Product Description

Hinged corrugated compensator also called as expansion joint , compensator, who is composed of corrugation (work body, a elastic component), end tube, bracket, flange, guide tube and other components.

The main advantage of hinged corrugated compensator is compact size, easy for installation. Its hinge plate has huge rigidity and intensity which can compensate displacement because of thermal expansion in irregular configuration of complex pipeline in practice, in which other corrugated compensator cannot. Since the hinge structure of this corrugated compensator can transfer load, and force exerted on fixed trestle from its pipeline system is small, supporting point of such pipeline system could be set on anywhere not hamper system's activity. Based on this, it leaves great freedom to the design of pipeline system.

Double hinged corrugated compensator is composed of two or three corrugations, connecting long middle tube, hinge pin (cross pin), hinge plate, vertical plate and other components. Double hinged type corrugated compensator is an augmented product of corrugated compensator. Its primary characteristic is that it can be applied in long junction interval and big compensate dosage in pipeline, while ordinary corrugated compensator cannot satisfy such need. It surely can connect the pipeline to use single corrugated compensator increasing its corrugations, but there is an inevitable defect. The compensator will be damaged by tensile and axial force in operation pipeline day by day when it is too long. Meanwhile corrugation may be pulled slantingly which would have bad influence on its normal operation.

Double hinged corrugated compensator can be divided into complanate double hinged type corrugated compensator and versatile double hinged type corrugated compensator.

Complanate double hinged type corrugated compensator can be referred to as double hinged corrugated compensator, which is composed of two single corrugated compensator, middle tube, hinge pin, hinge plate, vertical plate and other components. It can absorb the unitary planar lateral displacement, and its hinge plate and hinge pin can absorb the internal pressure thrust. It is often applied in L or planar Z shaped pipeline.

Versatile double hinged type corrugated compensator can be referred to as versatile corrugated compensator, which is composed of two single corrugated compensator, middle tube, cross hinge pin, hinge plate, vertical plate and other components. It can absorb the arbitrary planar lateral displacement, and its hinge plate and cross hinge pin can absorb the internal pressure thrust. It is often applied in vertical Z shaped pipeline.
