Rectangle Double Bellow Expansion Joint

Rectangle Double Bellow Expansion Joint


Rectangular double-wave expansion joint is a device used to compensate the thermal expansion and contraction phenomenon caused by temperature change of pipeline, which is usually arranged immediately beside the fixed bracket, and then immediately after the two guiding brackets to prevent its axial instability. 

Overview

Rectangular double-wave expansion joint is a device used to compensate the thermal expansion and contraction phenomenon caused by temperature change of pipeline, which is usually arranged immediately beside the fixed bracket, and then immediately after the two guiding brackets to prevent its axial instability. This arrangement can effectively reduce the number of brackets and lower the arrangement difficulties caused by terrain restrictions. To be applied in the boiler flue gas piping of power plants and steel mills, it can also be used in similar flue gas connection piping of metallurgy and chemical industry. Rectangular double-wave expansion joints can effectively reduce the vibration of the host machine, absorb the vibration of the pipeline, reduce the noise of the pipeline, protect the equipment, and prolong the service life of the pipeline through the characteristics of its elastic compensation element.

Advantages:

Good expansion and contraction: rectangular double-wave expansion joint can effectively absorb the size change of pipeline or equipment, reduce the stress, so as to extend the service life of the equipment.

High pressure resistance: Because it is made of metal material, rectangular double-wave expansion joint has high pressure resistance strength and can withstand high pressure.

High reliability: its simple structure, reasonable design, reliable operation, can ensure the normal operation of pipeline or equipment.

Convenient maintenance: simple structure, easy to maintain and replace.

Free expansion and contraction: Rectangular double-wave expansion joints can freely expand and contract in work, belonging to a kind of elastic compensation element, which can effectively reduce the vibration of the host, absorb the vibration of the pipeline, reduce the noise of the pipeline, protect the equipment, and prolong the service life of the pipeline.

Corrosion-resistant, high temperature resistant: made of high-quality stainless steel material, with good corrosion resistance and high temperature resistance, to ensure the long-term stable operation of the compensator in harsh environments.

Strong applicability: compact structure, reliable work, low cost, suitable for a variety of pipelines and equipment, such as steam piping, hot water piping, flue, etc..‌
