In order to meet people's needs, rubber water hoses have been introduced on the market. Rubber water hoses are not only environmentally friendly, but also have the advantages of UV resistance, ozone resistance, high and low temperature resistance.
Rubber water hose inspection standards:
1, Rubber water hose size measurement: inner diameter, outer diameter, enhanced outer diameter, wall thickness, concentricity, inner and outer layer thickness, component internal diameter, the new national standard and ISO increased the length and measuring point mark, provided for the pipeless fitting and has a variety of tube length measurement methods.
2, Water hose pressure test: test hose and assembly under verification pressure continuous 30s-60s whether leakage, deformation and damage. Pressure deformation test: maintain s1 for 1 minute at specified pressure (working pressure verification pressure or other pressure below the verification pressure), measure the length and outer diameter of the hose and to twist angle and bend.
3, Water hose blasting pressure test: to determine the pressure of the hose burst at the prescribed speed of boost. Leak test: Save 5min at 70% static pressure of the smaller blasting pressure and repeat to check for leaks or damage. Since tests tend to be watered, the blasting pressure and leakage pressure measured at room temperature may be slightly lower than the viscosity of the liquid actually used.
Rubber Water Hose are mainly used in industry, mining, civilian transportation and attractliquid, gas and so on.
