Internal and external pressure balance compensatorThe NWP type is composed of an internal pressure working wave and an external pressure balancing wave, which can compensate for the axial displacement of the pipeline system and balance the internal pressure thrust. This structure can be used in high object position pipelines where fixed supports are not suitable.
Model: Produced by our factoryDN50-2000mm pressure rating: 0.1MPa~1.6MPa.
Connection method:1. Flange connection type 2, pipe connection type

Model compensation amount: according to customer needs
Internal and external pressure balanced bellows compensator, also known as internal and external pressure balanced pipeline expansion joint or metal bellows expansion joint. It has the ability to absorb internal pressure thrust, good guidance, low product stiffness, and small external dimensions. Axial compensation amount: According to the structural characteristics required by the user, the pipeline expansion joint is connected by an internal pressure expansion joint and an external pressure expansion joint. Compensation features: The pipeline expansion joint has a large compensation amount, no internal pressure thrust, and a small elastic reaction force.

Installation and usage precautions:
（1) During installation, the drain port should be facing downwards.
（2) After on-site installation, the tie rod must be removed.
（3) The flow direction of the medium during installation should be consistent with the flow direction mark of the pipeline expansion joint.
