The drain joint is one of the indispensable fittings in the steam pipeline. The drain joint is also known as prefabricated insulation and drainage joints, moisture-proof drainage joints and external corrosion protection. Well-insulated steel pipes are coated with an external anti-corrosion treatment. In prefabricated direct buried steam pipelines, the low cost is the preservative of epoxy coal tar brush coating wrapped cloth, such as two cloths, three cloths and five layers of oil. It can also be made into 3PE or glass. FRP resin is anticorrosive, both of which are costly. Hydrophobic joint sealing and other properties. The corrosion protection of FRP or epoxy coal tar asphalt paint ensures the service life of the pipeline. CJ / T5037 standard, regular drainage is controlled by thermal power trap. Hydrophobic joints are prone to condensate during the operation of steel jacketed steam-insulated steel pipes, which requires the device to concentrate and exclude internal working pipes. The hydrophobic joint has good sealing performance, no leakage, good thermal insulation effect, and is convenient for environmental protection and energy saving. Among them, glass wool insulation cost is relatively low and widely used. Each layer of insulation cotton should be wrapped with a reflective layer of aluminum foil. The corresponding winding thickness is bundled with steel tape.
Steel strips cannot be fastened with steel plates, in order to avoid loose insulation and falling off during use, which affects the service life. The above is all about the drainage joint is an indispensable pipe fitting of the steam pipeline. If there is anything you don't understand, you can directly communicate with our customer service, we will serve you wholeheartedly. The inner sleeve of the steel sleeve steel hydrophobic joint is selected with a second-degree inorganic zinc-rich primer (temperature resistance ≥400 ℃) anti-corrosion coating, and the pipe port is sealed with polyethylene film or three-layer PE cold-wrap tape to prevent entry into the moisture or installation water. Multi-layer staggered banding of thermal insulation material effectively reduces heat loss, and at the same time controls the surface of the jacket to prevent the occurrence of cold bridges, thereby ensuring the temperature control of the jacket anticorrosive layer. Using insulation materials to wrap multiple layers of aluminum foil reflective layers effectively reduces heat loss and makes steam pipes more economical and reasonable. The difference between the upper drainage type and the lower drainage type of the steel sleeve steel drain joint is divided into two types, one is the upper drainage type, and the other is the lower drainage type.
The difference between the two is that the tidal outlet is different, and the setting of the drainage well is also different. The steel sleeve steel drainage system is set at the drain port of the compensator or as close to the fixed bracket as possible. If the drainage system is installed on the pipeline, a water collection tank should be installed on the pipeline first, and then lead out with a metal hose. Two branch tubes are listed in the back to the hydrophobic operation well, one is to start the hydrophobic, and the other is the regular hydrophobic. Recurrent drains are controlled with thermodynamic traps. Then introduce drainage wells or manholes. It is recommended that the operation well be separated from drainage to facilitate operation and avoid danger. Introduction of steel sleeve steel fixing bracket, what is its structure? The steel sleeve steel fixing bracket adopts a common internal fixing structure. The three-layer steel flange and the two-layer asbestos flange are used to maintain the relative fixation between the front and back steel pipes. The high-temperature partition materials are useful to avoid the occurrence of cold bridges, and there is no need to add reinforced concrete structures during construction. . The relative fixing of the front and back steel flanges can accept a sufficient axial thrust according to the design requirements, and the steel sleeve steel fixing bracket can fully ensure the safe operation of the entire pipeline.
The waterproof seal structure. In order to maintain the rationality of the thrust of the fixed bracket and the stability of the implement during pipeline operation, it is proposed that the compensator be symmetrically arranged at both ends of the fixed bracket, and a guide bracket be added at each end of the compensator to ensure that the compensator only receives axial thrust. Extend the life of the compensator. Insulation prefabricated parts are made in the prefabrication plant, and welding repairs on site may be performed on site for heat preservation and anticorrosion. The diameter of the steel sleeve steel sleeve is larger than that of the mother tube. The length ratio value is also particularly high. After the appearance of various steel sleeve steel steam insulation pipes in the mall, the innovation on such a skill is still very effective. How do you make this practical? The key lies in the social and economic benefits, because a variety of thermal insulation effects can be better demonstrated in this process. Therefore, as a useful method in the process of heating and energy saving, after entering the shopping mall, gradually introducing a new starting point for such heating pipes. Aiming at the advantages of steel jacketed steel steam insulation pipes, the first is to innovate requirements, and to better develop such functions, quality, and related advantages.
