With pressure opening operation procedures: the gate valve to the maximum caliber. The feed hand wheel clockwise, center drill (drill) top to the main line, half of the week (to prevent reverse handwheel knife). Start the motor, turn the handwheel slowly and then feed it. After the drill is drilled through the pipe wall, cut off the power supply. After cutting off the power supply, manual feeding can be done, indicating that the drill has been drilled.
Bore clockwise idle handwheel feed, when the bucket knife top to the wall after the reversal of half of the week (to prevent breakage). Start the motor again and rotate the handwheel clockwise to feed it. Feel the bucket knife, cut off the pipe wall, cut off the power supply. After cutting off the power supply, hand feed, if the handwheel does not move, that cutting is not completed, to reverse the half week handwheel, restart the motor, and then continue to slow feed. When the motor cuts off the power supply, the handwheel can rotate feed, indicating that the cutting of the hole has been completed.
The open hole with pressure is carried out in the completely enclosed cavity, and the cutting process of the cutting tool is isolated from the air without the possibility of fire and explosion and no pollution to the environment. The device is an open hole contact without stopping production, and is suitable for any medium other than oxygen and various pipes of different diameters.
A pressure opening is a method of making an interface between a pipe and a vessel. When opening, the pipe and vessel are under pressure or in use. Increase the branch pipeline, for input or output material set temperature probe monitoring points for equipment (plugging equipment) provides connection with pressure hole is completely enclosed within the cavity in the cutting process with air separation, no possibility of fire and explosion, no pollution to the environment. The device is an open hole contact without stopping production, and is suitable for any medium other than oxygen and various pipes of different diameters. Bore pipe solves the problems of online maintenance shutdown. Buck. Release. Use of fire and other traditional practices. To avoid operational risks. To improve safety. The maintenance is fast and reliable. For many years the domestic economy of city gas network. The oil and petrochemical pipeline owners to provide high-quality equipment and services.
