Piping Circular Braided Metal Flexible Hose

This product refers to a specific category of flexible connectors used in piping systems, defined by its round cross-section, metallic construction, and ability to absorb movement. A core standard governing such products is ASTM F1120, which establishes minimum requirements for the design and manufacture of circular metallic bellows-type expansion joints for absorbing thermal expansion or contraction in pipelines.

Core Structure & Design:
The key flexible element is a circular metallic bellows, typically made from stainless steel or other alloys, designed to deform elastically. To manage pressure and movement, the assembly often includes **tie rods or limit rods** to control expansion and absorb pressure thrust, and may feature internal liners for flow protection and enhanced stability. The ends are equipped with **circular flanges** (round head code) for standardized bolted connection to the piping system.

Primary Functions:
It is engineered to compensate for axial, lateral, and angular movements in pipelines caused by thermal changes, vibration, or settlement. By absorbing these displacements, it protects equipment like pumps and turbines from stress, reduces noise and vibration transmission, and maintains system integrity under cyclic loading conditions.

Typical Applications:
This type of joint is critical in demanding industrial applications, including chemical and petrochemical plants, power generation, district heating systems, and marine engineering, where durability, pressure resistance, and compensation for large multi-directional movements are required.
