Since the mandrel 100 is seamless,it is inherently stronger than a corresponding mandrel which was cut and spliced while being formed.Thus,the mandrel 100 is reusable many times more than similar mandrels having a seam.Moreover,the represented seamless mandrel 100 is capable of producing more uniform completed fiber wound hollow vessels.

Wherever you look,seamless steel tubes are an integral part of modern life.Today,the oil and gas industry,the construction and mechanical engineering industries,and automotive manufacturers demand ever better tubes made of higher steel grades,with closer tolerances and new dimensions. Advanced mandrel mill technology for premium Mandrel Bars are one of the key pieces of tooling required during the production of Seamless Tubes and Pipes.Once the billet has been pierced,the Mandrel Bar supports the tube shell internally during elongation and wall thickness reduction.A mandrel lubricant for use in the production of seamless tubes.The mandrel lubricant composed of graphite,clay minerals from the smectite class,a
