Qualified bidders are welcome to come and bid. The specific arrangements are as follows: 1. Procurement Plan Name: Harbin Pharmaceutical Group Pharmaceutical General Factory Mingshui 601 Workshop Phase I Project Flange Replacement and Minor Maintenance Installation Engineering Services Public Bidding Content: 1. Project Name: Harbin Pharmaceutical Group Pharmaceutical General Factory Flange replacement and sporadic maintenance and installation works for Phase I project of Mingshui 601 workshop. 2. Project location: Workshop 601 of the cephalosporin raw material project, located at No. 3 HaHei Road in the factory area of Harbin Pharmaceutical Group Sanjing Mingshui Pharmaceutical Co., Ltd. 3. Construction scope: Synthesis, recycling, and sterile areas in workshop 601. 3.1 Removal of non compliant flanges and electrostatic connections within the area; 3.2 Installation of non compliant flanges and electrostatic connections within the area; 3.3 Removal and installation of pipelines related to the installation and removal of flange obstacles; Water pressure and air pressure leakage testing of construction pipelines. 3.4304 stainless steel storage tank repair. 3.5316 material equipment and pipeline argon arc welding repair. 3.6 Outdoor carbon steel pipe piping, specification DN100, length 100 meters, pipeline insulation, installation of electric heat tracing belt and power supply and control box: (This item does not require construction due to environmental factors, and list numbers 11-15 do not require quotation). 3.7 Production and installation of steel stairs for the air conditioning mezzanine on the second and a half floors of the sterile area. 3.8 Recycling area 304 stainless steel material 25m3 horizontal distillation kettle replacement head, welding liquid level gauge port, reflux pipe mouth, insulation repair. 4. Construction scale: 589 DN50 flanges need to be replaced and installed, of which 61 are located above 5 meters; Replace 720 DN25 flanges, of which 119 are located above 5 meters; The replacement of the flat welding flange is required to first prefabricate the welded pipe section in accordance with the specifications and usage requirements, minimizing the length of the prefabricated short pipe to 10cm, and then welding the original pipeline after cutting the flange. The replacement of flanges at high altitudes requires confirmation from both parties that they are non compliant flanges before implementation, and significant markings should be made for later leak testing; The electrostatic connection is stable and reliable, and the installation bolt holes are located for easy viewing from below. 4.2 It is necessary to remove the DN50 stainless steel pipeline that poses an obstacle to the replacement of the flange for 50 meters, and then restore the installation after replacing the flange. 4.3 Pipeline water pressure and air pressure test: DN25 pipeline 200 meters; Repair of DN50 pipeline 800 meters 4.4304 stainless steel storage tanks: 12 units in total, with volume specifications of 2.5m3, 5m3, and 10m3 respectively. 10 tanks need to be repaired and welded with local leakage points on the head, and 2 tanks with a capacity of 2.5m3 need to be welded with steel plates around the weld bead of the head. 4.5 One leakage point of 316 material equipment in the synthesis area and one leakage point of 316 material pipeline in the sterile area need to be repaired by argon arc welding. 4.7 Production and installation of steel stairs on the second and half mezzanine floors of the sterile area, with a running step length of 2 meters and a slow platform length of 1 meter
