With the five essential systems of "operation management system, quality assessment system, sales responsibility system, process assessment system and R& D incentive system" being our foundation, we keep driving our corporate standardization developmentto ensure the operational precision of all departments. Trace-ability The quality assurance system of "integrated six major steps" is exclusively implemented, including material trace-ability system - material recheck system - manual operation records traceable system - process performance system - process specification manual - quality standard manual. When materials are inspected and delivered into respective workshops, an inspection serial number is assigned as per batch number of each boiler; during manufacturing process, materials are delivered according to each inspection serial number; while separating materials, the inspection serial number is shifted onto all sub-items & parts as per stipulated positions. Process cards and inspection records are respectively applied to log the delivery of inspection serial number of process-materials (including welding materials). All product records are input into the product quality files upon completion. All pressure parts are identified by welder-code seal at welding lines to thoroughly ensure the trace-ability of all parts and accessories. Five Major Centers NDT Center, Physical and Chemical Testing Center, Product Inspection Center, Weld Testing Center, Metering & Measurement Center are established to work with the entire production process for eliminating any production error and insufficiency.
