In the case of the production of used welded pipe machine, it is necessary to know the production process regulations of each equipment in order to operate the used welded pipe machine according to the production process regulations.

The sixth step we first understand the water pressure testing process of  used welded pipe machine 

1. Before starting the machine, check whether each system of the hydraulic press is operating normally, and report any abnormality to the relevant leaders immediately.

2. Set the "manual, automatic" switch on the operation panel to the manual position, and the system enters the manual state. In manual operation, you must wait for the head to advance to the position before pressurizing the seal ring.

3. After the high-pressure water in the steel pipe is released, the sealing ring will be under pressure to prevent the sealing ring from being damaged.

4. When the equipment has an emergency failure, the equipment should be shut down immediately to eliminate the failure.

5. Set the "manual, automatic" switch on the panel to the automatic setting, and the system will enter the automatic working state.

6. During automatic operation, the flushing time, pressure holding time and required pressure value can be adjusted at any time according to the situation.

7. When an emergency fault occurs during automatic operation, the switch is turned to the stop position, and after the fault is removed, the operating state is returned to the initial position by manual operation.

After learning the water pressure testing process, we can carry out the actual operation principle of the steel pipe of used welded pipe machine according to the water pressure testing process.
