Performance Of Pipe Expansion Joints

A pipe Expansion Joint is a joint that compensates for dimensional changes in the pipe joint due to thermal expansion and contraction. There are two types of pipe retractors commonly used, one is a rubber pipe retractor, and the other is a metal pipe retractor. The main feature of the metal pipe retractor is that the telescopic compensation is large, the temperature is high, and the pressure is high.
There are strict regulations for installing Stainless Steel Expansion Joints. When installing, pay attention to the setting and stress of the fixed bracket. When the pressure is pressed, the telescopic end of the retractor should not be pulled out due to cracking of the fixed bracket; the design department must design and install, otherwise the pipeline is prone to problems. Pay attention to the setting distance of the guide bracket. A good guide bracket should be installed at a distance of 4D (4 times) from the compensator. The second guide bracket should be installed at a distance from the compensator 14D. The three points can be arbitrarily set.
