2. The sealing of the floor heating system must be checked before paving.
3. The ground must be dry (can be judged by experimental phenomena) The moisture content of the cement floor should be less than 1.5%. The indoor humidity should not be too large. Regardless of whether there is geothermal heating or not, the ambient humidity is preferably about 60 degrees before and after the device.
4. It is strictly forbidden to nail on the ground during construction. After construction, the ground is also prohibited from nailing to prevent damage to the heating coil.
5. Before laying laminate flooring, apply EPE composite membrane (EPE composite membrane must be marked with special words for floor heating) to isolate moisture, so that moisture can be released from the surrounding skirting board.
6. The keel should not be laid. The small thermal conductivity of air will affect the cooling effect and may damage the pipe.
7. When the floor is laid, special floor heating glue must be used to increase the time and effect of use. Moreover, there is no need to worry about the emission of harmful gases.
8. Leave expansion joints between the floor and the wall and use a skirting board that is thicker than the current floor.
9. Pave the floor and the equipment skirting board in two separate constructions. 48 hours after laying the floor, until the glue is completely dry, remove the fastener and then do the skirting board.
10. The floor will only warm up after 24 hours of installation.

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.
