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.

 

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.
