Powering Vietnam’s Energy Future: Sunwen Industry Wuxi Co., Ltd. Supplies Membrane Water Wall Tube Panels for the Mong Duong Thermal Power Plant
- Vietnam

1. Project Overview
In the rapidly developing Southeast Asian energy market, Vietnam stands as a growing industrial hub with an ever-increasing demand for electricity. Among its key energy initiatives is the Mong Duong Thermal Power Plant, a flagship power generation facility under Vietnam Electricity of Vietnam (EVN), operated by EVNGENCO 3.
This large-scale coal-fired power plant plays a crucial role in meeting the nation’s energy requirements while supporting industrial, commercial, and residential needs.
Sunwen Industry Wuxi Co., Ltd. was selected as a trusted supplier to provide a critical component for the plant’s efficient operation — Membrane Water Wall Tube Panels, custom-manufactured in strict accordance with the client’s provided drawings.
2. Client Information – Vietnam Electricity (EVN)
Founded in 1954, Vietnam Electricity (EVN) is the state-owned corporation responsible for power generation, transmission, and distribution in Vietnam. Through its subsidiary EVNGENCO 3, the corporation operates some of the country’s largest thermal power plants, ensuring stable energy output to meet growing economic demands.
EVN’s long-standing mission is to ensure uninterrupted electricity supply while continuously upgrading and modernizing its power generation infrastructure. The Mong Duong Thermal Power Plant is a prime example of this commitment, designed to operate with high efficiency and reliability.
3. About the Mong Duong Thermal Power Plant
The Mong Duong Thermal Power Plant is located in Quang Ninh Province, Vietnam. As one of the largest coal-fired plants in the region, it has a substantial capacity, contributing significantly to Vietnam’s national grid.
The plant’s design incorporates modern thermal power technology, enabling it to operate efficiently under demanding conditions. To maintain such performance, every component — especially those in direct contact with high-temperature steam and combustion processes — must be manufactured to exacting standards.
The Membrane Water Wall Tube Panels supplied by Sunwen Industry Wuxi Co., Ltd. are an integral part of the plant’s boiler system. They function to absorb radiant heat from the combustion chamber, convert water into steam, and ensure stable pressure and temperature control within the boiler.
4. Our Role and Supply Scope
Sunwen Industry Wuxi Co., Ltd. was tasked with manufacturing and supplying 126 metric tons of Membrane Water Wall Tube Panels. This assignment required precision fabrication based on detailed technical drawings provided by the client.
Key Supply Details:
– Product: Membrane Water Wall Tube Panel
– Quantity: 126 Metric Tons
– Standard: Manufactured as per the client’s provided drawings
– End User: Vietnam Electricity of Vietnam (EVNGENCO 3)
– Application: Boiler system of Mong Duong Thermal Power Plant
5. Technical Overview – Membrane Water Wall Tube Panels
Membrane Water Wall Tube Panels are critical to the operation of coal-fired boilers. They are arranged along the walls of the combustion chamber, forming a barrier between the heat source and the boiler’s structural components.
Functions:
1. Heat Absorption: Captures radiant heat from the combustion process, maximizing thermal efficiency.
2. Steam Generation: Converts water into high-pressure steam to drive turbines.
3. Structural Protection: Shields boiler walls from high-temperature flame and gases.
4. Improved Efficiency: Reduces heat loss and improves overall plant performance.
Manufacturing Requirements:
– Precision Welding: Tubes and fins welded with high accuracy to ensure leak-proof operation under high pressure.
– Material Quality: Steel grades selected for high temperature and pressure resistance.
– Dimensional Accuracy: 100% compliance with the provided drawings to ensure perfect fit during installation.
– Surface Treatment: Anti-corrosion protection to extend service life.
At Sunwen Industry Wuxi Co., Ltd., each manufacturing stage underwent strict quality control, from incoming material inspection to final dimensional checks.
6. Manufacturing Process at Sunwen Industry Wuxi Co., Ltd.
Our production process for the Mong Duong project followed a structured approach to ensure reliability and consistency:
1. Material Procurement: Certified boiler-grade steel sourced from approved suppliers.
2. Cutting & Shaping: Tubes cut with precision equipment according to drawing specifications.
3. Membrane Welding: Automated welding processes used to attach fins between tubes, forming the membrane wall structure.
4. Dimensional Inspection: Continuous measurements to maintain tolerance compliance.
5. Pressure Testing: Hydrostatic tests conducted to ensure panels withstand operational pressures.
6. Surface Treatment & Packaging: Panels coated with protective layers and securely packaged for export.
7. Project Challenges and Solutions
a) Tight Delivery Schedule
The power plant had a narrow maintenance window, making delivery timing critical.
Solution: Sunwen implemented a multi-shift production plan, enabling on-time completion without quality compromise.
b) Dimensional Precision
Even slight deviations could cause installation delays.
Solution: Intermediate inspections at every stage, with laser-based measurement tools to ensure accuracy.
c) Overseas Transportation
Heavy and large panels required careful export packaging and logistics coordination.
Solution: Collaborated with experienced freight forwarders and used reinforced packaging for transit safety.
