METHOD STATEMENT
-
Programming Section - Auto cad Drawing is downloaded & programmed in Vulcan software.
-
Raw material input port: GI Coils will be loaded in the starter line decoiler using forklift
-
Machine data from the programming section will be downloaded/ feeded in to the touch screen controller of starter line.
-
Straight duct with notching for seam and flanges are produced from starter line. also sheets for vulcun bed are sheared using starter line
-
Male & Female pittsburgh Seam is produced after notching by pittsburg lock machine.
-
TDC flanges are formed with flange making machine on either side of the sheet
-
The output sheet after Seam and flange formation is lead in to the wrap breaker for bending
-
Seam closing is done on the pittsburgh lock seem closer
-
The corners are placed and crimped for the TDF ducts
-
Duct mate flange frame as per the duct sizes are produced using bench cutter
-
Duct mate frames are fixed to duct by riveting.
-
Transverse joint piece profiles are cut by vulcan machine. Job sheets are downloaded / feeded to vulcan computer to cut the profiles for fittings like elbow, offset etc.
-
Stiffener beading is formed on by the beader for the fitting pieces
-
Male & Female pittsburgh Seam is produced after notching by pittsburg cornomatic machine
-
S & C cleats for ducts without flanges are produced in lion cleat bender
-
MS & S.S Ducts longitudinal joints & angle flange fixing are doing by typical welding procedures.
-
S & C Clips are formed on roll former machine and send along with the ducts for installation.
-
QC Checking and verification carried out before dispatch.
-
Typical loading of duct in vehicle
-
Assembly of ducts @ site
-
Leakage testing at the site.
