ERW Pipe Plant
ERW pipes are extensively used in agriculture industry and construction activities like scaffolding and casing in bore wells. They are used for channeling water, gas, crude oil and chemicals at various pressures and densities over long distances. Considering the challenging and varied applications, the pipes are produced to meet highest national and international standards and specifications.
The pipe plant is equipped with state-of-the-art machines, slitting lines, pipe mills, galvanizing units, finishing machines and failsafe, high pressure hydro testing machines. The plant also has sufficient handling facilities, both EOT and mobile cranes supported by pipe conveyer systems.
Quality assurance begins at the raw material stage and continues across every level of the manufacturing process, till the pipes are packed for dispatch. The quality assurance department is strategically supported by a modern laboratory for various metallurgical and chemical tests, and a test house for testing physical properties. It has been awarded the prestigious ISO 9001:2008 certificate by DET NORSKE VERITAS (DNV) for its quality systems.
Surya group has an installed capacity of 6,00,000 MT per annum to manufacture ERW pipes from OD ½" to 16" according to various national & international specifications including API5L upto Grade X80 PSL2. The group also manufactures Oil Country Tubular Goods (OCTG) as per API 5CT Gr H40, J55, K55 PSL 1 and is a successful supplier to the US markets. Pipes conforming to AS 1074/ AS NZ 1163 and EN 10219 are also manufactured and find ready acceptance from reputed customers. In addition to these, the plant also produces black, red painted, galvanized & pre-grooved pipes.
ERW pipes are made of HR coils. After being longitudinally slitted & edge milled, the strip is progressively formed into a circular shape by passing it through a series of forming rolls.
Continuous welding is carried out by a high frequency induction welding machine, and the seam is formed by fusing the edges without filler metal. The weld bead reinforcement (inside), is removed, if needed. The welded pipes, after cooling, are cut in appropriate length after attaining its roundness and specified outer diameter.
The pipes are conveyed to the finishing bay for finishing, testing and inspection. Hydro testing of pipes is undertaken to detect leaks and fissures prior to galvanizing and threading. Some of these pipes are subsequently galvanized and threaded as per specifications/client requirement.
Water Based Red Painted Pipes
Round pipes from size "1/2" to "6" manufactured as per EN 10255 & 10217-1, AS: 1075 & EN: 10219 are painted with water based Red color paint for applications in fire protection industries, HVAC and mechanical engineering applications.
