And the heating tablets, i'm sure we're all getting to know each other better, and it's important for people in the north to have the heating table. There's a lot of information about the installation of the heater, for example, the cover of the heater, the cover of the heater, there's a lot of information about the cover of the heater. Here's a little part of the story about the heat pipe。
First, the materials for heating pipes, which generally include ppr tubes, aluminium plastic tubes and pb tubes。
1. Ppr tubes are corrosive, good heat-resistant, of light quality, of high mechanical strength, and are not easy to decompose and have a long useful life. And now there are ppr aluminium tubes on the market, combined with the advantages of ppr tubes and aluminium tubes。
2. Aluminium plastics tubes are warm, the outer walls are not perishable, the inner walls are smooth, so they are less resistant to the flow of water and can bend at will, thus facilitating construction and offering a higher value。
3. The pb tube is a high molecular inert polymer with high temperature resistance, persistence, chemical stability, plasticity, odorlessness, smell-free, non-toxic, non-stereogenic and long-lived properties, but the oxygen penetration of the pb tube is high and requires oxygen resistance. The market is now full of oxygen-resistant pb tubes。
2. The length of the heating pipe and the choice of the pipe path will have to be chosen according to the circumstances, and the more the general pipe is fine, the longer the pipe, the greater the resistance and the lower the flow speed。
(a) the first step is to carry out, together with the technicians of the heating tablets, an on-site survey design to determine the type, number of fragments, mode of access to water and the specific location of the heating tablets, to determine, on the basis of actual circumstances and in communication with the owners, the type, group, group and location of each set of units, etc., and to enter into a contract with the seller for the purchase and sale of the heating tablets;
Step 2: to conclude a construction agreement with the heating unit to ensure quality and risk of construction, the general construction unit shall state on the construction agreement that the heating system will be constructed for at least one heating season. It would be best if the heating chip sales and construction units were the same unit。
Step three: phase one of the construction work for the installation of the heating tablet. The installation of the heating chips was divided into two steps: phase one and phase two. The first phase of the heating project includes the positioning of the heating equipment, the opening of the tanks, the plumbing (or the modification of the plumbing), the pipe connection (the welding tube), the installation of the collectors, pressure testing, etc.; phase ii includes the installation of heating chips (fixed suspension of the heating tablets, valves connected to the heating tablets and heating pipes), system-wide pressure detection and the commissioning of the heating tablets。
These are the knowledge of the underground heating pipes presented by the it encyclopedia. By looking at the shorthand, you should know a lot about the cover-up of the heating pipes, the installation of the heating tablets is important, and the installation of the heating tablets has many advantages, making it easier to install them, but it is important that you have some knowledge of how to install them。
