| 7 | Cleaning of exposed steel structure surface back and front plate ofweir side gate no 16 sticking material including loose and foreign material by sand blasting with coarse sand followed by and including cleaning with oil free air blast as per direction of Engineer in charge. With following precaution during/after the sand blasting –4.2.1 Blast Cleaning Surfaces requiring blast cleaning should be sand/ grit/shot blasted after fabrication prior to painting. Heavy deposits of grease or oil may be removed by the solvent like clean mineral, spirits, xylol or white, gasoline, etc. prior to sand blasting. Small quantities of grease or~oil may be removed by the blasting process in which case, however, the abrasive should not be reused if it contains sufftcient oil or grease to render it unsuitabie for blast cleaning purposes. The average surface roughness after sand-blasting should not exceed 40 microns. Blast cleaning should be performed with sand/ grit/shot as per requirements given.in IS 1477 (Part 1) : 1971. After-blast cleaning, thesurfaceshouldbe cieatied from loose dust.and debris preferably by air blast with the help of blower. For the purpose of surface preparation, blast cleaning is classified into four classes as given in 4.2.1.1 to 4.2.1.4. 4.2.1.1 Class ‘A’ This is the best quality of Blast cleaning. Whole surface of steel should be cleaned to bare metal without any res’idual~in any form. 4.2.1.2 Class ‘B’ , : ,. _, Under this class at least 95 percent of surface of steel should be cleaned to bare metal except some tightly bonded residue in the form of millscale/rust only. The extent of residue should not be more than 10 percent of any single square having an area of 6.25 cm’. 4.2.1.3 Class ‘C’ Under this. class at least 80 percent of surface of steel should be cleaned to bare metal except some tightly bonded residue in the form of millscale/rust only. The extent of residue should not be more than 40 percent of any single square having an area of 6.25 cm2. 4.2.6.4 Class ‘II’ Under this class at least 65 percent of surface of steel should be cleaned to bare metal except some tightly bonded residue in the form of millscale/rust only. The extentof residue should not be more than 60 percent of any single square having an area of 6.25 cm2. |
