BULK HOSE

Proper selection of metal hose type, its pressure rating and material is crucial to the proper life and function of the hose assembly for your application.
MDC corrugated hose is a high quality general purpose industrial hose. It is produced in T304 SS, T321 SS, T316L Bronze and Monel. Custom runs in Hasteloy, Titanium and other formable alloys.
Corrugated hose is manufactured from a cylindrical, thin walled tube formed from rolled strip and joined at the seam by butt welding.
Impressed into this tube is a corrugated annular profile. Annular corrugated hose has several advantages over helical hose. It is not subject to damaging torsional stress due to longitudinal expansion resulting from pressure rises.
Helical hose is formed in one continuous machine motion. It is generally less flexible than the annular hose, due to lower convolutions profile, but since less material is used in its fabrication and the manufacturing process is much faster, the cost is generally lower. MDC does not offer helical hose from stock.
When the corrugations are closely spaced, the hose is referred to as "standard pitch" hose. When the corrugations are more widely spaced, the hose is referred to as "open pitch" hose. All information in this section is relevant to standard pitch, annular corrugated hose. Data on open pitch hose is available upon request.
