Seamless steel pipes are now used in a wide range of fields, such as in construction, transportation, etc. The reason why seamless steel pipes can be used so much is that they have their own strengths and advantages. Compared with the general steel pipes used in the past, seamless steel pipes adopt a series of high-tech manufacturing technologies, and then the seamless steel pipes have excellent quality.
Everyone is familiar with welded pipes. Today, I will introduce to you what is the difference between seamless steel pipe and welded pipe?
First of all: the most important thing is that their molding processes are different. Ordinary steel pipes, such as water pipes, are generally welded by bending flat materials. This process is relatively simple and rough, and a weld can be found on the finished product after processing. However, seamless steel pipes are generally formed by squeezing molten steel through an annular slit and then undergoing processing processes such as stretching. Under this process, there is no weld.
In terms of performance, seamless steel pipes have greatly improved pressure bearing capacity compared to ordinary steel pipes, so they are often used in high-pressure equipment. Such as pipeline connection of hydraulic equipment, etc. The welding seam of ordinary steel pipe is its weak link, and the quality of the welding seam is also the main factor affecting its overall performance.
