Main pipe

The limb length a depends on the length l. Length b is based on the possible movement of the main pipe. The total length

a + b must be surrounded with expansion pads. Expansion of the main pipe is also possible on connections in the adhe-

sion area due to subsequent repair work, so expansion pads should also be installed as a precaution. The thickness of the

expansion pads which are necessary in such cases can be reduced if the connecting pipes are still exposed and can be

aligned under low stress when the main pipe is pre-stressed.
