Installation and product identification of pipe supports and hangers? 1. Installation of air duct supports and hangers 1. The installation of air duct supports and hangers must be accurate, and the specifications of expansion bolts are the same as those of suspenders. 2. Hanger spacing: horizontal installation of air duct: not more than 3m. Vertical installation of air ducts: the spacing is not more than 4m, and a single straight pipe should have at least 2 fixed points. 3. The supports and hangers should not be installed on tuyeres, valves, inspection doors and automatic control mechanisms, and the distance from tuyeres or plug-in pipes should not be less than 200 mm..4 4. When the length of the horizontally suspended main air duct and main air duct exceeds 20m, a fixed point to prevent swinging should be set, and each system should not be less than 1. 5, fire damper diameter or long side size is greater than or equal to 630mm, with independent steam-hanger. 6, insulation duct bracket should be located outside the insulation layer, cross arm stow-wood to prevent cold bridge. 7, hanger screw hole should be machined. Derrick should be straight, thread integrity, bright and clean. 8. For air ducts hoisted with channel steel heads, double nuts should be added to the exposed heads on the channel steel. Install and hoist the basement, add a nut above the cross arm of the air duct and a double nut below the cross arm. 9. Schematic diagram of hanger installation is as follows: II. Installation of pipe supports and hangers (I) General Provisions The installation of supports and hangers shall be smooth and firm, and shall be in close contact with the pipeline. At the joint of pipeline and equipment, independent supports and hangers shall be set up. The supports and hangers of the main pipe and trunk pipe in the system piping room shall adopt load-bearing anti-sway pipe racks; The pipe supports connected with the equipment need to be damped. When single-rod hanger is used for branch pipe support, load-bearing anti-sway hanger shall be set at the starting point of pipeline, valves, tees, elbows and every 15m length. For the vertical pipes in the shaft, a guide bracket is set every 2F. Insulation pipes, supports and hangers shall be lined with wood after anticorrosion treatment, and the thickness shall be the same as that of insulation layer, and the surface shall be smooth. Gaps between the joint surfaces of the gasket are filled. The spacing between horizontal supports and hangers of steel pipeline is shown in the table: (2) The main supports and hangers of steel pipeline are installed as1; Schematic diagram of horizontal fixed bracket installation: schematic diagram of pipe clamp installation; 4. The connecting pipe hanger in the machine room adopts damping spring hanger, and the selection of spring hanger is based on the weight of the pipe and the vibration frequency of the connecting unit. The installation diagram of the product is as follows: 5. The structural design of portal composite steel frame of pipe rack layer will provide detailed calculation after entering the factory. The following figure shows an installation example: (3) Schematic diagram of the installation of steel supports and hangers on steel beams: steel beam clips 2 storage clips 3 adjustable pipe clips 4 expansion anchor steel beams (4) C-type hangers for connecting electrical pipelines with steel structures are as follows: (3) Pipeline identification? 1. Summarize the electromechanical pipeline identification system often used in large buildings at home and abroad. The main function of pipeline identification is to divide complex electromechanical pipelines into systems through various pipeline identification, so that building managers can carry out relevant emergency repairs and reasonable daily maintenance in a short time, and at the same time increase the aesthetic effect of electromechanical pipelines. 2. Pipeline identification? Our company's enterprise identification standard is in the form of database. Through the comprehensive analysis and comparison of various standards, the size and direction of data such as color, font, letters and arrows of relevant pipeline signs are sorted out. At the same time, our company can modify the electronic version of the owner's special requirements through digital hot melt printing equipment until the owner is satisfied. The left picture shows the staff using our own digital hot-melt printing equipment of Brady Company in the United States, and the following picture shows the real-life photo of pipeline marking effect in Motorola workshop project. 3.( 1) Compared with conventional pipe labels, ordinary self-adhesive tape has no resistance to impurities such as oil, water and dust on the surface of the pipe, and it is not firmly bonded and is easy to fall off and be damaged. The logo material provided by our company is polystyrene tape, and its adhesive strength has been strictly tested by American professional laboratories. This high-quality product can be used on dirty, oily and uneven pipeline surfaces, with good texture, firm bonding, water resistance and corrosion resistance, and should not be damaged. Figure 4 on the upper right shows the sample of polystyrene tape: (2) Compared with the conventional adhesive for pipeline identification, the service life is very short, and the identification begins to fall off and fade soon after many engineering applications, and this phenomenon still exists after re-pasting. After 72 hours of use, the strength of the logo provided by our company reached the best state, and the average life span of outdoor use (3) Comparison of the scope of use. Conventional pipeline signs are mostly used in buildings, which have strict requirements on environment, temperature, humidity and pipeline materials. The logo provided by our company can be used indoors and outdoors, and is suitable for all kinds of harsh environments with the highest temperature of 82- the lowest temperature below zero 18. At the same time, it can be used in various industrial conditions with acid and alkali corrosion. (4) Cost comparison: the price of conventional pipeline marking is generally low because of the use of ordinary self-adhesive tape, and the marking system provided by our company is relatively high because of the use of high-quality polystyrene tape and various color ribbons; However, ordinary self-adhesive tape has a short service life and needs frequent maintenance and replacement.
