Leading Flexible Hose & Expansion Joint Manufacturer & Supplier



A corrugated flexible metallic hose with close pitch omega shape annular corrugations, hydroformed from butt welded precision tube. The depth and shape of the corrugations provides excellent flexibility and cycle life.
One or two layers of close weave metallic wire braid applied at the optimum angle is added to the outside of the hose to enhance the pressure capability of the hose. The hydroforming with water as the forming medium enables the corrugation to be formed from thicker material and allows for the preferable deeper corrugations. This method of forming is also less stressful on the material assisting in a longer service life.

Principal Applications
PARREX is ideal for the conveyance of liquids and gases in a wide range of temperatures from cyrogenic -200°C to over +500°C, however note as the temperature rises the pressure capability rating of the hose reduces.
The hose can be used with in-plant applications, to correct pipework misalignment or with moving machinery and equipment. The omega shape corrugations make this hose particularly suitable for high vibration applications. The hose being manufactured usually from stainless steel is suitable for a wide range of chemicals in corrosive situations.
