Directly buried thermal pipeline compensator is a special compensator specially designed for directly buried thermal pipeline. Its main function is to absorb the axial displacement of pipeline due to temperature change, so as to reduce the stress in pipeline system and prevent the damage of pipeline due to thermal expansion and contraction. This kind of compensator usually adopts bellows structure, which can withstand the pressure of soil in underground environment, and has certain bending resistance and long service life.
Characteristics
bending resistance: The directly buried compensator is designed with strong bending resistance, and can work normally even when the pipeline sinks.
Large amount of compensation: It can provide a large amount of axial compensation, and is suitable for long-distance thermal pipelines.
Long life: The materials and design ensure that the compensator has a long service life and is suitable for long-term buried applications.
Free expansion and contraction: Under the protection of the guide sleeve and the housing, the bellows can be freely expanded and contracted to realize the compensation function.
Strong adaptability: Works in a variety of soil types and groundwater conditions.
Installation Requirements
Inspection and validation: Before installation, check the model, specification and pipe configuration of the compensator to ensure that it meets the design requirements.
Direction of media flow: For directional compensators, note that the direction of the inner sleeve should be consistent with the direction of media flow.
Pre-deformation: For compensators that need to be cold tightened, the auxiliary components used for pre-deformation should be removed after the pipeline is installed.
Avoid improper adjustments: It is strictly prohibited to use compensator deformation to adjust the installation error of the pipeline, so as not to affect the normal function.
Installation, fixation and guidance: Ensure that there are sufficient fixing points and guide brackets on both sides of the compensator to control the direction of movement of the pipe.
Insulation and backfill: Carry out heat insulation treatment, use sand to fill the surroundings of the pipe ditch, avoid hard objects directly contacting the compensator, and then cover the original soil.
Instructions for Use
Axial compensation: It is mainly used for axial compensation of directly buried pipelines, and the influence of pipeline sinking may not be considered.
Super flexural resistance: It has super bending resistance and is suitable for the application of directly buried pipeline.
Maintenance and Inspection
Periodic inspection: Check the operating status of the compensator regularly, including the integrity of the bellows, the effectiveness of the guide mechanism, etc.
Cleaning and preservation: Keep the surroundings of the compensator clean and perform regular anti-corrosion treatments, especially on the exposed parts.
Summary
Directly buried thermal pipeline compensator is the key component to ensure the long-term stable operation of directly buried thermal pipeline system. Proper installation and maintenance maximizes its effectiveness, reduces the maintenance costs of the plumbing system and extends the service life of the entire system. During the specific installation and use process, the manufacturer's guidance and relevant industry specifications should be strictly followed to ensure the performance and safety of the compensator.
