Pacific Hoseflex Stainless Steel Metallic Hose
The stainless steel corrugated hose is especially designed to achieve several objectives in pipe work design. These include, absorption or vibration, operate under vacuum, handle temperature extremes, suppress rigid pipe noise transmitted, accommodate reciprocating and flexing movement, operate effectively under high pressures and adjust or correct for misalignment.
Stainless steel corrugated hose is a general purpose industrial hose and is available in different grades of stainless steel including 304, 316, 321 and Monel.
The corrugated hose is manufactured from a cylindrical, thin walled tube formed from rolled strip and welded at the seam. Impressed into this tube is a corrugated annular profile. Annular corrugation means each convolution is perpendicular to the centre line of the hose giving a distinct advantage of movement with each corrugation being relatively independent of movement from each other. When the corrugations are closely spaced, the hose is referred to as 'closed pitch' hose. Conversely, when the corrugations are more widely spaced, the hose is referred to as 'open pitch'.
When needing greater flexibility Omega style hose is ideal. It has a higher flexing cycle life because of the increase in the number of convolutions per metre without thinning the wall of the hose. The corrugations have the tendency to spring back to their original position when the displacement forces are removed.
Contingent upon the extremes of temperature; hot or cold metal is a positive choice as it can withstand temperature extremes.
Metal hose is an excellent option as it effectively controls exposure to a wide range of chemicals – both internal and external.
Metal hose is not subject to permeation whereas non metal hose can allow permeation through the hose wall material. Pacific Hoseflex has Australian Gas Approved (AGA) certified hose to assure customers of compliance.
Generally speaking, metal hoses do not disintegrate rapidly causing any major failure. Warning signs are evident that leaks are present and the medium escapes gradually. Non-metallic hoses can be prone to sudden failure.
External Abrasion and Over bending
A range of options exist to prevent these occurrences; including external braid, spring guards, rubber and PVC covers and protective sleeves.
Heat and fire
Our metal hoses maintain form and structure up to 700°C.
Where other hose products will collapse, our metal hose will maintain shape under full vacuum.
Fittings / Flanges
We can adapt virtually any fittings and flanges to a metal hose - other hose products require special and significant variances. We specialise in providing flexible options.
