Bypass straight pipe pressure balance compensator is a device used to compensate the axial displacement in pipeline system caused by temperature difference, settlement, vibration and other factors. Mainly consists of two corrugated elements with identical geometric parameters and two adjacent pipelines, equipment connected to the receiver (or flange) and the head. By the internal pressure of the working wave and an external pressure of the balance wave composition, can effectively absorb the axial displacement of the pipeline and balance the internal pressure of the bellows thrust.

The by-pass straight pipe pressure balance compensator is widely used in the pipeline system of petroleum, chemical, electric power, metallurgy and other industrial fields to compensate the axial displacement of pipeline and protect the stability of pipeline system.

Advantages

(1) Absorption of internal pressure thrust: the by-pass straight pipe pressure balance compensator has the ability to absorb internal pressure thrust, can self-balance the internal pressure thrust, reducing the need for fixed supports.

(2) Superior self-balancing: compared with other types of compensators, the by-pass straight pipe pressure balance compensator has superior self-balancing, which can better cope with the pressure changes inside the pipeline.

(3) Small stiffness and good orientation: the compensator has small stiffness and good orientation, which can better adapt to the displacement changes of the pipeline.

(4) Small external dimensions: the external dimensions of the by-pass straight pipe pressure balance compensator are small and economical, suitable for use in occasions with limited space.

(5) Installation without directional requirements: the installation of the compensator has no directional requirements, the installation is more simple. ‌
