Why To Buy From Tirupati Steel


Steel Seamless Pipes

Seamless pipe as the name suggests is a pipe without a seam or a weld-joint in contrast to Seam or Welded pipe. In a Seam or Welded pipe, the seam or the weld-joint is the weaker part of the pipe limiting the strength of the pipe to the strength of the weld-joint. Since the commissioning of its 1st seamless pipe mill in 1992 Tirupati Steel has always been a market leader in India. In the subsequent years Tirupati Steel added another two seamless mills to increase its volume and range. Even today Tirupati Steel continues to maintain its leadership position as the largest manufacturers of seamless pipes in India with 3 mills and a total capacity of 5,50,000 M.Tons per year. Tirupati Steel is also the only manufacturer in India to offer the maximum size range upto 20” catering to customers across all sectors.
