When you get ready to order hoses from Swagelok Northern California, use the S.T.A.M.P.E.D. method to make sure you are getting what you need. The letters stand for Size, Temperature, Application, Material, Pressure, End Connection and Delivery.
Let's go through the list:
- Size: Swagelok offers hose in nominal diameters of 1/8 inch to 2 inches. Not all sizes are available in all types of hose. Size also is a consideration when you have concerns about space constraints. Hose assemblies with elbows and union ball joints may help resolve those issues.
- Temperature: Identify the minimum and maximum temperatures the hose assembly will be exposed to with regard to the system media and the environment. Different hose materials operate best within different temperature ranges. Metal hose is the choice for temperatures from minus 325 degrees (Fahrenheit) to plus 850 degrees. Fluoropolymer Hose has a narrower range, from minus 65 to plus 450 degrees. Nylon hose has an even narrower range, minus 40 to plus 200.
- Application: If the hose is expected to flex or otherwise change position while in use, that's called a Dynamic Application. If the hose is to remain stationary and not move in any plane, that's called a Static Application.
- Material: Identify the system media and the environment to which the hose assembly will be exposed. This will help determine the materials of construction best suited to the application demands and whether the hose requires a static dissipative core.
- Pressure: Identify the minimum and maximum pressures (or vacuum) within and outside the hose assembly.
- End Connection: Identify which type of end connection is most compatible with the system requirements. End connections differ with regard to materials of construction and pressure ratings.
- Delivery: How fast do you need it? Swagelok Northern California stocks a range of high-quality hose and tubing products locally, and can custom-fabricate hoses at our Fremont center.
