Composite Hoses

Composite hoses are grouped into two subgroups: fuel and chemical. In addition to spiral-reinforced polyethylene-polypropylene hoses, there are Trellflex models with polypropylene or PTFE film inner tubes and stainless or galvanized steel wire helices. These hoses are used for transferring petroleum products with aromatic content, biofuel, chemical waste and highly corrosive chemicals at working pressures of 10 to 15 bar.
