Metal Flexible Joints

Metal flexible joints, also known as metal hoses or corrugated metal pipes, are designed to provide flexibility and absorb movement in piping systems. One specific type is the loose flange metal hose, which offers unique benefits in various industrial applications.

1. Loose Flange Metal Hose

Structure:

The loose flange metal hose consists of a welded straight pipe, which is attached to a loose flange on one or both ends. A steel wire mesh sleeve is wrapped around the corrugated metal bellows to provide additional strength and protection. The loose flange allows for easy installation and disassembly, making it a versatile choice for many piping systems.

Features:

Good Seismic Performance: The flexible nature of the metal bellows allows the hose to absorb vibrations and movements, making it particularly suitable for seismic-prone areas.
Strong Protective Mesh Sleeve: The steel wire mesh sleeve provides additional reinforcement and protection against external impacts or abrasion.
Nominal Diameter:

The loose flange metal hose is available in a wide range of nominal diameters, typically ranging from DN150 (approximately 6 inches) to DN2000 (approximately 80 inches), allowing for flexibility in choosing the appropriate size for different applications.

Materials:

The loose flange metal hose is constructed using high-quality materials to ensure durability and performance.

(1) Loose Flange: The loose flange can be made from carbon steel or stainless steel, depending on the specific application requirements. Carbon steel is a cost-effective choice for general-purpose applications, while stainless steel offers superior corrosion resistance for more demanding environments.
(2) Pipe: The welded straight pipe is also available in carbon steel or stainless steel. The choice of material depends on the intended use and the operating conditions of the piping system.
(3) Metal Bellows: The corrugated metal bellows, which provide the flexibility of the hose, are typically made from SUS304 or SUS316 stainless steel. These materials offer excellent corrosion resistance and mechanical properties.
(4) Pressing Ring: The pressing ring, which secures the loose flange to the pipe, is also made from SUS304 or SUS316 stainless steel. This ensures a secure and reliable connection between the components.
(5) Steel Wire Mesh Sleeve: The steel wire mesh sleeve that surrounds the metal bellows is typically made from stainless steel. It provides reinforcement and protection against external impacts or abrasion, extending the service life of the hose.
Overall, the loose flange metal hose is a versatile and reliable choice for piping systems that require flexibility and the ability to absorb movement. Its unique structure and materials make it suitable for a wide range of applications, including industrial, commercial, and residential piping systems.
