PILGERING

• Cold Pilgering process using full link die and tapper mandral
• To reduce the cross section  by upto 90% because the process relies on large number of small forming steps
• Cold Pilgering and are longitudinal cold rolling process that reduce the diameter and wall thickness of metal tube in one process step
• By cold Pilgering process surface finish achieved matter than cold drawing finish (Less than 0.4 micron) and improved microstructure grain size.
• Our pilgering range are OD12 to 73mm and wall thickness 0.8 to 4mm

COLD DRAWING

• In cold drawing process raw material tubes are coated with some special chemical or applied some special lubricant oil.
• The tubes are pulled through tungsten carbide die and flotting/fixed plug inside the tubes, resulting in reduced tube diameter and wall thickness corresponding increases in tube length
• Our capacity of drawing are OD 6 to 609.6mm & thickness are 0.8 to 12mm.
