Buried type metal expansion joint is a kind of corrugated compensator, which is an equipment to compensate dimensional change caused by thermal expansion or mechanical vibration of pipeline/conduit/vessel through corrugated compensator's elastic component.
DESCRIPTION

Buried type metal expansion joint, who could be called axial externally pressurized expansion joint/bellows, is composed of internal tube, external tube, corrugation-the affiliated pressure bearing component, end links & other components required. It is a kind of corrugated compensator, which is an equipment to compensate dimensional change caused by thermal expansion or mechanical vibration of pipeline/conduit/vessel through corrugated compensator's elastic component.


Based on above, it can decrease the deforming stress exerted on pipeline and increase service life of pipeline. Buried type metal expansion joint has three patterns of structure, simplex, complex and bidirectional type. Corrugations in all of the three are equipped within external tube and its protection. It can be used together with guide cylinder (lining sleeve), draw rod, gas vent or drainage exit in practice.

DETAILS
Buried Type Metal Expansion Joint

Bellows Material: Bellows is made from high quality stainless steel, strong pressure resistance ability, excellent low temperature resistance and shock resistance capacity.

Buried Type Metal Expansion Joint

Large Tie Rods: Two connection methods: welding connection and flange connection, which all make compensator in balanced stress, not easy to deform.

Buried Type Metal Expansion Joint

Small Tie Rods: During transportation, limit the displacement of bellows and protect the bellows.
