Vulnerability 1: Ordinary iron gates can easily be locked into the house. A thief can carry out an ordinary iron door with four screws to fix the door lock within a minute by simply carrying a long iron.
Loophole 2: Water pipes, gas pipes and other pipes become thieves “laddersâ€. In many residential buildings, rainwater pipes, sewage pipes, gas pipes, etc. are all installed outdoors. Some of them are also close to balconies and windows, facilitating the use of these pipes to climb into the room.
Vulnerability #3: Ventilation windows become a "channel" for thieves. Indoor kitchens and toilets are often located in the dark corners of residential buildings and are not easily seen. Near the sewers, gas pipes, and the ventilation windows of kitchens and toilets, it is easy to become an “entrance†for burglary at night.
Vulnerability four: security network, air-conditioning position is easy to climb into the room "shortcut." Anti-theft network if the installation is not standardized, it can not play the role of anti-theft, especially some residents have not yet replaced the old-fashioned anti-theft network, the thieves often use the anti-theft network as a climbing ladder, climbing up and down to commit crimes, weak prevention measures High-rise tenants are extremely unfavorable. Some occupants did not install air-conditioners in the air-conditioned air-conditioned spaces reserved in the buildings. They ignored the reserved air-conditioners and facilitated the thieves to climb and settle into the house.
Vulnerability 5: Rooftops, garages are easy to hide. The thieves use the roof reins to swing and jump from the top to the bottom of the house to commit crimes. Underground garages and fire prevention passages are also used by thieves.
So how should these anti-theft vulnerabilities be avoided? First of all, the residents themselves must be vigilant and cannot be ignored. To address the above five major security loopholes, you need to do the following:
Countermeasure 1: Select the door with reliable quality and strong anti-theft ability and the door that is not easy to move for your own house;
Countermeasure 2: Change the outdoor pipe that does not have to use iron pipe to a plastic pipe to reduce the safety of thieves climbing;
Solution 3: Install a built-in safety fence on the ventilation window and the ventilation window;
Countermeasure 4: Change the external anti-theft network into an embedded anti-theft network. If there is an active fire-fighting door or a pull-type anti-theft network, you should pay attention to the lock; install iron bars or barbs in the air-conditioning position;
Countermeasure 5: Improve the surveillance of rooftops and underground garages, block the roof passages between high-rise buildings, and set uniform exports in underground garages.
Drilling BOP And Control System
During oil drilling, it is installed on the wellhead casing head to control high-pressure oil, gas, and water blowout devices. When the oil and gas pressure in the well is high, the blowout preventer can close the wellhead (shut down). When the heavy mud is pressed into the drill pipe, there is a four-way under the ram, which can replace the mud invaded by gas, increase the pressure of the liquid column in the well, and suppress the ejection of high-pressure oil and gas.
Its types are divided into ordinary blowout preventer, universal blowout preventer and rotary blowout preventer. The universal blowout preventer can be activated in emergency situations to deal with any size of drilling tools and empty wells; the rotary blowout preventer can realize the blowout and drilling operation. In deep well drilling, in addition to two ordinary blowout preventers, universal blowout preventers and rotary blowout preventers are often added, so that three or four combinations are installed at the wellhead.
Annular Blow-out Preventer Annular Blow-out Preventer is usually equipped with a large gate with a ram-type blowout preventer. During operation, a sealed annular space is formed between the pipe string and the wellbore. When there is a pipe string in the well, it can also be separated The well is closed, but it will not work after several times of use, and long-term shut-in use is not allowed.
