Racks or Break Bulk shipping. We design custom steel saddles and skid mounts to ensure the vessel is not damaged during ocean transit.
