MS Pipe bends of suitable angle as per site conditions from the available 200mm dia MS pipe of 1.5m overall average length with a wider curve, providing & fitting with MS Flanges 200 mm dia of standard thickness at two ends, which are properly circumferentially welded with ISI marked M.S welding electrodes, weld should free of spurts and gaps & all the slag was removed by chipping. The job also includes complete painting by way of removing the rust/dirt from the outer surface of the pipe by sanding away with emery/sand papers/steel wire brush, cleaning and making the surface even for painting then apply one coat of primer and two coats of paint on all exposed parts. P/F of 200mm dia MS pipe 13 m approximately for 2 no. suctions lines of unit I and II, by way of preparing the ends with the flanges of appropriate size to be coupled with bends. The job also involves cutting of the MS pipes as per site requirements by gas cutter. Aligning the suction lines with tools and tackles using skilled labour. Strengthening and support of MS suction pipe by installation of hooks/ clamps on either side of the MS pipe by grouting MS angles (50x50x6 mm) after excavation of pits of size(1’x1’x1.5’) and fixing with cement concrete mixture along the length of each suction pipe at 8 spots. after curing for 5 days welding the angles and suction pipe for extra strength/support to suction pipes. M.S Flanges to have suitable drilled holes to match the joining pieces & faced for perfect fit. The job included cost of welding electrodes, Oxy-acetylene gas equipment, tools & tackles required for the job, hire and carriage charges to and fro, cost of material, Cost of use of Lathe facilities for flanges, beveling of pipes by hand grinders at site wherever required etc. & labour charges for skilled & semi-skilled labour, transportation and handling charges all to be borne by the tenderer.

Providing, Fitting and installation of 2 Nos. 250 mm dia foot valves for pumping unit no. I and II by way of welding 2 No. flanges as per foot valves sample/size to 2 No. 200 dia MS suction pipe piece (provided in item no 1) and installing both foot valves on each MS suction pipe end by p/f of appropriate no. of nuts, bolts and rubber gaskets as per size. Job further involves lowering of the foot valves along with suction piece by using chain pulley block and skilled labour, joining of the bends and the suction pipes by bolting via flanges with appropriate no. of new nuts and bolts.
