Detail
If the high frequency welded pipe machine refers to the chemical composition and mechanical properties of welded tube blanks that require certain inspection methods to be known as invisible defects; then, those defects that can be seen only by vision are called tube blanks. Overt defect.
The dominant defects of the welded tube blank of the high frequency welded pipe machine generally include cracked edges, broken edges, sawtooth, pitting, scratches, roll marks, dark spots, edge burrs, sickle bends, wrinkles, waves, edge warping, and points. Layers, warped skins, pinholes, sticky rolls, soft spots, rust, oxide layers, towers, loose rolls, etc. Let me introduce you to the causes of cracked edges and the impact of cracked edge billets on welded pipes.
Alice
The peeling skin refers to the iron sheet on the surface of the tube blank. One end is connected to the tube blank substrate, and the other end is separated from the substrate. The difference between it and delamination is that the local warping is obvious, but the formation mechanism is similar to that of delamination. It belongs to the extreme form of partial delamination, and it is located on the surface and is broken.
The effects of warping on the production of welded pipes are as follows:
(1) It is easy to damage the induction coil or the contact, and the magnetic rod will run out, forcing the machine to stop.
(2) The pressure-bearing capacity of the pipe is reduced.
(3) The sensory organ is not good, and it does not meet the requirements of the surface quality of the welded pipe.
Regarding the effect of the welded pipe blank defect of the high frequency welded pipe machine (9) on the quality of the welded pipe, I hope it can be helpful to you.
