First of all: the main is their molding process is different. Ordinary steel pipes, such as water pipes, are usually welded after bending the flat plate. This process is relatively simple and rough, and a weld can be found on the waste products after processing. The seamless steel tube is generally molten molten steel through the ring slit backlog out after the treatment process such as tensile molding, in this process there is no weld.
In terms of performance, seamless steel tube has made great progress in bearing capacity compared with ordinary steel tube, so it is often used in high pressure equipment. Such as hydraulic equipment pipeline connection. The weld position of the common steel pipe is the weak link, and the weld quality is also the main factor affecting its overall performance.
