ASCO CARBON STEEL PIPES ASCO Steel Tubular products are manufactured by either seamless or welding processes. Those processes are further divided into several processes. In the Plug mill process, a Solid round (billet) is also used. It is uniformly heated in the rotary hearth heating furnace and then pierced by a Mannesmann piercer. The period billet or hollow shell is roll-reduced in outside diameter and wall thickness. The rolled tube is simultaneously burnished inside and outside by a reeling machine. The reeled tube is then sized by sizing mill to the specified dimensions. From this step the tube goes through the straightener. This process completes the hot working of the tube. The Tube (referred to as a mother tube) after finishing and inspection, a becomes a finished product.
