Cryogenic supports and expansion joints

Cryogenic supports

Cryogenic supports by Ca.S.T.Im. 2000 are particular supports suitable to prop up the piping of those systems that work at a low temperature, which require special insulation and one or more layers of high density polyurethane between the piping and the support itself. There are different kinds of supports, such as saddle support or collar support; the insulating layer can be composed of different layers that can be integral with or released from each other, according to the supply request presented in the customer specifications. It is also possible to use a further aluminium coating and a vapor barrier between the polyurethane layer and the support: the vapor barrier is a bandage of the polyurethane layers with materials suited to the temperatures they should work with.

 

Expansion joints

Expansion joints are elements used to offset the effects of thermal expansion on pipes or equipment.

They can be of different kinds depending on the type of movement or thrust they have to bear.

Metal expansion joints are commonly designed according to the most reliable international standards such as E.J.M.A. (Expansion Joint Manufacturers Association) , ASME VIII app. 26 , PED.

Rubber expansion joints are technically defined with the same approach used for metal ones.

Based on the design conditions, the bellows can be built in:

EPDM, EPDM HT, Nitrile®, Neoprene®, Hypalon ®, Viton®, Spec. Nitrile®,

Nitrile® White, Hypalon®,SBR, Viton®, Cloroprene, etc.

Textile expansion joints are generally used in applications with low temperature where they need low stiffness, with significant strokes (axial, lateral and angular) acting at the same time, in small areas.

The composition of the textile joint can be of different nature (There are about 100 kinds of fabrics and felts of glass, silica, ecological ceramic, wire mesh, P.T.F.E. and rolled fabrics with polymer fluorine) and is highly dependent on the use.
