      Abstract: Developments of steel pipe market and present state of tube billet and seamless tube production in foreign countries are described. The world, steel pipe market does not show a good situation but the the horizontal continuous casting technology for tube billets has been successfully developed. The seamless steel pipe production technology now has stepped to a new level through incorporating new type piercing mills into all kinds of rolling mills and developing shell wall thickness inspection under high temperature and multl-destructive inspection technology.
