Sameless pipe
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. Whereas the seamless pipe does not have any such joint and thus has uniform structure & strength all over the pipe body.
Some commonly used models are
Api5L Seamless Pipe ,A53 Gr.B Seamless Pipe,Astm A106 Gr.B Seamless and so on.Advantage
The seamless pipe can withstand higher pressure, higher temperature, higher mechanical stress & corrosive atmosphere and find wide applications in Oil & Gas.
Applications
Applications in petrochemical, chemical, chemical, chemical fertilizers, electric power, automobiles, bearings, machinery and structures.
