Seamless Tubes are derived from solid steel that is in sheet or bar form and is formed into a solid round shape known as “billets” which are then heated and cast over a form such as a piercing rod to create a hollow tube or shell. These kinds of Tubes are known for their ability to withstand pressure more efficiently in comparison to other methods of pipe manufacturing processes, as well as being fast and cost-effective. Seamless Tubes are generally used in gas lines, as well as tubes that carry liquids

Seamless Pipe Making :
Seamless tubular products are made by one of two hot forging process, rotary piercing and rolling, or extruding. seamless tubing is different than steel bar – because of the hole – there are many similarities to the extent that seamless tubing is frequently referred to as “hollow bar”.
|Tubes according to ASTM A312|
For small diameter or thin walls or both, where many drawing passes are required, a Carbon maximum of 0.040% is necessary in grades TP 304L and TP 316L. Small outside diameter Pipe are defined as those less than 0.50 in. [12.7 mm] in outside diameter and light wall pipe as those less than 0.049 in. [1.20 mm] in average wall thickness (0.044 in. [1.10 mm] in minimum wall thickness).
