Seamless steel tube according to the standard is divided into ordinary, near standard, national standard three standards. Seamless steel tube needs to cover the pressure blue and the middle part of the sealing ring have certain standards.
The flange cover of these three standards are ordinary 6kg, 10kg near standard, 10kg national standard, seamless steel tube must be based on the concrete floor of all the tube fixed position to stop reasonable equipment, and according to practice to indicate the location of all the tube location.
Seamless steel tube plugging in seamless steel tube, in order to better avoid concrete into the coming in, must ensure the following aspects:
1. After the installation of the beam casing in the concrete floor and column is carried out in cooperation with the civil engineering, flexible materials such as newspapers and embroidered pillows should be used to fill the concrete before pouring the concrete, so as to avoid blocking caused by mortar entering the casing and wiring terminals.
2. In order to avoid outdoor surface water or precipitation into the basement according to the seamless steel tube, it can ensure that the installation equipment has a good natural environment for engineering construction. Therefore, the seamless steel tube out of the basement wall in addition to the selection of flexible material plugging, seamless steel tube prefabricated components production and processing, should be in the casing end number selection of thick steel plate welding welding plugging, to be opened when the seamless steel tube installation.
3. The tubeline through the moisture-proof wall, should follow the structure embedded parts stiffness or soft seamless steel tube.
4. The tube through the wall, through the concrete floor, through the flat roof should be embedded with the structure of the hole, after the construction of the construction project to carry out the casing laying, through the wall embedded casing on both sides must be good sealing tape
5. The tubes and U-shaped tubes at type I air defense concrete floor slab, air defense wall and air defense diffusion chamber shall be sealed with embedded parts.
According to the user’s engineering need to take the corresponding production standard, under normal circumstances the flexible pressure on the seamless steel tube is limited, if under the condition of the engineering requirement according to strict standard is used to make, so for small engineering piping run basically won’t produce vibration, the pressure generated by a medium for product poses, You can use the near standard or ordinary standard to make, so that you can play a large performance of the product, while avoiding the waste of resources. Whether using national standard or non-standard production of flexible seamless steel tube, are based on customer requirements and engineering demand for quality
