FLEXIBLE METAL HOSE

SMGI Flexible Metal Hose and End Connections

  • High-pressure corrosion resistant all-metal hose.
  • 316L stainless steel annular convoluted core.
  • Size range of 1/4 through 2 in. and working pressures to 6000 psig, 413 bar (FX Series) and 3100 psig, 213 bar (FM Series)
  • Double braid layers of 321 stainless steel promotes hose pressure containment (FX Series)
  • End connections welded in accordance with ASME Boiler and Pressure Vessel Code Section IX
  • Commonly used in high-temperature vacuum and high or medium-pressure corrosive environments or where permeation is undesirable.
  • Standard and custom assemblies available.
  • Options include hose covers, hose tags, and additional helium leak testing.

Testing
Every SMGI hose assembly is inboard helium leak tested to a maximum leak rate of 1 × 10–5 std cm3/s. For additional testing, please inquire your requirements!

Cleaning and Packaging
SMGI hose components are cleaned in accordance with our standard. Each hose is bagged individually and boxed; longer hoses are coiled, bagged, and boxed.

Considerations for Selecting a Hose Assembly Solution
Temperature Identify the minimum and maximum temperatures the hose assembly will be exposed to with regard to the system media and the environment.
Pressure Identify the minimum and maximum pressures (or vacuum) within and outside the hose assembly.
Material Identify the system media and the environment to which the hose assembly will be exposed.
This will help determinethe materials of construction best suited to the applicationdemands and whether the hose requires a static dissipativecore.
Movement Confirm whether the hose assembly will be installedin dynamic applications as this will require differentconsiderations than a static application.
Length Determine the most likely route for installation of the hose, and use this to identify length requirements.
Cleanliness Identify the need for cleanliness. Ease of cleaning the internal surfaces of the hose, as well as maintaining outside cleanliness may be of concern.
End Connection Identify the type of end connections which are most compatible with the system requirements. End connections differ with regard to materials of construction and pressure ratings.
Orientation Clarify space constraint concerns. Hose assemblies with elbows and union ball joints may help resolve space constraint issues.
Desired Flow Consider desired flow. Hose connection size, core tube construction, and routed installation may impact flow.
Drainability Consider core construction as this will impact drainability. Test ReportsIdentify the need for documentation in the form of testreports.
Special Marking Discuss special marking requirements; there are different options available to readily identify hose assemblies.
Documentation and
Regulatory Requirements
Identify the need for special regulatory approvals or documentation.
Additional Protection
and Covers
Identify whether covers are necessary for additional protection of the hose assemblies or surrounding systems.
