Double-Acting Rod-Type Bellows Expansion Joint

The double‑acting rod‑type bellows compensator is a metal expansion joint designed for complex industrial piping systems. It consists of two bellows compensation units and a rod‑based limit‑stop assembly, enabling it to absorb lateral displacements within its design range while allowing the system to accommodate limited axial misalignment. This type of compensator uses a rod‑based system to resist pressure thrust and control displacement direction, making it well suited for high‑temperature, high‑pressure applications and intricate piping layouts. It effectively reduces thermal stresses, minimizes equipment loads, and enhances the operational stability of industrial piping systems.

Product Overview

The double‑rod type bellows compensator is a metallic expansion joint designed for complex industrial piping systems. It consists of two bellows compensation units and a rod‑type limit‑stop assembly, enabling it to absorb lateral displacements within its design range while permitting limited axial coupled movements of the system.
This type of compensator uses a tie‑rod system to withstand axial thrust and control the direction of displacement, making it suitable for high‑temperature, high‑pressure applications and complex piping configurations. It effectively reduces thermal stresses, minimizes equipment loads, and enhances the operational stability of industrial piping systems.

Product Structure

The double‑acting rod‑type bellows compensator typically consists of the following components:
Dual-Corrugated Compensation Unit
Rod Limit System
Flange or welded nozzle
Intermediate connecting pipe
Flow guide tube (optional)
Limiting structure (optional)
The tie‑rod assembly is designed to withstand the system’s pressure thrust and to constrain the compensator’s operating displacement, thereby enhancing operational stability and safety under complex service conditions.

Scope of Application

Petrochemical Process Piping
Power plant boiler system
High-temperature steam pipeline
Metallurgical High-Temperature Gas System
Large-scale industrial pipeline network
Chemical reaction apparatus
Energy and Thermal Systems
Industrial Fluid Conveyance System
