In our models of the double bellow expansion joint we have numerous benefits over a standard single bellow design; The double bellow design gives much higher modulus of expansion in the axial, lateral, and angular direction that makes our product ideal for piping systems subject to multidirectional forces; Our company’s flow liner technology is incorporated into the double bellow expansion joint and reduces turbulence and erosion of the piping system improving flow efficiency. The double bellow expansion joint is complemented with this new feature alongside our enhanced collar construction; features that are capable of withstanding some of the harshest operating conditions to increase the joint’s operational durability and decrease the amount of time needed for its maintenance.

The ChangYuan Flex Co. double bellow expansion joint is therefore characterized by flexibility as a major feature. These joints come in a variety of materials and may include high grade stainless steel and/or highly specified special alloys to meet the specific environment of the location. They include the double bellow expansion joints that can handle the hight temperature steam lines in the power plants or the aggravated chemical processes in the refineries. In its end connections therefore the product can be flanged, welding or threaded depending on the existing facilities that it is to connect to. Due to this versatility in design and usage, the double bellow expansion joint is a crucial part for engineers who wish to enhance the piping systems’ performance in their production in several fields.
