General descrition

 

Ripple compensator is a compensation element, effective use of bellows telescopic body deformation, dimensional change in absorption pipeline, pipe, thermal expansion and contraction caused by the container, or compensation pipeline, conduit, vessel axial, transverse and angular displacement. Ripple compensator is mainly used for noise reduction and vibration reduction. It is widely used in modern industry.

 

 

Main technical parameters and schematic diagram

 

(1) nominal diameter of pipeline :DN25 -- 1000mm

(2) applicable nominal pressure range :PN≤2.5MPa

(3) applicable working temperature :t≤350℃

(4) scale

(5) selection of expansion joint

When selecting the compensator, the nominal diameter DN shall prevail. The outer diameter of the designed pipeline shall be the same as the inner and outer diameters in the parameter list, with the allowable error ≤3mm.

The model of the selector compensator should be indicated in the following example.

 

Note: material code: bx represents all stainless steel 1Cr18N19Ti, T represents carbon steel q235-a, BXB represents semi-stainless steel (expansion tube 1Crl8N19Ti)

Function of metal expansion joint

 

1. compensating the axial, transverse and angular thermal deformations of the absorption duct.
2. to facilitate the installation and disassembly of valves and pipes.
3. to reduce the impact of equipment vibration on the pipeline.

 

Classification of metal expansion joint

 

Metal bellows compensator, axial, horizontal, angular type of three types of tens of thousands of specifications, different types and specifications of products, according to customer care settings and the amount of compensation and other requirements of the design and production.
