The importance of PVC steel wire hose to industry
Braided hose can be divided into single head pipe, braided hose and shower hose. As for the production process, it can be low, medium and high grades. Low-end braided hoses adopt aluminum wire, iron nut, zinc alloy inner core and rubber inner tube. This kind of hose is cheap, but they are of the lowest grade. Besides, there will be problems such as water leakage and oxidation. While mid-range braided hoses mainly adopt 304 steel wire, EPDM and all-copper parts. And the service life is more than 5 years. High-end braided hose has special uses. For example, water purifier hose. In general, this requires 304 stainless steel wire, food grade silicone tube, silicone gaskets, etc.
Several types of braided hose
The single-head tube is mainly for kitchen and bathroom hardware such as faucets and sinks. Its name comes from the fact that one end has external teeth. The single-head tube requires 304 stainless steel wire and EPDM inner tube. While the parts are all copper. Shower hoses have 201 and 304 stainless steel wire, EPDM tube and all-copper fittings. Of course, they also include high-end all-copper and gold-plated types. While these are the higher-end braided hoses
Braided hose works on drinking water or sanitary equipment. While people directly drink the water from the hose. Therefore, the inner tube in contact with the water source is very critical. It should be food grade. Besides, the nation has strict standard for this. In Europe, Germany has put forward higher requirements for braided pipe. It requires the inner pipe to undergo a microbial toxicity W270 test. Then the original PVC and EPDM can no longer meet the standard. The latest inner tube materials in the European market are mainly silicone tubes or PEX-B tubes. But the cost of silicone tubes is too high. Thus PEX-B tubes is the future trend in the European market.
