In order to meet people's needs, rubber water hose pipe is introduced on the market. Rubber water pipes are not only very environmentally friendly but also have the advantages of ultraviolet resistance, ozone resistance, high and low-temperature resistance. At present, it has been widely used in our daily life. How much is a rubber hose pipe per meter? Which is better, rubber pipe or PPR pipe? The following article will share these issues with you, looking forward to helping those who need it.
There are many brands and varieties of Rubber Hose on the market. Rubber Hoseof different materials is suitable for use in different places. Rubber Hose has different brands and materials, and its price is also different. Usually, the price of rubber hose varies from several yuan to more than ten yuan according to the grade. It is precise because of the big price difference that we must pay attention to the identification when choosing and purchasingrubber hose.
At present, there is a great demand for rubber water hose pipe in the market. Some illegal manufacturers will start on raw materials or processing technology in order to make huge profits. What is the inspection standard for rubber water pipes? Xiaobian suggests that you should pay attention to the following points when choosing and purchasing:
1. Rubber pipe size measurement: inner diameter, outer diameter, reinforcement layer outer diameter, wall thickness, concentricity, inner and outer rubber thickness, assembly inner diameter. The new national standard and ISO increased the length and measurement point marks and provided the measurement method of rubber pipe length without pipe joints and various pipe joints.
2. Hydraulic test and validation pressure test: Check whether the hose and assemblies will leak, deform and destroy under the validation pressure lasting for the 30s-60s. Pressure Deformation Test: Hold for 1 minute under specified pressure (working pressure verification pressure or other pressure below verification pressure), measure the length and outer diameter of the hose, twist angle and bending.
3. Blasting pressure test: Measure the pressure when the rubber hose bursts at the prescribed boosting speed. Leakage test: Preserve for 5 minutes under 70% static pressure of smaller blasting pressure, and check for leakage or damage repeatedly. Because water is often used in the test, the explosion pressure and leakage pressure measured at room temperature may be slightly lower than the actual viscosity of the liquid used.
Rubber pipe is good, but it is not suitable for home decoration. It is mainly used for industrial, mining, civil transportation and attracting liquids, gases and so on. At present, the best material for household water pipes is PPR pipes, which are green and environmentally friendly, stable in performance, heat and heat preservation, corrosion resistance, smooth in-wall and non-scaling, safe and reliable in the piping system, and impermeable, and can be used for up to 50 years.
