What factors affect the quality of finished carbon steel reducing pipe

Carbon steel reducing pipe after forming, welding, cooling through a series of processing, but also need to be sawn. In this link, the length of the process ruler directly affects the quality and sale of the finished carbon steel reducing pipe, so the length of the ruler should be controlled between ±5 mm. Not only that, in actual operation, the operator must also strictly follow the following procedures to operate

The operation steps of carbon steel reducing pipe

First of all, power is supplied to the control cabinet, and then each active switch in the control cabinet is closed, and the power switch of the operating station is closed together, and the microcomputer is started.

Next, the unloading start button should be closed, the internal and external control buttons of the service power cabinet should be turned to the external orientation, and the direction adjustment buttons should be moved to the directional orientation.

Then press the step power start button and saw motor start button to start the operation. At this time, the microcomputer display screen appears the operation menu prompt on the sawing of carbon steel reducing pipe, and the operator can perform manual, imitation, initiative and setting according to it.

Before the equipment is operated, it should be checked and acknowledged that the compressed air pressure is maintained at 0.6Mpa, and the manual button should be used to check whether the saw and brake cylinders can move.

Before operation, use manual things to back the flying saw car to zero switch, and the car takes the initiative to change. After the head of the carbon steel reducing tube exceeds the measuring roller, it can be operated by closing the pressing button of the measuring roller and pulse coding.

If the demand makes it keep active operation, then the start key on the small keyboard should be pressed, and the flying saw machine is active and repeated operation.

Then press the stop button, stop the operation procedure, will make the flying saw car sawing carbon steel reducing pipe finished, and then come back to zero before moving, if you want to convert things, press the reset key of the small keyboard, even if the microcomputer display screen appears the main menu, and the key to select things and change the setting parameters.

Carbon steel reducer quality training

In order to ensure the welding quality of the pipe, the welder should be trained and tested to be qualified. Welders to weld the steel pipe, in addition to the basic theory, to figure out the operation skills, the welding process of the pipe may include several positions of downward welding, vertical welding and upward welding (the pipe can not be turned).

The size of the selection of the current should take care of the forming of vertical welding and upward welding (some pipes are not very large, a forming, can not adjust the current halfway), the process of controlling the stability and forming of the arc, can swing properly, and the formation and necessary swing should be combined.
