OHSAS - 18001 certified Khopoli Adminstrative Building ERW & CEW tubes ERW Tube Process Precision welded tubes are manufactured by the High Frequency Induction Welding Process which is commonly known as ERW process.

5 After slitting the small slits/coil in desired sizes, slit coils are transferred to STEEL Tubes Manufacturing Mills. Coils are loaded on Pay off Reel and passed through looping cage then to series of forming rolls which bend the strip in tubular form with abutting edges. The abutting edges are then heated to the required Welding Temperature by means of High Frequency Induction The externally & internally Flash removed with the help of Scarfing Tools, then welded pipe passes through coolant tank and cooled. The pipe passes through sizing section where the outer dia is maintained & pipe straightened with the help of Turk Head. The required length is cut on cut off carriage on line without stopping the mill. The cut length pipe is rolled out on conveyor & stopped by stopper at end of Conveyor and ejected to the pipe collecting pockets.

9 In CEW process the welded tubes (ERW Tubes) are used as parent hollow. After Normalizing & Surface Treatment (Conventional &. Oil route) the tubing is cold drawn through a Die and over a Mandrel to reduce diameter & wall thickness to required dimension. BHUSHAN has an Oil Draw facility to produce extremely smooth ID finish with close tube tolerance for Cylinder bore tubes where piston moves freely repeated under severe conditions. The tooling & process is well designed to achieve close ID tolerances with ID finish Ra max. Such close tolerances & finish enable customer to use oil draw tube directly without additional operations. BHUSHAN is also manufacturing TFF tubes (Telescopic Front Fork) tubes as per customer specification, which is high tensile tubes (UTS - 88. kgmm2 min) with close dimensional tolerance.
