A seamless tube is a tube that does not have any welding seam. 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. Whereas the seamless pipe does not have any such joint and thus has uniform structure & strength all over the pipe body. So seamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe. Generally the welding seam of the welded steel pipe is the weak point, the quality affect overall performance.Thus seamless pipeis widely used in high pressure equipment, and thermal, boiler industries, corrosive atmosphere and widely use in oil and gas refinery, Petrochemical, Chemical, Fertilizer, Power, Automotive, Bearing, Mechanical & Structural applications.
