Seamless tube is tubing that has no weld seam as it is produced from a solid round billet. The billet is produced to a required chemistry in either steel making process and is heated and then pierced and rolled or spun to produce a shell or mother tube. The mother tube is then worked by further hot finishing and cold finishing processes to produce the desired shape, dimensions, and properties. It is also tested to assure proper that the final material meets the required specifications. Inherent in this product is the capability to provide thicker walls than other tube, and with higher strengths and a more uniform structure.
Seamless tubing for mechanical and light structural applications is one of the most commonly used seamless steel tube varieties.
Seamless Mechanical tubing application:
Seamless mechanical tube is produced to meet specific end use requirements, specifications, tolerances and chemistries. This allows for more specific property uniformity throughout the tube compared to standard pipe or tube. While Mechanical tube can be produced to standard specifications when requested, it is often produced to “typical” properties that focus mainly on the yield strength for a precise size and wall thickness. In some applications with severe forming, yield strength may not even be specified and the mechanical tube is produced to be “fit for use”. Mechanical tubing encompasses a wide range of both structural and non-structural applications.
The use of steel pipes to manufacture ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing rings, jack sets, etc., which have been widely used in steel pipes. Steel pipe is also an indispensable material for various conventional weapons, and steel pipes are required for the manufacture of gun barrels and barrels.
Seamless Mechanical tubing type:
Seamless Mechanical tubing is manufactured to typical mechanical tube properties in accordance with ASTM A513 and
ASTM A519 specifications. Some of the most common types of mechanical tubing are Drawn Over Mandrel tubing (DOM), Hot Rolled/Finished Seamless tubing (HRS), Cold Drawn Seamless tubing (CDS), Hot Rolled or Cold Rolled Electric Weld tubing (HREW/CREW), and 4140 Alloy tubing. Mechanical tubing is not limited to these specifications and can be produced to exact customer requirements when appropriate. Mechanical products are ordered to a specific outside dimension (OD) and “gauge” or wall thickness or by outside dimension (OD) and inside dimension (ID). Additionally, most mechanical tubing can be available in galvanized as well upon request.
