Axial type Hinged expansion joint with welding ends ISO 9001 Certification
Product description
The hinge expansion joint is also called a flat hinge corrugated expansion joint, and is composed of a pair of hinges connected to a pipe, a corrugated pipe and a pipe.It can only absorb the angular displacement of a single plane. When absorbing the displacement, two or three angular expansion joints should be used in combination.The hinge of the expansion joint has the ability to withstand internal pressure thrust.The hinge expansion energy-saving absorbs the angular displacement of any plane. When the displacement can be absorbed often, it should be used in combination of two or three. It is mainly used for the powder feed pipe of the boiler in the power plant.Thermal displacement.The hinge expansion joint is mainly used for the powder feed pipe of the boiler in the power plant, which absorbs the downward thermal expansion of the boiler hearth and the lateral expansion of the hearth and the thermal displacement of the powder feed pipe.
Installation Attention
1. The small tie rod on the expansion joint is used for installation and transportation adjustment, and cannot be used as bearing part. After the product is installed on the pipeline, the small tie rod must be removed before it can be put into operation.
2. When the expansion joint Angle deformation is required to be large or the system pressure is high, it is recommended that the product should be cooled during installation. The first is 50% or 0% cooling.
It can compensate the angular displacement of the arbitrary plane
The compensatory dosage of angular displacement in sample is the max compensatory dosage allowed in single plane.
