Buy Hot Finished Seamless Mechanical Tube in Wide Range of Sizes & Thickness

Hot Finished Seamless Mechanical Tube is used mostly in structural applications. The standard tubes and pipes are made with typical specifications where the mechanical tubes are formed to especially focus on the yield strength requirements. The Mechanical Seamless Tube is made from different types of materials. There is a range of materials that are available for the making of these mechanical tubes. These are often produced under the ASTM A513 and ASTM A519 standard specifications. The dimensions of the tubes vary. There are tubes from 4mm in outer diameter to 1219.2mm for larger pipes. The yield strength for specific diameter and wall thickness is the most looked at factor in Hot Finished Seamless Mechanical Tube.

The hot finished, cold drawn tubes can be made in different shapes such as square, rectangular or round shapes. There are also custom shapes. Mechanical tubes have to have the ability to withstand forging and forming operations because they are usually machined, forged and formed in the application, especially during the installation. The Cold Drawn Seamless Tubing has good surface smoothness and can be used for a few applications that require precise dimensions from the tubes. The cold drawn seamless tubes, also known as the cds tubing is used for its uniform tolerances. The cold rolled products are more enhanced and have increased strength compared to the hot rolled products.
