Grooved type flexible metal hose is a flexible connector designed to accommodate movement, vibrations, and thermal expansion in piping systems. It features grooved ends that allow for quick and secure connection to other grooved components using mechanical couplings. This type of hose is commonly used in systems where ease of installation and flexibility are essential.

1.Grooved Connections: The hose ends have machined grooves that enable secure attachment to pipes or equipment using grooved mechanical couplings. This connection method allows for quick assembly and disassembly without the need for welding or threading.
2.Flexibility: The hose’s flexible metal construction allows it to absorb vibrations, thermal expansion, and slight misalignments in the piping system, reducing stress on connected components.
3.Durable Materials: Typically made from stainless steel or other high-quality metals, grooved type flexible metal hoses offer excellent resistance to corrosion, high temperatures, and mechanical wear.
4.Versatility: These hoses are available in various sizes and pressure ratings, making them suitable for a wide range of applications, from low-pressure HVAC systems to high-pressure industrial processes.
Grooved type flexible metal hoses are used in various industries, including:
Fire Protection Systems: Used in sprinkler systems to provide a flexible connection that can accommodate building movement and thermal expansion.
HVAC Systems: Applied in heating, ventilation, and air conditioning systems to manage airflow and vibrations while allowing for easy installation and maintenance.
Industrial Piping: Employed in systems transporting steam, gases, and liquids where flexibility and ease of maintenance are essential.
Water Supply Systems: Utilized in pipelines to connect different sections or components, allowing for movement and vibration isolation.
Overall, grooved type flexible metal hoses are essential for systems requiring quick and flexible connections, providing reliability, ease of installation, and durability in a wide range of applications.
