The installation process of the radiator directly affects the heating effect of the radiator. The so-called details determine the success or failure. The installation of the boiler and radiator is very important. The connection of them and the installation of the heating pipeline can not be sloppy. The following Xiaobian specifications for the installation of heating pipes According to the introduction, the installation of radiators needs to be carried out in accordance with relevant regulations. What should be noted about the installation of indoor heating pipes? Let's go and see it together.
Heating pipe installation specification
First, the installation of radiators
When carrying out systematic layout of radiators, they should cooperate with the requirements for the use of buildings, the heating system diagrams, and the arrangement of radiators, so as to save the pipes and facilitate the installation and maintenance.
Radiator piping is usually installed in the clear, when the use of surface mounted, it should be arranged in the corner of the wall and the window wall. Before the supervisor installs, place the radiator in place, find the flatness, and then install the riser so that the size of the supervisor can be accurate. The semi-circular bends on the double risers should be accurate and flat. The branches should not be wrong or wrong in the middle of a semicircle bend. After the pipeline is installed, check whether the coordinates, elevation, reserve port position, and pipeline diameter change are correct. Then, straighten the slope and calibrate the review slope with a level ruler. After the adjustment is qualified, adjust the elevator card bolt U-shaped card to make it tight. Appropriate, flat and consistent, the final welding fixed block card stop.
Second, the radiator pipe installation
The installation of the radiator pipe is usually carried out in a concealed manner. The concealed or semi-tight radiator pipe branch lights and fork bends must be adapted to the corner of the radiator slot to achieve a beautiful effect. The branch pipes connecting the radiators should have a slope. For the next time, the next branch of the water supply pipe slopes to the radiator, and the return branch pipe to the riser; the next lower double pipe has no exhaust device on the top water supply riser, and the supply and return branch pipe slopes to the riser. Other layers The water supply branch slopes to the radiator, and the return branch pipe runs to the supervisor.
Radiator branch pipe installation should be done after the radiator and standpipe are installed or at the same time as the standpipe. When the radiator pipe branches over the wall, in addition to the addition of casing, it should also be noted that the pipe cannot have joints in the wall. When the valve is installed on the branch pipe, the side close to the radiator should be connected with the detachable part. When installing the radiator branch pipe, the steel pipe must be properly adjusted and then meet to prevent the branch pipe and the riser from getting scratched.
Heating pipe installation precautions
1, pipe slope requirements
The installation of pipelines should have a slope. If there is no requirement for design, the slope should meet the following requirements: 1. Steam and condensate pipelines with hot water heating and hot water supply pipes and soda flowing in the same direction. In this case, the slope of the pipeline is general. For 0.003, note that it must not be less than 0.002; 2. Steam and condensate pipes with reverse flow of soda water generally have a slope of less than 0.005.
2, pay attention to install the exhaust and drain device
During the installation of indoor heating pipes, the pipes pass through doors and windows or from other openings, beams, columns, corners, etc. If the corners of the pipes go above or below the horizontal direction of the pipes, they should be at their highest or lowest point respectively. Install the exhaust and drain fittings so that the main function of the installation is to remove the air in the pipes and the dirt at the lowest point.
3, set the tin or steel casing
When the pipeline passes through the floor and the walls, it should be provided with a metal sheath or a steel casing. In this process, the bushing must meet the following two conditions: 1. The bushing installed in the wall should have both ends parallel to the wall finish so as to ensure that the pipe is not affected by the expansion and contraction. influences. At the same time, if there is water accumulation on the ground, it will not flow to the lower layer; 2. The casing installed in the floor should be parallel to the bottom of the floor, and the top should be 15-20 cm higher than the ground.
Conclusion: The relevant information on the installation guidelines for heating pipes and pipe installation precautions was introduced here. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.
