Shanghai Tengxi Builds a Blast Relief Wall for Dongfeng Commercial Vehicle's Test Chamber, Fully Upgrading Safety Defenses!

• Customer Introduction

Dongfeng Commercial Vehicle Co., Ltd. is headquartered in Shiyan, Hubei, the "Capital of Commercial Vehicles in China", and is the core division of Dongfeng Group for medium- and heavy-duty commercial vehicles. The company has an R&D center and oversees several specialized factories and subsidiaries, with Shiyan as its base and operations covering many regions. Its main businesses include medium- and heavy-duty complete vehicles, key assemblies (cab, chassis, engine, transmission, axle), casting and forging, and the aftermarket.

• Blast Relief Protection, Safeguarding Vehicle R&D

With the booming development of the automotive industry, vehicle R&D has long surpassed simple mechanical assembly and become a frontier that integrates cutting-edge technology and complex experiments. From new energy battery performance testing to engine extreme-condition simulations, every experiment carries potential explosion risks. As a core facility for ensuring R&D safety, the blast relief wall plays an irreplaceable role in this challenging field with its unique design and functionality.

Recently, Dongfeng Commercial Vehicle Co., Ltd. completed the detailed design work related to the blast relief wall as part of the test chamber renovation and equipment installation project. At the frontline of commercial vehicle R&D, safety protection is a critical area that allows no complacency. Shanghai Tengxi, leveraging professional expertise and craftsmanship, deeply participated and worked with all parties to strengthen the safety defenses of this important test base.

• Project Push, Safety Upgrade

Wuhan Dongfeng Commercial Vehicle initiated a renovation and equipment installation project for the test chamber located at No. 653 Zhushanhu Avenue, Wuhan Economic and Technological Development Zone, to comprehensively raise test chamber safety standards and meet strict national regulations. Construction of the blast relief wall became a top priority.

The designed area of the blast relief wall far exceeds national standard requirements, demonstrating an extreme commitment to safety. The project ensures rapid pressure release in the event of an unexpected explosion by installing core components such as blast relief wall panels, blast relief screws, and tensioning cables, providing all-round protection for personnel and equipment.

• Strict Compliance, Meticulous Construction

The project strictly followed the national standard "Blast-resistant and Explosion-relief Doors and Windows and Roof and Wall Building Structures" 14J938. From design to construction, all stages were controlled to high standards to ensure the reliability and professionalism of the blast relief wall engineering. During construction, not only was precise positioning and installation of the blast relief screws and tensioning cables required, but strict safety measures such as fall protection for work at height and temporary electrical management were also enforced, achieving coordinated progress in safety, quality, and environmental protection.

• Conclusion

The implementation of this project will significantly improve the safety level of the test chamber, providing a more reliable environment for Dongfeng Commercial Vehicle's R&D and testing work. Shanghai Tengxi applies professionalism and care to perfect every detail, allowing R&D personnel to explore automotive technology with greater peace of mind. In the future, Shanghai Tengxi will continue to rely on rigorous professionalism and high-quality standards—from raw material selection and precision manufacturing to strict testing—to provide customers with a full lifecycle service system covering design, construction, and maintenance.
