ERW Tube Manufacturing Process
ERW Tube Process
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 a 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.
Testing and Quality Control
The Quality control systems is backed by Modern Laboratory and a test facility for Physical , Chemical & Metallurgical tests.
- Tests Carried Out :-
- Spectro Analysis
- Eddy Current Test
- Tensile Test
- Hydrostatic Test
- Impact Test
- Micro - examination
- Weld Strength (Flaring, Flattening, Crushing, Reverse Flattening, Flanging & Bend)
Packing
The tubes are packed loose as well as in bundles in round, Hexagonal & square shape as per customer requirement.
- Loose
- Master Bundle with polythene
- Bundled with HDPE bagged at ends
- Bundles wrapped with polythene (HDPE )
