Fabrication and Erection of discharge duct of Fume Fan B and Dryer Fan B with SS material in NP plant FACT CD, during ATA 2020.

Pre fabrication of discharge ducts of Fume fan B and Dryer Fan B with SS material before ATA 2020. Work Involves: The required SS materials for the fabrication of new discharge duct of Fume fan B and Dryer Fan B shall be transported from CD stores to work site. The measurements for the fabrication of discharge ducts shall be taken from site / existing one. The new discharge duct of Fume fan B [Duct from fan discharge expansion bellow to the connecting flange to stack B] & Dryer Fan B shall be fabricated with all its inlet / outlet / required connecting flanges etc., as per the same dimensions, sizes and shapes of existing one, for proper / convenient erection. [The plate thickness of duct shall be 06 mm to 10 mm.]. Fixed / loose flange arrangements shall be fabricated with SS plates for all flanged connections. Required SS pad plates / SS supports / SS stiffeners shall be provided / welded to all connecting flanges, manholes, etc. The SS plate cutting shall be done with plasma / cutting wheel only. (Arc cutting will not be permitted ). Full weld all joints with proper fillet as per Arc welding procedure. Inside / outside edges of the cut plate shall be ground properly with suitable bevel / single Vee, where the welding is to be done. The welding of joints shall be done with full-penetration fillet weld and the root-pass shall be DP tested. (Total weight of the Ducts= 06 MT [Approx.]).

Replacement of rubber lined discharge duct of Fume fan B and Dryer Fan B with SS material, during the ATA 2020 period. Work involves: The required scaffolding, tools, tackles etc. shall be arranged at site, for the replacement of discharge duct of Fume fan B & Dryer Fan B during ATA 2020. Rubber lining shall be removed from the area (removal of rubber lining is in the scope of contactor), where the cutting is to be done. The old rubber lined duct shall be removed and transported to scrap yard after cutting the same into number of pieces for easy handling. Temporary supports shall be provided, if required. The newly pre fabricated discharge duct of Fume fan B & Dryer Fan B shall be transported to site and erect the same in position with proper / strong base support. The alignment, level, verticality etc. shall be corrected perfectly. All the flange joints shall be tightened properly and service the duct without any leak.(Total weight of the Ducts= 09 MT [Approx.]).
