Steel pipes and tubes can be used for many purposes such as steel pipes for frames and shafts, steel pipes for bicycle frames, steel pipes for furnitures, cdw pipes for shockers, steel pipes for various structural purposes, steel pipes for various engineering purposes etc. We have a very wide range of steel pipes and tubes products. The lengths of the steel pipes & tubes range from 4m to 6.5m unless otherwise specified by the customers. We manufacture steel pipes and tubes in various shapes and size such as square, round, rectangular, triangular, and elliptical or any special shape.

Used for scaffolding and fencing applications, our Hot Dip Galvanized Pipes are especially fabricated with the help of Electric Resistance Welding process. We are amongst the chief Manufacturers, Exporters, and Suppliers of the long lasting Hot Dip Galvanized Pipes, thus offer these at competitive prices. Description Tubes are made from edge trimmed mild steel strips that are slitted from hot rolled low carbon steel coil and conforms to IS: 10748-1995. These edge trimmed strips are formed mechanically into required circular shape and high frequency electricity, i.e., 4,50,000 cycles/second is then used to fuse the pipe together to form a weld joint thus become homogeneous part of the completed tube. The tubes then passes through the sizing section where dimensional tolerance if any are corrected, where after they are cut to length and ends beveled before hydrostatic testing. Thereafter they are sent for protective surface finishing operation such as Hot Dipped Galvanizing or Varnishing as per the specific requirements. The tubes are offered beveled, plain ended or threaded with screwed & socketed. Size Ranging From 15mm NB to 300mm NB with installed capacity (as per international standard BS/EN/ASTM A53 SCH 40) of 2,40,000 MT per annum (UL Approved pipes) Thickness Range From 2.00mm to 10.00mm Applications Automotive PurposesIdlers / ConveyorsStructural PurposesElectric PolesScaffoldsWater, Gas & Sewage pipesWater wells (casing pipes)Air, Steam, Oil & Gas transmission Manufacturing Process Step � 1 Purchasing Raw Material (Steel/Skelp) 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 KWStep � 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
