Seamless steel pipes are always used to transfer oil , gas ,water etc liquid object.For seamless steel pipes,the greatest advantage is its increased ability to withstand higher pressure than welded pipes.Welded steel pipes are weaker because of welded seam.With this advantage,seamless steel pipes have equally strong around entire circumference. Seamless steel pipes are nominally manufactured in sizes NPS 1 through NPS 26.Because larger dimension seamless steel pipes are more difficult and expensive to produce, and Continually, seamless pipes used to have better surface finishes, especially in smaller sizes.
