Laying, jointing (by way of circumfrential butt welded joints by electrical arc welding) and testing of Galvanized mild steel tubes (G.I. pipe) of following dia meters confirming to IS1239-2001(latest with upto date amendments) having wall thickness as specified below with bevelled/plain ends in a random length of 4 to 7 meters, including manufacturing reducers/tapers, all short pieces, bends etc. as per site requirements made from parent tubes. The laying of pipe will include all operation such as cutting, welding and jointing, fabrication of bends, tees, etc. including lowering and laying in excavated trenches to ensure required level including flushing, cleaning and hydraulic testing complete in all respects to the satisfaction of the Engineer in charge. The fabricated bends shall have three or four cuts having its radius not less than five times the dia of pipe. The damaged portion of the pipes and specials made from the parent tube during welding or otherwise shall be provided anticorrisive treatment by applying two coats of anticorrosive bituminous paints over a priming coat as per AWWA specifications C-203-1978. The welding electrods shall be as per IS 814 of Advani Oerlikon/L&T or ISI marked make. The rates also includes entire carriage of material, flushing, cleaning & hydraulic testing complete to the best satisfation & direction of Engineer in charge with in all leads and lifts(Earth work in trenches will be measured and paid for separately)
