Double‑Tubesheet Heat Exchanger & Clean Steam Boiler – Integrated Solution
As a leading double tubesheet heat exchanger clean steam boiler manufacturer, we deliver a compact, high‑efficiency unit that combines the superior heat transfer of a double‑tubesheet exchanger with the reliability of a clean‑steam boiler. Designed for petrochemical plants, refineries, and large‑scale process industries, this integrated system reduces footprint, simplifies piping, and cuts operational costs while meeting stringent emission and safety standards.
Our solution is engineered for continuous duty cycles, delivering stable steam quality even under fluctuating load conditions. With flexible customization options, you can specify tube material, shell size, and steam pressure to match your exact process requirements.
How It Works – Dual‑Function Design
The double tubesheet construction features two concentric tube bundles separated by an intermediate water jacket. Hot process fluid passes through the inner bundle, transferring heat to the outer bundle where clean steam is generated. The intermediate jacket serves as a thermal buffer, ensuring uniform temperature distribution and protecting the tubesheet from thermal stress.
Clean steam is produced in a dedicated boiler chamber that uses the recovered heat from the exchanger. The design eliminates the need for a separate heat recovery steam generator (HRSG), reducing capital expenditure and installation time. Integrated safety valves, pressure sensors, and automatic blow‑down control maintain steam purity and system integrity.

Application Scenarios
The integrated unit excels wherever high‑purity steam is needed alongside intensive heat recovery:
- Refinery desalter and distillation columns – Provides dry steam for stripping while recovering heat from hot crude streams.
- Chemical reactors – Supplies process steam for heating and agitation, reducing separate boiler footprint.
- Petrochemical plant utilities – Supports turbine feed‑water pre‑heating and steam‑driven compressors.
- Power generation auxiliary systems – Enables efficient waste‑heat recovery from exhaust gases.
FAQ
What is the minimum order quantity (MOQ) for a custom‑designed unit?
Our standard catalog models have an MOQ of one unit. For fully custom designs, we typically require a MOQ of two units to optimize tooling and engineering costs, but we are flexible for large‑scale projects.
Can the system be adapted to different steam pressures?
Yes. The double tubesheet heat exchanger clean steam boiler manufacturer offers pressure options from 1.6 MPa up to 6.0 MPa. Adjustments are made by selecting appropriate shell thickness, reinforcement rings, and safety valve settings.
What is the typical lead time for a bespoke configuration?
Standard units ship within 30 days after order confirmation. Custom configurations, including material upgrades and control system integration, are delivered within 45‑60 days, depending on engineering complexity.
Do you provide warranty and after‑sales support?
All units come with a 24‑month warranty covering material and workmanship. We also offer optional extended service contracts, on‑site commissioning, and 24/7 technical hotline support.
