ERW Pipe Plant

  1. ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape. In the initial times it was done with the low frequency A.C. current to heat the edges. Now, since 1970 the low frequency process changed to high frequency A.C. current to produce a higher quality weld.
  2. 24 inch dia, 16mm thick ERW pipes are formed by using continuous coil to coil joining. The machine has got 14 sets of VFD’s of various capacities.

Major Applications: Water Pipelines,Agriculture & irrigation (Water mains, industrial water pipe lines, plant piping, deep tube-wells & casing pipes, sewerage piping), Gas pipe lines,LPG and other non-toxic gas lines

Forming Press (JCO)

  1. M.S. Plate of 18mtr length, 4mtr width, 50mm thickness are longitudinally bent and formed into round pipes of maximum diameter of 1.3 mtr.
  2. This forming press consists of 27 Servo valves used for controlling the top sword, bottom balancing beam & various high pressure, high flow hydraulic pumps.
  3. The synchronization of various cylinders in the top & bottom beam are done through PID using high speed processors.

Tack Welding

  1. Tack welding, a necessary preliminary step in many welding projects, must be performed correctly to achieve optimal results from the final weld and to minimize part defects. Quality is as important in tack welding as it is in the final weld.
  2. An advantage of this procedure is that if the alignment for final welding is found to be incorrect, the parts can be disassembled easily, realigned, and tack welded again
  3. Tack welding is real welding, even if the welds are deposited in separate short beads.
  4. It also Temporarily ensures the assembly's mechanical strength against its own weight if hoisted, moved, manipulated, or overturned

PIPE COATING INSIDE & OUTSIDE

  1. The inside & outside pipe coating line was installed basically to provide anticorrosive paint coating on steel pipe.
  2. Again here also process technology was supplied by the M/S EUPEC, Germany.
  3. We had supplied the entire Automation system for blaster & coating line includes AC drives Panels, PLC panels, MMI operations, Software development & commissioning.

Decoiling Line

  1. The Decoiling line is the First of its Kind In The World for Spiral Pipe forming from coils of max 25mm thickness to be decoiled, end & edge champered, & formed into spiral pipe with continuous coil to coil welding. The Winch arrangement stores the coil of length 140meters in the loop & shall feed material without stoppage during feeding of next coil in line.
  2. The system consists of more than 80 AC drives, 4500 I/O PLC, Scada with Fiber optic, profibus & Ethernet communication buses..
  3. The welding stations comprise of the angular & straight rollers driven by asynchronous motors for better accuracy with the AC Inverters on a common DC Bus system.

Plate & Coil Mill

  1. We had done entire finishing line plate conveyor automation & also automation of Pre-Leveler, Hot-Leveler, Cooling Bed, Rocking Share machines.
  2. The above system includes S7 400 Siemens PLC with 15 remote I/O’s, 63 ABB drives & 3 DP/DP Couplers on profibus.
  3. It also includes interfacing between various systems like Saw Cutter & Edge Miller machines from Linsinger, UT machine from GE Inspection.
  4. Finishing line PLC interfaced with main Mill PLC, Down Coiler PLC, Paint Marking system on S7 TCP/IP protocol.

Pipes Conveyor Automation

  1. There were various machines in the process of pipe manufacturing for step by step operations.
  2. All these machines were connected by flat/conical roller conveyors for handling the steel plate/pipe.
  3. We had supplied the total solution for the automation of this conveyor handling system by using 3100 DI/Do PLC system & various field instruments like heavy duty limit switches & long range proximity switches from IFM Germany.
  4. The total length of conveyor rolls automated, was about 2200 meters. There were 3 PLC CPU stations & numerous remote I/O stations operating via Profibus & wireless communication.

EXPANDER

  1. The Mechanical Pipe Expander machine is principally a Hydraulic Mandrel type expansion head operated by a reciprocating cylinder a controlled pressure of 400Bar for various diameters of pipe under expansion.
  2. The entire mechanical equipment was supplied by M/s. MANESSMAN-DEMAG, Germany, pioneer in the field of steel pipe manufacturing.
  3. The max. Capacity of pipe under expansion is 12 meter long, 60 inch dia. & 50mm thick.
  4. This was the third machine of its kind & capacity in the world.
  5. Our roll in the project was panel manufacturing, drawings, software development, site erection & commissioning.

Hydrotester

  1. Pressure testing of pipes for leaks, seams, cracks or imperfections is an important quality process, but can prove to be a tedious job.
  2. Maximum test pressure is 500 bar for the period of 30 seconds.
  3. The process of testing is a time cycle of water filling, air venting out, pressure holding, force balancing through a series of hydraulic servo (water & oil) electro valves.
  4. The testing report is generated on a plain paper chart recorder & as well in a SCADA in the form of a retrievable graph.
