When using pipelines of big length surely it is necessary to consider the fact that the coefficient of thermal deformation of metal considerably increases with a pipe length, so use of compensators is necessary. In many systems two-section bellows-sealed shift and axial DLTKF compensators which allow to compensate the loading arising at thermal expansion are used. Very important the fact that compensators of this kind work in two planes - axial and shift. Such compensators are tight and protect the pipeline from deformations.
Depending on the environment of use and conditions of installation the branch pipe can be made both of stainless steel, and of Art. 20 that allows to use it both under welding and for a threaded connection. The internal casing and the bellow valve are made only of stainless steel of brands 12X18H10T, 08X18H10T. Use of quality materials and reliability allows to use two-section bellows-sealed shift and axial DLTKF compensators in rather wide range of working temperatures - from-260 to +700ºС. At the same time can act as a working environment both water, and steam and even aggressive liquids.
