• Slitting : Prime HR Coils are first slit into predetermined width as per the sizes & thickness of the pipes
• Forming : The slit coils are passed through a set of Pinch , Levelling rolls & forming rolls.
• Welding : The formed tubes are than welded through a continuous process of High Frequency Welding using Electric Resistance Welding Technique. The excess weld material is removed with a stationed tool in the running process.
• Sizing : Before cutting of pipes in fixed lengths with COC Cutter the pipes are passed through a set of Sizing rolls to maintain dimensional accuracy of pipes as per the standard specifications.
• End facing : It is a process of chamfering the ends of the pipes to make it square cut and smooth before galvanising.
• Hydro testing : The pipes are then tested hydraulically at the specified test pressure maintained for a time as specified by the relevant standard.
• Galvanizing : The galvanizing process is used to galvanize pipes/hollow sections with zinc through the hot dip galvanizing process which increases the life of the pipes/tubes and prevents them from rusting.
• Threading : The black/galvanized steel pipes are threaded and socketed as per the requirement of the specified standards.
• Packing : The threaded/Plain ended pipes are then packed in bundles as per standard specifications.
