On June 15th, the water pressure test of boiler 9 in the Rabota project in Indonesia was successful, and boiler 9 officially entered the insulation stage of the furnace body. On the same day, the steel inner cylinder of Project 9 was successfully lifted into place, and the construction of the chimney inner cylinder was successfully completed.
Before the hydrostatic test, the project department conducted a detailed inspection and verification of the test conditions, completion of inspection items, and defect closure with the owner, supervisor, etc. to ensure the success of the hydrostatic test in one attempt. The chimney of the project consists of two parts: a concrete outer cylinder and a steel inner cylinder. The concrete outer cylinder is 144 meters high, the starting elevation of the base is 30.35 meters, and the diameter of the steel inner cylinder is 5.3 meters. It is constructed from the base at 30.35 meters to 150 meters, with a total height of 119.65 meters. A single steel inner cylinder weighs 116.3 tons. Three 220 ton hydraulic jacks are arranged on the 135 meter bearing platform for overall lifting. The 9th steel inner cylinder that was lifted into position this time is also the last inner cylinder among the 3 steel inner cylinders. Through the joint efforts of all parties, the construction of the 9th steel inner cylinder has been successfully completed.
