Anti-corrosion seamless steel pipe is a kind of steel pipe that has been applied in all walks of life. In the normal use process, the stability of anti-corrosion steel pipe should also be improved.
The first is the requirement for storing the environment around the seamless steel pipe. The selected place should be able to drain smoothly, and also ensure that the environment is clean and there should be no harmful gases or dust in the air.
The second is to ensure that the upper block is under the storage when storing. Also ensure that there is some ventilation. There is also a metal product that is more susceptible to corrosion and must be carefully preserved.
For some large steels, it can be placed in the open air. However, whether it is stored in the warehouse or in the open air, there is no such thing as acid, alkali, salt and cement that is harmful to the steel. For different varieties, it has to be classified and stored.
1. 3pe anti-corrosion steel pipe cutting treatment problem
After the 3pe anti-corrosion steel pipe is straightened, the initial inspection of the soot is carried out to determinethe length of the cutting head and the tail. The purpose of cutting 3pe anti-corrosion steel pipe is to remove the endwith crack, knot, smash, tear and uneven wall thickness to obtain the required fixed length 3pe anti-corrosion steel pipe, and to remove the defects that are difficult to save after inspection, such as Folding, internal crusting, and severe wall thickness are not uniform. Generally, the cutting of the former is performed on the line, while the latter is cut off offline.
2. Control of holding time of 3pe anticorrosive steel tube during heat treatment
The heat preservation time of the 3pe anti-corrosion steel pipe should ensure that the steel pipe in the furnace can becompletely burned, the temperature is uniform, and the desired tissue transformation is completed, thereby obtaining uniform structure and performance.
Generally, the heating temperature can be increased to shorten the holding time.
When performing low temperature annealing (including softening, stress relieving and recrystallization annealing), theannealing temperature is closer to the lower critical point A1, and the faster the recovery of the 3pe anticorrosivesteel pipe, the more complete the effect of eliminating work hardening, therefore, the holding time can also beappropriate shorten.
