Corrugated compensator installation specification

In the design of the pipeline itself compensation there is a natural compensation, corrugated compensator is the use of natural bending shape of the pipe has the flexibility to achieve the role of this displacement, but the length of the function of this natural compensation is often limited, the amount of compensation required in the general pipeline are greater than the amount of natural compensation,so in order to prevent this destructive phenomenon from occurring it is necessary to install corrugated compensators in the piping system. The installation of the compensator should comply with the following provisions.
(1) the compensation amount and installation position of the compensator should be in accordance with the requirements of the design documents, and should be pre-tensioned or pre-compressed according to the design calculation of the compensation amount.
(2) bellows expansion joint or compensator with a welded end inside the set, the horizontal pipeline should be installed at the inflow end of the water flow, and the vertical pipeline should be installed at the upper end.
(3)The packing type compensator should be concentric with the pipe and should not be skewed.
(4) the compensator end of the pipe should be set up fixed bracket, the structure form and fixed position should be in line with the design requirements, and should be fixed before the pre-stretching of the compensator.
(5) sliding guide bracket set position should be in line with the requirements of the design and product technical documents, pipe sliding axis should be consistent with the compensator axis.
After the installation of the compensator, the compensator fixed bolt on both sides of the inner screw loosened 3-5cm, the bolt on both sides of the outer screw locking, so that the compensator in the pipeline occurs under the principle of heat win cold shrinkage can be expanded and play a compensating role.
