ASME Section VIII Design
ASME U Stamp
API 650 / API 620 Tank Standards
Custom pressure vessels, process tanks, columns, separators, reactor vessels, and storage tanks for refinery, gas processing, petrochemical, chemical, and hydrogen production projects.
Gelan supports engineering review, code-based fabrication, inspection documentation, and delivery coordination for EPC teams and project owners.

Gas-Liquid and Three-Phase Separation
Custom separator vessels and drums for gas-liquid separation, oil-water-gas separation, knockout service, flash separation, surge control, and process buffering.
Best for refinery, gas processing, petrochemical, and chemical units where stable phase separation and downstream protection are required.
High-Pressure Reaction Service
Custom reactor pressure vessels for hydrogenation, hydroprocessing, catalytic reaction, polymerization, gas-solid reaction, and other high-pressure or high-temperature process conditions.
Best for CDU, VDU, fractionation, solvent recovery, chemical separation, and other process systems that require stable mass transfer.
Vapor-Liquid Separation and Fractionation
Industrial columns and towers for distillation, fractionation, stripping, absorption, and vapor-liquid separation in refinery and petrochemical process units.
Best for CDU, VDU, fractionation, solvent recovery, chemical separation, and other process systems that require stable mass transfer.
Industrial Storage and Process Holding
Custom storage tanks and process tanks for crude oil, chemicals, fuel, water, intermediate products, and other industrial media under atmospheric, low-pressure, or project-specific conditions.
Best for refinery tank farms, petrochemical storage areas, chemical plants, utility systems, and process units that need safe media storage or buffering.
Built around real operating and design conditions, not reused templates.
Wrong pressure or temperature basis can lead to undersizing, overdesign, and late engineering changes.
We review design pressure, design temperature, medium, process duty, nozzle load, wall thickness, and safety margin before fabrication.
Helps reduce design risk, control fabrication cost, and support smoother review for EPC teams and project owners.
Selected for corrosion, temperature, pressure, and long-term service life.
Wrong material selection can cause corrosion, cracking, short service life, higher maintenance cost, or unplanned shutdowns.
Gelan supports carbon steel, stainless steel, duplex stainless steel, clad plate, and project-specified materials based on your medium, temperature, corrosion risk, and code requirement.
Helps improve corrosion resistance, operating reliability, and equipment life under demanding process conditions.
Controlled fabrication from material cutting to final inspection.
Poor welding control or weak fabrication records can delay EPC review, third-party inspection, and owner acceptance.
Gelan supports ASME-oriented pressure vessel and tank fabrication with controlled welding procedures, qualified welders, forming, assembly, heat treatment, and inspection hold points.
Helps meet project code requirements, improve fabrication quality, and reduce acceptance risk before delivery.
A vessel is not only a shell. It must support the real process function.
If internals, nozzles, and flow paths do not match the process duty, the vessel may meet dimensions but fail to support stable operation.
Gelan designs and fabricates vessel details based on separation, reaction, fractionation, buffering, or storage service, including nozzles, supports, trays, packing, baffles, mist eliminators, and other functional parts.
Better process fit and more stable equipment performance.
Complete documents help move the project from fabrication to site handover.
Incomplete records can delay shipment release, EPC review, site installation, and final owner acceptance.
Gelan supports material certificates, welding records, NDT reports, hydrotest records, dimensional inspection, nameplate information, packing records, and data book preparation.
Helps make project review, delivery, installation, and final handover smoother for EPC teams and project owners.
Built for real projects, not just equipment supply.
Works from process duty, drawings, specifications, and project standards.
Supports vessels, tanks, columns, reactors, heat exchangers, fired heaters, and modular packages.Defined checks help keep manufacturing quality stable.
Supports overseas project communication, export packing, documentation, and shipment coordination.
Supports standalone equipment, equipment packages, and modular systems.
Only focuses on making the equipment shell.
Only handles simple vessels or tanks.
Mostly familiar with domestic delivery only.
Only delivers one product without considering the wider process unit.
Watch short videos from Gelan’s workshop, including fabrication, welding, inspection, and delivery. See how custom pressure vessels and process tanks are built for real industrial projects.

Useful information includes:
If your drawings are not complete, Gelan can still review early requirements for custom pressure vessels, process tanks, or pressure containers.
Share your drawings, operating conditions, material requirements, and project standards. Gelan will help review your custom pressure vessel, process tank, or storage tank requirement and provide project-based manufacturing support.
