Heating pipe how to choose to install heating pipe considerations
In the north, many homes are in accordance with the heating pipes, but the installation of radiators is not a trivial matter. In addition to the purchase and installation of radiators, the installation of heating pipes cannot be ignored. Whether the purchase is appropriate and the installation is reasonable will affect the future. The heating effect and useful life. Let's follow along with us to look at the common sense rules for installing heating pipes . [How to choose heating pipe] 1. Heating pipe material, mainly aluminum plastic pipe, PPR pipe and PB pipe. (1) Aluminum plastic pipe has good heat-insulating property, the outer wall is not easy to be corroded, and the inner wall is smooth, so that the resistance to water flow is small, and it can be bent freely. Therefore, the construction is convenient and the cost performance is relatively high. (2) PPR pipe corrosion resistance, heat resistance, light weight, high mechanical strength, easy scaling, long service life. And now there are PPR aluminum plastic pipes on the market, which combine the advantages of PPR pipe and aluminum plastic pipe. (3) PB tube is a kind of polymer inert polymer, with high temperature resistance, durability, chemical stability, plasticity, odorless, odorless, non-toxic, non-fouling, long life and other characteristics, but the oxygen of the PB tube The higher the permeability, the need to block oxygen. At present, all oxygen blocking PB pipes are on the market. Heating pipe in and out of water There are three ways to enter and exit water from the radiator: the top and bottom, the bottom and bottom, and the bottom and bottom. Going up and down: This kind of heating pipe is the most reasonable way to enter and exit the water, high and low out is conducive to the internal hot water circulation, increasing the flow rate of the water, but also need to increase the length of the pipe, affecting the aesthetics of the home decoration. Down in and out: With this type of pipe installation, both the inlet and the outlet are below, which not only maintains the overall shape of the radiator, but also facilitates the connection and laying of the pipes, as well as saving the pipe material. Bring some convenience to family life. Bottom In and Bottom Out: Bottom In and Out Out, the general pipeline will be laid on the floor of the house, only the radiator will be exposed on the outside, it will not occupy too much of the interior space, and enhance the beauty of home decoration. However, this method is more suitable for centralized heating, because the heating pipe pressure is large enough to ensure the normal operation of the water cycle, if it is the best way to do independent heating, otherwise it will indirectly lead to heating heating effect is not ideal. Indoor Heating Pipeline Installation Notes: Pipeline slope requirements: Pipe installation should have a slope, if no design requirements, the slope should meet the following requirements: 1. The hot water heating and hot water supply pipes and soda steam and condensate pipes flowing in the same direction, in this case, the slope of the pipe is generally 0.003, attention can 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. Pay attention to installing exhaust and drain devices 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. Set metal or reinforced 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 casing must meet the following two conditions: 1. The sleeve installed in the wall should have two ends parallel to the wall finish so that the pipe will not be affected during the expansion and contraction. At the same time, if water accumulates on the ground, it will not flow to the lower floors. 2, the casing installed in the floor, the bottom should be parallel to the bottom of the floor, the top should be 15-20 cm above the ground. Summary: The above is about the installation of heating pipe content, for more information, please continue to pay attention to this site information.

CA Temporary Fence Introduction:
Temporary Fence is also called
Construction Fence,Removable Fence and Portable Fence. This type was
very popular in Canada, the United States, and some other America
countries.
It is quick to be set up and easy to move and is ideal for restricting
access or containing a site and is commonly seen at construction sites,
public events, as a dog run, or anywhere crowd control is important.
It offers the benefits of affordability and flexibility.
