|
| |
|
|
| |
Pressure ranges up to 06 kg/cm2
(special units for higher pressures) These are the simplest form manufactured from single and multi-ply elements and fitted with either flanges or pipe ends these units are suitable for axial movements only though in certain cases will take care of small lateral offset also. |

|
| |
|
|
| |
Pressure ranges up to 25 kg/cm2 & above two bellows elements are joined together by a center tube and fitted with either pipe ends or flanges. The assembly is capable of both axial and lateral movements but is limited to low pressure applications because of center tube instability. |

Hinged Expansion Joints |
|
| |
|
|
| |
Pressure ranges up 40 kg/cm2
Generally installed in multiples of two or three, there joints are designed for angular movements in one plane only. A hinged mechanism contains the pressure loads and ties back to an integral flanger or box restrained lug. Limit stop controls the degree of angular movement. These units can be fitted with either pipe ends or flanges, can be supplied with two hinged system also. |
