Banking on our in-depth experience and knowledge in industry, we are indulged in offering superior quality Pipes (Round & Section). These are manufactured with the use of superlative quality steel at par with the set industry quality guidelines under the direction of domain experts. They are utilized in mechanical and manufacturing industries, shipbuilding, bridging, steel structure, automobile chassis, etc. Available in numerous dimensions, these Pipes (Round & Section) can be availed from us at market competitive rates in secured packaging.
Other Information :
The basic raw material for manufacturing of pipes is HR Coils. After receiving the raw material in Coil shape these are slitted into various widths according to requirements of Pipe Dia at Slitting machine. After slitting the slitted coil is loaded on the uncoiler and stored in accumulator to enable the continuous running of the mill while tail end of slit is welded with the leading end of next coil with the help of MIG welding.
The strip is passed through a set of rolls to get the shape and the outer edges of strip are heated by high frequency induction coil. Outside flash of welding is removed with the help of round tool(Scarfing tool)so as to give better finish. The welded tube is again passed through a set of rolls to get the specified tolerances on outside Diameter. Inside flash of weld can also be removed if required by the customer above 75mm outside Diameter. Our product Range is from 10.00mm NB to 200mm NB. After the pipes are made these are cut into the Required lengths with Programming Logistic Controls (PLC). After cutting the pipes the pipes are sent together to Deburring machine for removal of burr at the end to avoid any injury to the workmen.
After removal of Burr each pipe is Hydraulically tested to check the leakage in the pipe. Various tests according to specifications are carried out at the shop floor itself.
Galvanizing & Threading:
After hydraulic testing of pipes at 51kg/cm2 or as per customer requirement, the pipes are sent for galvanizing process to avoid the rusting on the surface if required by the customer. The pipes are dipped in Hydro Chloric acid to remove the rust from the surface. After cleaning the surface the pipe is washed in running water. After washing the pipe is dipped in flux solution to maintain adherent property of zinc on pipe. The pipes are dipped in a molten zinc Bath at a temperature of 450oC to get the proper adherent Coating.
After Galvanizing the pipes are sent for threading wherever it is required. The threading is done on the highly sophisticated machines to have the best threading to avoid any leakage on threads while laying in the use. After threading each pipe is marked with the series paint as required by BIS and bundled for dispatch.
