Customer Questions
Steam Drum Solutions
The steam drum is the heart of a water-tube boiler. It stores the steam-water mixture, separates steam from water and distributes water to riser and downcomer systems. Below are the key questions our customers care about most.
What design scope can ORL supply for steam drums?
We design and fabricate steam drums for low, medium and high-pressure boilers, including utility boilers, industrial boilers, biomass boilers and HRSG / waste heat boilers.
- • New boiler steam drums
- • Replacement drums for existing units
- • Horizontal or vertical arrangement
- • Matching downcomer / riser / header interfaces
Which materials are used for steam drum shells?
Material selection is based on your design pressure, temperature and corrosion requirements. We use certified boiler and pressure vessel steels from approved mills.
- Carbon steel plates such as SA-516 Gr.70 or equivalent
- Alloy steels such as SA-387 Gr.11 / Gr.22 / Gr.91 or equivalent
- Matching Chinese GB grades available on request
- Material traceability with mill certificates
How do you arrange delivery time for steam drums?
The production schedule depends on shell size, internal layout, inspection scope and project workload. After we receive your drawings and technical requirements, our commercial team will confirm a realistic delivery time according to your project schedule or outage window.
- • Engineering review before confirming schedule
- • Coordination with your site installation plan
- • Progress updates during fabrication
What inspections and documentation can you provide?
Each steam drum is delivered with a complete documentation package and can be witnessed by third-party inspection agencies according to your project requirements.
- • Material certificates and welding procedure records
- • Hydrostatic pressure test reports
- • RT / UT / PT / MT non-destructive testing records (as specified)
- • Dimensional and visual inspection reports
How do you ensure steam separation performance?
Internal devices are designed to provide stable water level and high steam purity according to your boiler design.
- Steam separators, cyclones and chevron plates
- Feedwater distribution and baffle systems
- Internal layout matched with boiler circulation design
Can steam drums be customized for my project?
Yes. We support both "build to print" and "engineering support" modes. You can send us drawings, or share design data and let our engineers assist with proposals.
- • Custom nozzle quantity, size and orientation
- • Special internals and support structures
- • Corrosion-resistant overlay or cladding on request

Frequently Asked Questions
Steam Drum FAQ
Common questions about steam drum design, manufacturing and delivery from our customers worldwide.
What information do you need to quote a steam drum?
To provide an accurate quotation, we typically need the following information:
- • Boiler type and application (power plant, industrial, HRSG, etc.)
- • Design pressure and temperature
- • Steam capacity or boiler size
- • Design code requirements (ASME, GB, EN, etc.)
- • General arrangement drawings (if available)
- • Special material or inspection requirements
If you have existing drawings or specifications, those are very helpful. If not, our engineering team can work with your basic boiler data to develop a proposal.
