In the experience can not relax, today Xiao Bian and everyone to take a look at the installation method and precautions of marble window covers.
Window cover installation steps and precautions
Window cover construction preparation
1. Material
(1) Wooden window coverings and lines should be made of wood of the same tree species as the window frames. The moisture content should not exceed 12%, and there must be no defects such as cracks, distortions, and dead knots.
(2) The processing of wooden windows with cheeks, face piers and lines shall be carried out according to the specifications and lines required by the design.
2, operating conditions
(1) The window frame should be installed before installing the face plate and the line, and check the installation position is correct.
(2) Before installing the face plate and the line, the installation site should be finished with gray or finish the surface decoration.
(3) The floor should be completed before installing the face plate and lines.
Window cover installation steps
1. Check the leveling of the seam between the plaster and the window frame on the face plate and the line mounting area. According to the position of the face plate or the line, the length or joint of the face plate or the line shall be prepared, and the corners shall be diagonally connected at an angle of 45 degrees. Should be pre-installed so that the face plate covered plaster and other surface layer, the cover width of not less than 10cm. The nails should be fastened firmly to the installed window frame, and the nail caps should be flattened. The spacing of the nails is determined by the species, material, and section size of the face plate and the line. It is generally 400 mm.
Window cover construction process inspection standards
1, ensure the project
(1) The types of trees used in the production of face plates and lines shall be in accordance with the design requirements for the size, shape and shape of the processing.
(2) Sticking the face plate and lines should be nailed to the door and window frame when installing.
2. Basic items
1 The production size is correct, the line angle is clear and straight and smooth.
2 The installation position is correct, the seam has no wrong side, and the cutting angle is neat and the angle is the same.
3, allow deviation project
The allowable deviation of the distance from the inner edge to the window frame trim is 2mm. Check with the ruler.
Window cover construction considerations
1. Lax seams, inaccurate cutting angles: pre-assembly should be strengthened and defects should be repaired in advance when they are pre-installed.
2. Inconsistent and inconsistent: Inconsistent specifications of the face plate and the line processing, and the installation and operation are inaccurate. When installing the ingredients, the same specifications should be selected at the same place where the same part is connected. During the operation, you should fix the joint after aligning the joints.
3, nail cap can not be exposed on the surface of the window cover.

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.
