ERW CEW tubes&
Strength of Bhushan Precision Tubes
Precision welded tubes are manufactured by the High Frequency Induction Welding Process which is commonly known as ERW process. 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.

ERW Tube Manufacturing Process
During entire tube processing change occurs in the steel structure & to remove the metallurgical difference between the weld zone & body of the tube effects of cold working caused in the forming & welding process, the tubes are subjected to heat treatment (normalizing). Normalizing process restore the grain structure thereby relieving the stresses It is essential where controlled mechanical properties are desired. The Normalizing process is carried out in a Bright Roller Hearth Furnace at temperature ranging between 750 ~900 degree.
The tubes are then straightened on 10 rolls straightening machine & tested (weld quality, mechanical properties , Eddy Current Testing, Hydro test – as per spec. requirement) oiled and packed as per customer requirement.

By Cold Drawing process we can make any non standard size for specific end use with close tolerances, better surface finish & superior close mechanical properties. 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 0.40 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.

Spectro Analysis
Bhushan steel use the finest quality steel for tube products which confirm the National & International standards. Bhushan Khopoli plant is fully equipped with an advanced and integrated Quality System to produce strips & tubes as per standards.
The Central Boiler Board has also recognized the Bhushan Khopoli, Tube Division as a “Well Known Tube & Pipe maker” under Regulation 4C (2) of the IBR Act 1950. Bhushan Tubes has also been awarded the ISO 9001/2008, IS:14001:2004 & OHSAS 18001:2007.
The Quality control systems is backed by Modern Laboratory and a test facility for Physical , Chemical & Metallurgical tests.
Tests Carried Out :-
The tubes are packed loose as well as in bundles in round, Hexagonal & square shape as per customer requirement.
