| Copely Medical Reinforced PVC Gas Hose BRN Series
General Description
In the medical field, Copely innovation has established a standard for medical gas hose now recognised by the industry. The development of new and advanced thermo-plastic materials with co-extrusion possibilities allow the designer more freedom to secure a thermo-plastic solution rather than traditional materials.
Braiding and Braid Angles
The angle of application of the reinforcing fibres, irrespective of the denier, is critical in the achievement of a ‘balanced’ pressure hose. Copely manufacture hose with a target angle of 54º 44’ (54.73º) being the optimum angle. Variations to the angle are generally for economic reasons, but major variations will have a marked effect on the performance and longevity of the product.
The hoses conform to BS 5682: 1984 Medical Gas Pipeline Services, ISO 5359: 1989 and BS 2050: 1978 Electrical Conductivity.
Each coil is 100% tested prior to despatch for: anti-static properties, flow rate under applied external pressure and flow rate without external pressure.
