Rectangular metal expansion joints have a variety of applications in the power, petrochemical, refining, chemical, and steel industries.
Our rectangular hoses have following features:
1.Customized design
Since there are no standard duct sizes, and due to the wide range of pressure and temperature combinations, we will design each rectangular metal expansion joint for our customer to provide the most economical design that will absorb the thermal movements of the system in which it is installed.
2.Larger movement absorb
Like circular expansion joints, rectangular expansion joints absorb three types of movement: axial, lateral and angular. For the purpose of designing rectangular bellows, it is critical to know in which direction the lateral and angular movements will occur, i.e. parallel to the long and/or short side of the bellows.
Unlike circular bellows where the pressure stress is a circumferential membrane (hoop) stress, the rectangular bellows must be designed for longitudinal (beam) bending stresses. Long unsupported lengths must frequently be supported to prevent excessive deflection and stresses of the bellows element. In certain applications, covers and liners can perform the function of pressure supports.
3. U-type convoluion profil
The "V" convolution profile will be supplied with single miter corners, unless otherwise specified. Round corner bellows will always be constructed using the U convolution profile .
