Detail

In contrast, the failure rate of the sizing machine is the lowest, and it is easier to deal with. The common production accidents of the used welded pipe equipments sizing machine are as follows: ① Scratches. ②Drilling pipe. ③The tube is not round.

 

In order to let everyone understand the common faults of used welded pipe equipments sizing machines, we analyze the common faults of used welded pipe equipments sizing machines — drill pipes.

Drill pipe

Drill pipe problems are rare, and generally occur more often when thin-walled pipes are produced. This is mainly because the rigidity of thin-walled pipes is poor, and the thin-walled pipes are easily bitten by the rollers. Therefore, the following problems in production will cause drill pipe accidents.

 

(1) Bearing damage. After the bearing of the lower flat roll is damaged, under the pressure of the upper flat roll, the rolling line height of the pipe will drop, and the pipe will easily drill into the lower roll edge of the vertical roll pass. If the vertical roller bearing is damaged, the gap between the upper and lower roller edges will increase, and the pipe will also drill into the gap at any time.

(2) The center of the hole pattern is not correct. Whether it is a flat roller or a vertical roller, when the center of the hole pattern is not correct, it will lead to the phenomenon of drilling pipe. When the vertical roller is out of alignment, under its misdirection, the pipe will be drilled into the gap of the roll edge of the flat roller. Improper timing of the flat roll will also cause the pipe to drill into the gap in the roll edge of the flat roll. This drilling phenomenon generally does not occur in the production of thick-walled pipes unless the center of the hole pattern is too far off. Drill pipe is more likely to occur only when producing thin-walled pipes with small diameters.

 

If the used welded pipe equipments has common failures of the sizing machine, the drill pipe should pay attention to these two aspects (1) bearing damage. (2) The center of the hole pattern is not correct. Hope to be of some help to you. Our company has many brands and wide resources, there is always one suitable for you.
