Size Range : From 3� diameter to 10� diameter Conforms To API-5LPSL-1PSL-2 Grades ABX-42X-46X-52 Applications Air, steam, oil & gas transmissionStructural purposesIdlers / conveyorsAutomotive purposesScaffoldsWater wells (casing pipes)Water, gas & sewage pipesElectric polesManufacturing Process Step � 1 Material received from SAIL / ESSAR Steel Ltd. / Lloyds / ISPAT or other any approved vendor. The steel shall be fully conformed to the API 5L / IS Standard Specification or as per Customer�s Specification. Testing/ Checking and Identification of Raw material shall be done as per API 5L / IS Standard Specification.Step � 2 Edge Preparation & Milling Edges of Coil / Skelp are form in edge breaking unit at initial stage so that perfect forming is achieved at welding area. Strip edges are given mill cut on both sides with edge milling machine to make the edges clean and square for perfect butt welding with high frequency. It shall be done before passing the strip to forming process.Step � 3 Forming of Pipe Strip is passed in number of horizontal rolls after edge breaking and form cages supported by vertical rolls to receive an open edge round tube before welding. At the final stage of forming, rolls are provided with guide fins to have a proper proportionate gap and correct entry in welding roll.Step � 4 High Frequency Welding Finally the pipe shape performed after forming process, it passed through welding heads followed by the seam guide. The process of welding is based on ERW process. Electric welding shall be performed with a minimum welder frequency of 200 KHz. The fusion takes place through a roll assembly set for proper welding. Bead trimming shall be done as per API 5L / IS Standard or as per Customer Specification.Step � 5 Seam Normalizing Normalizing is carried out on weld and HAZ after welding at the temperature of 8500 C to 9000 C. The temperature of seam normalizing is monitored by a non contact indicator having the digital display along with recorder. Equipment: Seam Normalizer Capacity : 500 KW.Step � 6 Sizing A set of sizing roll is ahead of cooling zone, water cooled pipe is passed through sizing rolls which control the Ovality and required dimensions, which is finally verified with measuring instruments as specified in relevant Specification.Step � 7 NDT Testing (Eddy Current) Eddy current testing is the process of inducing small electrical currents in an electrically conductive article and observing the resultant reaction between the magnetic fields involved. Equipment: Eddy Current Flaw Detector (PC based).Step � 8 Finishing of the Pipes Finished pipe are cut to required length by cut of carriage. Thereafter both ends of pipes are beveled by the end facer. Finally each pipe are checked for its Outer diameter, Inner Diameter, Thickness, Straightness, and length.Step � 9 Hydro Testing After completing all the above process, all pipes transferred to the hydro testing bench. The test pressure shall be given to the pipes as per relevant specification or as per Customer Requirement.Step � 10 Galvanizing Process Hydro Test passed pipes are send for Hot Dip Galvanizing confirming to various Indian Standard / International Standard.Step � 11 Marking Marking on the pipes shall be paint stenciled as stipulated in API 5L/ IS Standard or as per the customer�s requirement, on each length of the pipe.

We are one of the major producers of hot dip galvanised coils and sheets, corrugated/plain sheets , pre-painted/colour coated coils and sheets and black and galvanised pipes of size ranging from 15 mm nb to 350 mm nb dia.
