Human factors are the focus of gas galvanized pipe welding control. Due to the lack of necessary post-weld control methods, it is easy to cut corners and affect the quality; at the same time, the welding particularity of galvanized pipes makes it difficult to ensure the welding quality.

In terms of appearance, the difference between seamless steel pipe and welded steel pipe is that the inner wall of welded pipe has welding ribs, while seamless pipe has no welding ribs.

Spiral steel pipes are single-sided welded and double-sided welded. Welded pipes should ensure that the water pressure test, tensile strength of the weld and cold bending performance meet the requirements.

Why does the small-diameter thick-walled seamless steel pipe have transverse cracks? During the use of the small-diameter thick-walled seamless steel pipe, the surface sometimes encounters the phenomenon of transverse cracks. There are many reasons for this. The scope of application of the small-diameter thick-walled seamless steel pipe is as follows. If the deformation of the small-diameter thick-walled seamless steel pipe is relatively small in the case of air drawing, the inner and outer surfaces of the seamless steel pipe will cause additional stress fields caused by internal pulling.

Now let us introduce the American standard seamless pipe, which is a kind of seamless steel pipe. Seamless steel pipe is another kind of steel pipe. Now let us introduce the classification of hard pipe.
