hose, specially designed for refrigerating applications

摘要

The invention concerns a hose having at least the following layers in this order: an inner layer (A4),which is made of thermoplastic material or thermoplastic elastomeric material; an inner layer (A4) mounted on the inner layer (A5),made of elastomeric material; at least one strength support layer (B, B1, B2),where the strength carrier is positioned at an angle smaller than the neutral angle of 54,7,and, where applicable, an outer layer (C),made of polymer material.The hose is particularly suitable for use as a pressure carrier for coolant pipes, especially CO2, for use as a pressure carrier for wave pipes.
