DHB Boiler, a specialized manufacturer dedicated to the production of power plant and industrial boilers, is pleased to announce the successful renewal of its A-Level Pressure-Bearing Special Equipment (Boiler) Manufacturing License. Following a comprehensive review, the license validity has been extended to January 2030, further validating DHB’s position as a reliable manufacturing base for the energy industry.

Rigorous Audit and Manufacturing Standards
The renewal process, concluded on November 24, involved a meticulous series of evaluations, including preliminary preparation, license application, internal self-inspection, and an intense on-site audit. The review was conducted by a distinguished expert group from the China Special Equipment Inspection and Research Institute (CSEI).
Adhering strictly to the TSG07-2019 Regulation on Production and Filling Licensing of Special Equipment, the expert group utilized a multi-faceted approach to verify DHB Boiler’s manufacturing strength. This included listening to management reports, on-site workshop inspections, document verification, and technical interviews.
The experts confirmed that DHB Boiler’s quality assurance system operates efficiently, our resource allocation is robust, and our fabrication capabilities meet high industry standards. The successful renewal signifies that DHB fully complies with the stringent requirements for A-Level boiler manufacturing.
