ELECTRO RESISTANCE WELDED (ERW)
ERW introduction
Man Industries manufactures HFW (ERW) High Frequency welded pies of various sizes in conformance with various specifications to meet the growing global demand of pipe line. The Company set up a new unit for manufacturing ERW steel pipes and tubes are available in various qualities, diameter, and length and wall thickness of the finished pipes. These pipes use the high frequency induction welding process to manufacture pipe ranging in nominal diameter from 4” to 18” and in wall thickness.
ERW Pipes are manufactured in diameter ranging from 4” NB to 18” NB in strict conformance to API & client specifications from various sectors such as oil, gas, fertilizers and water supply. All the Line Pipe Manufacturing facilities of Man Industries process valid licences to use API Monogram and also possess various customized approvals from reputed clients worldwide.
Electro Resistance Welded (ERW)
- ERW Plant is installed with latest and Advanced Technological features with Automation.
- Entry section is designed to handle 32 Ton coil weight and accumulator is also installed that enables the mill to run continuously while making the coil Joint.
- Strip Ultrasonic for 100 % coverage with 10 % overlap followed by Strip Edge Milling is to get precise strip width and better quality edges for welding
- The FFX Forming and latest technology enables the Quality supply of pipes. The facilities employee the state of the art “FFX Roll Forming” with Automation and High Frequency (1000 KW) Welding with Induction OR contact Method.
- On Line Weld Bead monitoring System for continuous feedback to operator for Internal Bead Scarfing and intermediate Quality checks also installed just after High Frequency Welding.
- 02 x 600 KW Online Seam Normalizer to re-establish the Mechanical properties of Weld seam equal those of base metal.
- Finishing Facilities Supported with End Facing, Hydro Tester, Off Line Ultrasonic Welding, Magnetic Particle Inspection, Weighing and Visual Inspection to deliver highly quality Pipes to customer. The Facilities supported by efficient plant layout, trained & highly skilled experienced man power.
