2. Project Overview and Price Comparison Scope
2.1 Project Location: Chongqing Xiangyu Salt & Chemical Co., Ltd.
2.2 Project Scope: The renovation project of the synthetic combined-soda ice machine at Chongqing Xiangyu Salt & Chemical Co., Ltd. involves pressure-tapping and hot tapping on existing pipelines. For this operation, one DN50 opening will be made on the main gas ammonia inlet pipe (DN600) of the combined-soda ice machine. The medium inside the pipeline is gaseous ammonia, with a working pressure of 0.4 MPa and a temperature ranging from 0 to 10°C, located at a height of 2.5 meters. Additionally, one DN50 opening will be made on the main DN250 supply line for the small tank, where the medium is also gaseous ammonia, with a working pressure of 1.4 MPa and a temperature at ambient conditions, situated at a height of 10 meters. To avoid disrupting production, the company has determined that two DN50 PN2.5 gate valves must be used for welding and creating these two openings.
2.3 Construction Period: The specific timing shall be subject to Party A’s production requirements.
2.4 Project Scope: The head-end pressurized hole-opening operation for the synthetic soda ash ice machine renovation project of Chongqing Xiangyu Salt & Chemical Co., Ltd.: This operation involves opening one DN50 hole on the main pipe of the gas ammonia inlet (DN600) of the synthetic soda ash ice machine. The medium inside the pipeline is gaseous ammonia, with a working pressure of 0.4 MPa and a temperature ranging from 0 to 10°C, at an elevation of 2.5 meters. Additionally, one DN50 hole will be opened on the main supply line for ammonia to the small tank (DN250). The medium inside this pipeline is also gaseous ammonia, with a working pressure of 1.4 MPa and a temperature at ambient conditions, at an elevation of 10 meters. To avoid disrupting production, the company has determined that two DN50 PN2.5 gate valves must be used for welding and creating these two holes.
