Grooved pipe fitting is a new type of steel pipe connecting pipe fitting, also called clamp connection, which mainly includes two categories of products:
1. Pipe fittings with sealing function include rigid joints, flexible joints, mechanical tees and grooved flanges.
2. Pipe fittings used to connect the transition, including elbows, tees, crosses, reducers, blind plates, etc.
Second, the characteristics of grooved pipe fittings
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, simple 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. In addition, the installation speed of grooved pipe fittings 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 and 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. In addition, due to the gap between the pipe ends, the transmission of noise and vibration is reduced.
6, convenient maintenance
Trough fittings can be pre-assembled and adjusted at will before bolts are locked. The piping sequence is non-directional and can be operated in a relatively narrow workspace and place. It is very convenient to clean and replace only two connectors during maintenance.
3. What is the material of the fire trough pipe fittings?
Grooved pipe fittings have a wide range of applications, generally mainly used for fire water pipes, so they are also called fire grooved pipe fittings. What is the material of grooved pipe fittings for fire fighting?
Generally speaking, grooved pipe fittings used in fire fighting field require high mechanical strength and fire resistance, and most of them are made of ductile iron. Besides fire water supply pipes, it can also be used for heating pipes, industrial production pipes, outdoor rainwater drainage pipes of high-rise buildings, etc.
