Dismantling of the 500 mm dia Dressor Coupling of unit no. 1, 3, 4&7 at workshop by way of separating all components such all types of tie rods, nuts, and bolts. Repairs, reconditioning, updating of the components by providing / fixing of new tie rods, nuts, re-strengthening of the coupling by welding / fixing of additional patches. Also P / F of nitrile rubber extruded profiled seal for ensuring leak proof operation of the assembly. Assembling, fitting at workshop/at site. Complete job of restoration including cost of material , painting, carriage charges and labour charges involved job also includes the hire charges of special tools required during the operation of the job etc.

Strengthening of the 500 mm dia Sluice valves at workshop by way of dismantling and separating all components such as spindle rod, spindle nut & gate flap C.I gland etc and then restoration, reconditioning, updating of the worn out components. Also reconditioning of flap and housing seat of valve and then finishing to required size for complete leak proof system and smooth functioning of upward and downward movement of the gate flap. Also strengthening, servicing of hand wheel, gear system. Assembling, fitting and checking operation at workshop. Complete job of repairs including cost of material required, labour charges,carriage charges at workshop.( unit no. 1,2 & 4 )

Fabrication/Repairs / re-strengthening of the structural supports of the discharge pipelines by way of gas cutting / extraction of old rusted & damaged MS angle supports, anchoring fasteners & base plates, Fabrication at site of MS 50 x 50 mm angle supports ( 4 nos vertical 2ft long each, 4 nos horizontal 5ft long each & 2 nos cross members 6 ft long each,) MS Flat 50mm x 8mm of semi circle shaped both end flat and drilled with of hole size16mm dia. On the top of the 500mm dia each discharge pipeline 02nos. and MS 50 x 50 mm angle supports of semi circled shaped under the bottom of the 500mm dia. each discharge pipelines 02nos. Both the ends are welded with vertical supports and drilled with hole of 16mmdia. under each Dressor coupling clamping the pipe line with nut & bolt (with proper alignment of the pipe joint) by gas cutting to sizes, welding of sections with each other precisely so as to minimise the vibrations & to avoid misalignment of the Dressor coupling during operation of the pump. Also patch welding of MS sheet 8 mm thick on the 500m pipeline at the different leaking areas after preparation of the surface by sanding with emery paper & filling the holes initially with filler material. Welding work is to be carried out in double layer using good quality welding electrodes. Complete job at site of installation involving charges for material required including its carriage, hiring of heavy tools & tackles, gas cutting set, welding equipment & labour charges etc.
