Classification of braided hose
- Oct 25, 2017 -

Braided hose in general according to the above functions can be divided into a single head tube, woven tube, shower tube. Braided hose can be divided into three grades: low, medium and high according to the production process. The lower braided hose is made of aluminum wire, iron nut, zinc alloy inner core and rubber inner tube. This configuration of the product has a certain price advantage, but the lowest grade, it is prone to leakage, oxidation and other issues. The medium knitting pipe is mainly made up of 304 steel wire, EPDM material and all copper fittings. The application period is generally more than 5 years. High end braided hose has specific uses, such as water purifier braided hose. General requirements in the mid-range configuration, configuration of common stainless steel wire 304, food grade silicone inner tube, food grade PEX-B inner tube, 58-3 all copper fittings, silica gel gasket, etc..

The braided hose can be divided into single head tube, braided pipe and shower tube (shower hose) according to the use. The first single tube is mainly used for leading, vegetable washing basin and other kitchen hardware, her name is derived from one end with outer teeth, also known as the pole, single head tube weaving requirements of 304 stainless steel wire, EPDM pipe fittings, etc., for the whole of the copper tube is woven stainless steel and alloy wire (wire) points, also divided into upper and lower. Shower tubes are generally woven with 201 and 304 stainless steel, EPDM inner tubes, all copper fittings. The shower pipe in general do 58-3 copper fittings, EPDM tube, 201 and 304 stainless steel woven, of course, including high-end copper braid, stainless steel and gold products, these are high-end products woven hose.

The implementation of the standard tube is GB/T23448-2009 or JC886-2001, the braided tube is mainly used in sanitary equipment or drinking water equipment connected to water supply, water through pipes directly in contact with the skin or by direct drinking. So the inner tube material that contacts the water source is critical. The existing GB or the Ministry of construction standards require the inner pipe material to meet the "GBT17219-1998 drinking water distribution equipment and protective materials safety evaluation standards", so as to ensure that the water source is not contaminated. In Europe, Germany for weaving pipeline put forward higher requirements, especially in connection with drinking water braided tube, microbial toxicity test tube W270 requirements, in this case, the original PVC, EPDM and other raw materials have been unable to meet the requirements. European market is now widely used, the latest internal tube material is mainly silicon rubber tube or PEX-B tube, because the silicone rubber tube cost is too high, so now the European market PEX-B pipe will be the future trend. Of course, including Europe and the United States and other developed countries
