Parameters Of PVC Coated Metal Hose
Jun 09, 2026
The main components of the PVC-coated metal hose are made of austenitic stainless steel, ensuring excellent temperature and corrosion resistance. The operating temperature range of the PVC-coated metal hose is extremely wide, from -196 to 600℃. In actual use, the appropriate stainless steel grade is selected based on the corrosiveness of the pipeline medium to ensure the corrosion resistance of the PVC-coated metal hose.
Applications of PVC-coated metal hoses: Suitable for applications requiring highly flexible conveying pipes, and for applications where vibration must be prevented. Suitable for steam, gas, air, heavy oil, petroleum, and chemical industries. For specific selection, refer to the hose material and corrosion resistance parameter table, as well as the nominal diameter and pressure table for corrugated PVC-coated metal hoses. When using, please refer to the correct usage and installation methods for PVC-coated metal hoses and the optimal length for settlement compensation. Five key factors for selecting PVC-coated metal hoses (stainless steel PVC-coated metal hoses):
Dimensions: Nominal diameter of the PVC-coated metal hose, connector type and size. Length of the PVC-coated metal hose.
Pressure: Actual working pressure of the PVC-coated metal hose, selected nominal pressure PN / working pressure P.
Medium: The chemical properties of the medium transported in the PVC-coated metal hose. Based on the corrosion resistance table, the material of each component of the PVC-coated metal hose is determined.
Temperature: The operating temperature and range of the medium inside the PVC-coated metal hose; the ambient temperature during operation. At high temperatures, a temperature correction factor must be used to determine the maximum allowable pressure at the operating temperature to select the correct pressure rating.
Conditions: Based on the condition of the PVC-coated metal hose during use, and referring to the correct installation method, the length of the PVC-coated metal hose under various motion conditions and the minimum bending radius, etc., should be correctly selected to ensure proper installation. PVC-coated metal hose material: SUS301/SUS304; inner diameter 4mm-10mm, polished.
