Product Description

  

Thermal expansion in pipelines,ducts,and vessels which carry hot or cold fluids,or which are exposed to large variation

in ambient temperature, is a major problem conforing designers. As the metal temperature of the pipe, duct, or vessel increases and decreases,its length also varies due to thermal expansion or contraction .Therefore, unless compensation is provided for these dimensional changes, high stresses will be induced in the piping, ducting, or vessel and large forces will be transmitted through the system to  anchors and connected equipment.And your system must run at maximum efficiency.

The specially designed  metal expansion joint can  absorb the different movement as follows:

Manufacturing capacity:

 

DN:                                          8mm-10000mm                                             

Thickness:                             0.15mm-70mm                                             

Forming method                   Hydraulic forming                                           

Pressure(MPa):                     -30 MPa(metallic)   -0.2MPa(nonmetallic)

shape:                                     U     V   S type Etc.                                        

Temp.(oC):                             -196 to 1400

SINGLE TYPE EXPANSION JOINT-UN TIED

This is the simplest form of expansion joint, of single bellows construction, designed to absorb all of the movements of the pipe section in which it is installed. According to operated pressure of a device, this model is manufactured with or without the shrink ring.

Advantages

 

Inexpensive

Easy to install

 

Low maintenance.

Absorbs all three types of movement.
