On November 16, 2009 (local time), the water pressure test, a milestone in the new steam boiler EPC project generally contracted by CHMC, succeeded at the first time.
BANDIRMA Boric Acid Factory was provided a 130T/H circulating fluid bed boiler by CHMC; the steam drum working pressure was 7.6 Mpa ; the steam outlet pressure was 6.4Mpa ; the overpressure test pressure was 11.4 Mpa according to ASME standard.
On November 14, 2009, CHMC site manager organized engineers from construction organizations to inspect the boiler at site and gave the correction suggestions as per the 22 terms in the hydraulic boiler test outline.
On November 15, CHMC site manager organized the design organization, boiler works representatives, construction organization to hold a special subject meeting, checked all the conditions before the water pressure test, classified and perfected the technical materials before the water pressure test (installation document and welding data ) and made a general arrangement.
In the evening of November 15, the team used the desalted water provided by the owner to fill the boiler. In the morning of November 16, 8:30, the first pressure boosting was made. Then the steam drum working pressure reached 7.6Mpa, we made a pressure stabilization observation; all parameters met the specifications within the 30 minutes.
Accompanied by CHMC site manager, plant manager from the owner and plant supervising engineer mounted the boiler for inspection, checked the boiler tubing and the pressure drop in pressure gage; the second test began after all parameters met the requirements. The overpressure test was finished successfully at 15:30p.m.
Firecrackers was lit on the project site to celebrate the victory, and CHMC site manager, boiler technicians from construction organization and owner supervising engineer signed the acceptance certificate in a happy manner.
So the Hydraulic boiler test was succeeded.
The owner showed their thumb to us as he pointed to the boiler valve.
One thing to be pointed out was that all welded joints, valves did not leak and the owner was very satisfied with the equipment and installation quality.
Within 3 months since the civil work started, CHMC project department had finished the underground foundation, steel frame hoisting, steam drum positioning, and other milestone work.
The owner supervising engineer often used “unbelievable” to describe the construction quality and high efficiency of the Chinese. The successful implementation and delivery of this project would facilitate and favor CHMC in expanding a broader market in Turkey.
