The metal composite hose is made of stainless steel and carbon structural steel. It is a new material that is non-destructively pressure-compressed. It has both stainless steel corrosion resistance and excellent appearance, as well as good bending strength and impact resistance of carbon steel. Sex. In line with national energy conservation and popularization principles. The stainless steel composite pipe was officially promulgated in the national standard GB/T18704-2002 in 2002. It has a set of strict and standardized management from the aspects of material quality selection and inspection, due to its beautiful appearance and low price.
The tube body is composed of a multi-layer functional polymer film and a synthetic fiber fabric reinforcing layer, and the inner and outer two-layer spiral metal wire is wound and fastened inside the spiral steel wire: according to the characteristics of the hose conveying medium, the stainless steel hot-dip galvanized steel aluminum alloy polypropylene or Teflon coating is selected. Steel wire spiral wire: basic selection of hot-dip galvanized steel wire or stainless steel wire
Liner: Provides chemical resistance to chemical and liquid barriers. It plays a key role in hose quality. It is usually modified according to the characteristics of the transport medium. Modified Teflon (polytetrafluoroethylene PTFE) nylon cross-linked polymer Dozens of functional materials such as ethylene, through the proprietary technology, make the hose have excellent fatigue resistance, chemical liquid corrosion resistance, chemical liquid permeability and safety performance close to zero.
Metal composite hoses are now widely used in bridge guardrails, decoration, vehicle accessories, conveyor rollers, textile machinery accessories and other fields.
