Hydroulic / Rubber Hose

Rubber hose assemblies are fabricated by cutting the bulk hose to length and attaching the hose ends (sometimes called hose fittings) to either end by crimping, swaging or other methods (for field attachable and barb hose ends).

Reasons to use rubber hose assemblies:

Generally easier to route a hose assembly over, under, around, or through a series of obstacles
Generally easier to replace in the field
Generally more widely available than either hard line or metal flex assembly
Availability of wide range of hose types for wide range of applications
Wide range of pressure ratings up to 10,000 psi
Great resistance to vibration when used with proper fittings

Reasons to consider alternative solutions:

Rubber hoses cannot withstand as much pressure and external forces as hard lines can.
Rubber hoses are not as space efficient as hard lines.
Rubber hose assemblies age and need to be periodically replaced.

Hose Assy Metalic

Hose assemblies are fabricated by welding the stem and butt of the hose ends together and welding the fittings onto the metal flex hose
Reasons to choose metal flex assemblies

    Need for the strength of a steel tube with the flexibly of a hose.
    Great heat resistance
    High pressure rating

Reasons to consider alternative solutions:

    Fabrication of metal flex hose assemblies involves welding the seam and butt as well as a fitting attachment. If not welded correctly, a leak path can be created.
    Metal flex assemblies are not readily available in most markets

A combination of the hard lines and flexible hoses can also be a great solution to unique challenges. It would be the most desirable combination if vibration is severe

Rubber Expansion Joints

Rubber expansion joints / compensators are used as flexible connectors within pipe systems.

ERV’s are single sphere type rubber expansion joints within swivelling metal flanges. The high quality bellows are produced in a mold. Starting forty years ago, construction and length of ERV expansion joints have become recognized standards worldwide.
