Operation steps of pipe opening under pressure

The pipe opening with pressure is a kind of high-tech specialized technology, which is used to process round holes on the running pipe by mechanical cutting. It is mainly used in petroleum, chemical, pipeline and other industries. When the pipeline installation branch, the pipeline pressure perforating technology, which does not affect the normal transportation pipeline, and can ensure the safe, efficient, complete the connection work of old and new pipeline of environmental protection, the operation steps are as follows:

1, with the pressure hole machine, plug in the power, open the motor switch, check the equipment operation, confirm the normal operation, shutdown.

V - 2 fighters, the tapping machine on the base of the pipeline, and then adjust the length of the chain, and bolt positioning and fastening nut, the other end of the chain, make the machine firmly positioned in the pipeline.

3, according to the provisions of the pressure to confirm the opening diameter, fitted with appropriate pressure opener.

4, the motor, again confirm the pressure opening machine, with the pressure opener is running normally.

5, pull (down) with the pressure opening machine handle, so that with the pressure opener slowly down, close to the pipe, to see if the pressure opening hole position is correct; on the contrary, should be closed and re adjust the position after the boot.
