Product Classification Of Industrial Hose
Product classification of industrial hose
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. "Shower tubes are usually made of 58-3 copper fittings, EPDM inner tubes, 201 and 304 stainless steel woven, of course, including high-end all copper knitting, and stainless steel gold-plated products, these are woven hose in high-end products.".
The commonly used standard for woven pipes is GB/T23448-2009 or JC886-2001, because the braided pipe is mainly used in the water supply connection of sanitary equipment or drinking water equipment, and the water is directly contacted with human skin or directly drinkable after passing through the pipeline. 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 put forward higher requirements for braided pipes, especially the braided pipes connected with drinking water, requiring the microbial toxicity test of W270 in the inner pipe. Under this requirement, the original PVC, EPDM and other raw materials can not 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
