First, the characteristics of slotted reducer tee
1, quick installation. Grooved pipe fittings only need to be installed with supplied standard parts, without subsequent work such as welding and galvanizing, so the installation speed is obviously faster than that of threaded connection and flange connection, and the pipeline can be automatically centered and centered by fixture, which can greatly improve the construction efficiency and effectively shorten the pipeline installation cycle.
2, safe and reliable. On the one hand, the grooving machine and the hole opener used in the installation process are special tools provided by the manufacturer, which can ensure the machining accuracy of the pipe end groove; On the other hand, the sealing ring in the inner cavity of the clamp plays the role of grasping the pipeline and realizing self-tight sealing. The greater the internal pressure, the better the sealing performance. The nominal pressure of pipe fittings can be as high as 2.5MPa.
3. Easy installation. Grooved pipe fittings need fewer bolts to fasten, which is convenient to operate. Only one wrench is needed for disassembly and assembly, and workers do not need special operation skills, so they can go to work after training.
4. Economy. Grooved clamp connection will not damage the galvanized layer, and the pipeline does not need secondary installation, galvanizing and handling, so the installation cost is greatly reduced. Its installation speed is fast, which can shorten the construction period, make the project put into use in advance and create economic benefits in advance.
5. environmental protection. The piping and installation of grooved pipe fittings do not need welding or open flame operation, so there is no welding slag pollution, no damage to the galvanized layer inside and outside the pipe, no pollution to the construction site and the surrounding environment, and it is conducive to fire prevention. Groove connection reduces the transmission of noise and vibration due to the gap between pipe ends.
Second, how to install the groove reducing tee?
1. When ordering groove parts, select the appropriate sealing ring. Different media in the pipeline need sealing rings of different materials. At present, there are eight kinds of sealing rings with different materials on the market to adapt to different media.
2. Pipe groove (also called rolling groove) is the key process of pipe connection, and it is also an important link to determine the connection quality of groove parts. The width and depth of the groove must meet the requirements. When rolling the groove, the end of the nozzle should be smooth and burr-free, and the port should be perpendicular to the pipeline axis, so that the rolling groove can be perpendicular to the central axis of the pipeline, and the length from the groove to the pipe end should be equal. If the ellipticity of the pipe and the wall thickness of the welded galvanized pipe are uneven, they should be corrected as much as possible when rolling the groove, otherwise the groove depth is uneven and its tightness cannot be guaranteed.
3. For the groove connection of seamless steel pipe, galvanized products from regular manufacturers should be selected. If seamless steel pipe is purchased and then galvanized, the quality of galvanized steel pipe is usually not guaranteed due to oxidation corrosion caused by long-term storage, and the adhesion of galvanized layer is poor, so the galvanized layer is easy to crack or even fall off during grooving, which affects the sealing and service life.
The above is the characteristics of groove reducing tee introduced by Bian Xiao and how to install groove reducing tee. The installation of groove reducing tee is very simple and fast, which can shorten the construction period. You can use this equipment when installing pipes indoors.
