Metal compensators are divided into several major types: corrugated compensators, sleeve compensators, rotating compensators, square natural compensators, etc. Compensators are also called expansion joints, expansion joints, and corrugated compensators. Among them, corrugated compensators are commonly used to ensure the safe operation of pipelines and have the following functions: Absorb equipment vibration and reduce the impact of equipment vibration on pipelines.
.Absorb the deformation of pipelines caused by earthquakes and ground subsidence.
.Compensate for axial, transverse and angular thermal deformation of the absorption pipe.
. The expansion and contraction of the corrugated compensator facilitates the installation and disassembly of the valve pipeline. How to install a metal compensator
Correctly install a rectangular metal compensator:
First, the pipe must have good neutrality. If there is no other way to ensure it, you can use straight pipe auxiliary installation and then cut the pipe of equal length and then install the compensator. method to ensure.
Second, it should be noted that the compensator does not absorb torque, so the compensator is not allowed to be twisted when installing the compensator.
Third, all movable components of the compensator must not be blocked by external components or restrict the normal movement of their movable parts.
Fourth, for compensators with guide tubes, attention should be paid to making the direction of the guide tube consistent with the flow direction of the medium (install according to the flow direction mark of the compensator). The hinge rotation plane of the planar angular compensator should be consistent with the displacement plane
Fifth, the insulation layer should be made on the outer protective sleeve of the compensator and should not be made directly on the bellows. Chlorine-containing insulation materials must not be used.
Sixth, the bracket must meet the design requirements. It is strictly forbidden to test the pressure in the pipeline before the bracket is installed to avoid damaging the compensator.
Seventh, the compensator allows a system pressure test that does not exceed. parts and adjust the limit device to the specified position according to the design requirements. Enable the piping system to fully compensate for environmental conditions.
Ninth, before installation, check that the model, specification, pipe and support configuration of the rectangular metal corrugated compensator must meet the design requirements.
Tenth, during the installation process, welding slag is not allowed to splash onto the surface of the corrugated pipe, causing the corrugations to suffer other mechanical damage.
Metal corrugated pipes are mainly used to connect pipes in situations where a small bending radius is required for non-concentric axial transmission or irregular turning, expansion and contraction, or to absorb thermal deformation of pipes, or where it is inconvenient to install with fixed elbows. Or the connection between pipes and equipment. Commonly used metal bellows materials include carbon steel and stainless steel, as well as steel-lined, aluminum, etc.
Metal corrugated pipes are made of different metal materials due to their different uses. Because of their different materials, the properties and uses of the processed metal bellows are also different. The materials used to make metal bellows mainly include stainless steel, tin bronze and quilted bronze.
