Metal Hose Price

Price Factors&Determinants

The price of a metal hose is not a single standard figure but is determined by a combination of engineering specifications,material costs,and manufacturing complexity.Understanding these factors is essential for accurate budgeting and specification.

Primary Cost Drivers

Material Composition&Grade:

Base Material:A hose made of standard 304 stainless steel is the most economical.Upgrading to 316/L stainless steel adds a premium for enhanced corrosion resistance.High-performance alloys like Inconel®,Monel®,or Titanium significantly increase cost.

Braiding:An unbraided hose is the least expensive.Adding a single braid increases cost for pressure capability and protection.A double braid commands a higher price for high-pressure/high-vibration service.

Special Finishes:Electropolished(EP)interiors for ultra-high-purity applications add substantial cost due to specialized processing.

Hose Dimensions&Construction:

Diameter(ID):Larger diameters require more material and are more costly.

Length:Price typically increases with length,though there are standard cut lengths.

Corrugation Type:Annular corrugated hoses(for pressure)have a different cost structure than helical corrugated hoses(for large movement).

End Fittings&Assembly:

Fitting Material:Stainless steel fittings are standard;exotic materials increase cost.

Fitting Type&Complexity:Simple male NPT ends are economical.Flanges(ANSI,DIN)are more expensive due to machining.Specialized clean fittings(VCR®,ISO-KF)are premium items.

Attachment Method:Permanently swaged/captive fittings are standard.Reusable fittings may have a higher initial hose assembly cost but can offer savings on future replacements.Welded fittings for critical service add labor and precision cost.

Certifications&Testing:

Hoses requiring third-party certifications(e.g.,for marine,aerospace,food grade),traceability documentation,or additional testing(e.g.,helium leak test,extreme pressure burst test)will carry a higher price.
