The installation of directly buried polyurethane insulation pipe joint Hebei Runtai Polyurethane Limited gongsi can send personnel to the project site to practice the heat preservation work of the joint, including the installation of the outer casing of the joint, the connection and sealing of the outer casing of the joint with the supervisor and the foaming work of the on-site joint, but it does not accommodate the welding of the joint bu pipe. The main results are as follows: (1) in this mode, the joint casing selects the polyethylene casing with the same material and density as the prefabricated thermal insulation pipe casing, and the heat shrinkable belt is selected between the polyethylene joint casing and the main pipe to connect and seal to guarantee the watertightness of the joint. Then the joint foaming is carried out in the foaming hole on the joint bushing. after foaming is realized, high-density polyethylene is selected to seal the foaming hole by patch or hot melt welding.
Generally speaking, the horizontal sunshade with an outdoor south elevation of 45 °can easily cover 68% of the solar radiation heat. Installed in the window inside the curtain, soft 100 pages and other sunshade facilities, most of the solar radiation heat absorbed by it is distributed to the indoor air. The sun visor installed on the outside absorbs most of the radiant heat and distributes most of the outdoor air, thus reducing the impact on indoor temperature. Therefore, the use of external sunshade (sunshade) is the best way to save energy in buildings.
A few days ago, the trendy Community Marketing Summit Forum (Guangzhou Station) was successfully held. Professor Duan Chunlin, professor and doctoral supervisor of the School of Journalism and Communication of South China University of Technology, shared a speech on the theme “how to use community marketing to build a good brand recognized by consumers”.

Zhanjiang external sliding steel sleeve steel steam insulation pipe technology is to win all-through pipeline for you to analyze the prefabricated directly buried insulation pipe repair method should pay attention to: 1, the construction should avoid the immersion of groundwater and Rain Water, if the end is inadvertently immersed in water, it should be dried before connecting the jacket. 2. The pipe should be stored in a flat site, neatly placed, and the height of the pipe should be less than m. 3. Pipe hoisting is light and light, collision and throwing are prohibited, and straight hoisting of steel wire rope is prohibited. 4. The thermal insulation layer and anti-corrosion coating should avoid direct contact with flame. For on-site installation, please follow the following procedures: pipe trench excavation-base treatment (drainage, sand cushion)-lower pipe-steel pipe welding-inspection (water pressure)-installation (pressure test)-foaming-sealing foam cell. Joint installation, the heat preservation work of the joint is carried out on the project site, including the installation of the joint outer casing, the connection and sealing of the joint outer casing with the supervisor and the foaming work of the on-site joint, but does not include the welding of the joint part of the steel pipe.
Our factory can send personnel to the project site to carry out the heat preservation work of the joint, including the installation of the outer casing of the joint, the connection and sealing of the outer casing of the joint with the supervisor and the foaming work of the joint on site, but it does not include the welding of the steel pipe of the joint.
