The present invention relates to a seamless steel pipe Manufacturer installation and more particularly to a seamless steel pipe manufacturing installation comprising a highly efficient line arrangement in which a rolling line and a finishingline are matched in capacity with each other and are operated as a continuous process line .It is well known in the art that in the manufacture of seamless steel pipes by hot rolling, the pipes produced by the rolling line including piercing, rolling and sizing mills are divided into as-rolled pipes requiring no heat treatment and thoseto be heat-treated which require a special heat treatment.

More specifically, the as-rolled steel pipe Manufacturer are transferred from the rolling line to a cooling equipment such as a cooling bed and the pipes to be heat-treated are transferred to a heat treating lineincluding a heating furnace, quenching unit, reheating furnace, etc.With the above-described line arrangement, not only a kick-out mechanism is required for each line but also a vast installation space is naturally required and the equipment layout also becomes complicated. For instance, in the manufacture ofoil well pipes requiring mass handling, if the pipes to be heat-treated must be subjected to such a conditioning processing such as threading of the pipe ends after the heat treatment as in the case of the as-rolled pipes, it is necessary to transfereither the pipes to be heat-treated or the as-rolled pipes to a finishing equipment for thread cutting or the like if the line arrangement is such that the as-rolled pipes and the pipes to be heat-treated are transferred to the following processingequipment by way of separate lines as in the previously mentioned case.

Even if the pipes are transferred to the finishing equipment, if the finishing equipment is in operation, the efficiency will be deteriorated by a delay due to the waiting time andthe number of lines of the finishing equipment must be increased to increase the efficiency, thus making the entire arrangement extremely irrational and uneconomical. manufacturing seamless steel pipe of the present invention relates to installation and more particularly, relates to a seamless steel pipe Manufacturer apparatus, which comprises an efficient line in which the rolling line, and finishingline arrangements each other's capacity to match, and as a continuous process line operation.This is known in the art, arising in the manufacture of a seamless steel pipe by hot rolling production line, comprises a perforated pipe, rolling, and sizing rolling mill is divided into the cold tube without heat treatment and thoseto is heated to deal with this need a special heat treatment.
