The scope of work for 2.3.1 is as follows, but is not limited to these items: – Detailed design of the factory-made linings for the radiation chamber and the flue above it. -Supply and installation of all refractory materials for the radiation chamber and the flue at the top of the radiation chamber. -Supply and welding of the furnace lining support anchors (the anchor pins are welded by the winning bidder at the furnace manufacturer’s site). -Supply and installation of refractory mortar to accompany refractory bricks (if any). -Protection of refractory materials during manufacturing, transportation, and storage. -Supply and application of coatings resistant to low-temperature dew point corrosion. -Packaging and transportation of refractory materials. -Furnace drying technical services. 2.3.2 The scope of supply is as follows: The supplier shall supply the radiation chambers and the flue gas duct linings at the top of the radiation chambers for 7 types of heaters, namely the disproportionation heater, the isomerization heater, the reboiler of the stripping tower, and the reboiler of the A8 redistillation tower, all of which must meet the requirements specified in the technical agreement and design drawings. The anchorages are welded by the furnace manufacturer; after the furnace is assembled on-site, the supplier arrives at the site to install the lining (including coating against low-temperature dew point corrosion). The lining must meet all the parameters and performance requirements specified in the design documents and this request for quotation. The basic contents of the scope of supply are as follows, but are not limited to these: ceramic fiber modules for the flue at the top of the radiation chamber, the furnace roof, and the vertical walls of the radiation chamber, along with the corresponding anchor bolts ； Clay insulating refractory bricks at the furnace bottom, nano-porous plates, ceramic fiber boards, high-strength low-conductivity castables ； Installation filler material between the collecting duct box lining material, the burner, and the furnace bottom lining ； Coating against low-temperature dew point corrosion. 2.4 Planned duration: Planned duration: 141 calendar days ； Planned start date: December 10, 2020 ； Planned delivery date: April 30, 2021 ； Key milestones: On November 25, 2020, the F-5001, F7001A/B insulation nails along with their layout diagrams arrived at the furnace prefabrication plant; welding of the insulation nails was completed by December 20, 2020. On December 20, 2020, the F-8001 insulation nails along with their layout diagrams arrived at the furnace prefabrication plant, and the welding of these insulation nails was completed by January 30, 2021. On November 30, 2020, the F-6001A/B/C insulation nails along with their layout diagrams arrived at the furnace prefabrication plant, and the welding of these insulation nails was completed by January 15, 2021. The on-site construction period for the lining of a single heating furnace is 30 calendar days. The specific start date shall be subject to the notice from the employer. 2.5 For specific details, please refer to the tender document numbered 1953GDIC-Q001.
