Method for identification of steel tubes

Common steel pipe mainly has two forms of seamless steel pipe @https://www.hu-steel.com/product85.html and welded steel pipe. @https://www.hu-steel.com/product90.html.In the process of engineering construction, appropriate steel pipes will be selected according to the specific construction situation, and the cost will be the primary factor.

Seamless steel pipe is mainly a solid tube billet or steel ingot for perforation, made of wool tube, and through hot rolling, cold rolling, cold drawing and other processing, and then formed seamless steel pipe. Since seamless steel tubes contain a members section, this hollow section can be used as a conduit for transporting fluids.

A Welded steel pipe is generally a steel strip or steel plate under the action of external force, make it into a round or square, and then weld the surface joints, thus forming a welded steel pipe. The commonly used processes are arc welding, high or low frequency, cold rolling and so on, but the use of these processes for welding will lead to welded steel pipes. At present, according to the shape of welding seam can be divided into straight seam and spiral welded steel pipe, but the two use different technology. The spiral steel pipe is welded by submerged arc welding, which has the advantages of high welding efficiency and less dust. For high frequency or low frequency welding, mainly based on the principle of electromagnetic induction, due to the ac charge in the conductor will occur adjacent and turbine heat effect, can achieve the welding edge of steel to melt state, the final completion of welding.
In appearance, the difference between seamless steel pipe and welded steel pipe is that the inner wall of the welded pipe has welding ribs, while seamless steel pipe does not. Seamless pipe pressure is higher, welded pipe is generally about 10 MPa. Seamless steel tube is formed once in rolling. Welded steel pipes need to be rolled and welded, generally spiral welding and direct welding. Performance seamless tube is better. Of course, the price is higher.
