 Rectangular Bellows Expansion Joints are made from press brake forming. We can manufacture rectangular expansion joint having no size limitation. These type of expansion joints are provided with various configuration of corners viz. round, single miter, double miter and camera corners.
   Rectangular metal expansion joints have a variety of applications in the power, petrochemical, refining, chemical, and steel industries. Since there are no standard duct sizes, and due to the wide range of pressure and temperature combinations, each rectangular metal expansion joint is custom-engineered to provide the most economical design that will absorb the thermal movements of the system in which it is installed. 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.  Â
   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. Typical convolution geometry's and corner
construction details are shown below. 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.
1. Absorbs axial and lateral movements
2. Variety of bellows geometry (for long straight sides)
3. Normal guiding is required
4. Manufactured for a wide variety of materials
   As a leader in expansion joint technology, we
strictly follow quality control procedures to ensure that our
products meet industry standards as applicable: GB/T*********8,
GB/T*******3 and EJMA. And all the products should be strictly
tested from purchasing to delivery,about the service, we can assist
you with your bellows and expansion joint emergencies in a timely
and attentively manner.Beijing Spaceflight Xinghua Corrugated Tube
Manufacture Co.,Ltd has earned a reputation for outstanding
customer service and satisfaction unmatched in the industry.
