For three Mills requirement of welding at pipe mill – (a) 150 KVA (Induction welder) (b) 150 KVA (Induction welder) (c) 200 KVA (Induction welder) (For this we require 1000 kW power) 4. At the side of tube mill two EOT crane capacity of 7.5 MT & 5.0 MT required. There two crane will be treated for uncoiler to finish products. 5. Two compressors are of 20 kg/cm2/HP will be required to operate the mills pipe. 6. Cooling tower will be installed after C.O.C of pipe mill No. (4) that should be treated urgently. 7. After cutting of pipes each mill should carry end facing machine & hydro testing machine for facing and testing of pipes. 8. Stock of pipes will be kept towards the last pillar before starting of road(Weigh bridge side). That place will be most efficient for stock of pipes upto 800 MT/1000 MT. 9. Raw materials as strip to downloaded upto stock of 300 MT. 10. Our plan is to generate 5000 mt strips of various sizes and to roll in three mill. 11. Balance equipments are in process of order that should be confirm urgently because as per my schedule, mill of 2” will be started upto August 1st week. 12. For this running target all materials should be ordered urgently, some machinery & equipments are ordered but should be followed smoothly like cranes, compressor, end facing & hydro testing machine, cooling tower. 13. Manpower regarding labour is very slow as discussed with Honorable Sanjay Babu & Honarable D K Tiwariji they are doing the needful action. 14. Foundation of 3” mill is expected to ready by this week and foundation of 2 “ mill is expected to start from 17.05.2011 because of excavating soil are to be disturbed big hip of soils to be cleared from the site. 15. Balance all plants & lay out are as per drawing, always I am in touch of M/s – S K Engineers, HiTech, Induction welder Party. Note :- All visual and respective process and flow chart regarding strip and pipe mill will be send within three day.
