Braided hose generally according to the above functions can be divided into single head tube, braided tube, shower tube. Braided hose in accordance with the production process can be divided into low, medium and high third. Low braided hose in the material used on the relatively low-end wire diameter fine aluminum wire, iron nut, zinc alloy 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. Mid-range braided tube mainly to 304 wire, EPDM material, copper-based accessories. Applicable period is generally more than 5 years. High-end braided hose has a specific use, such as water heater braided hose. General requirements in the mid-range configuration first, configuration common 304 stainless steel wire, food-grade silicone tube, food grade PEX-B tube, 58-3 copper accessories, silicone gasket and so on.
Braided hoses can be divided into single head pipes, braided tubes, shower tubes (shower hoses) according to the intended use. Single head tube is mainly used for faucet, vegetables and other kitchen and toilet hardware, her name from one end of the external teeth, also known as rods, single-head pipe in the requirements of 304 stainless steel wire, EPDM inner tube, accessories for the copper Etc., braided tube is a stainless steel and alloy wire (aluminum wire) of the points, but also divided into upper and lower. Shower tube is generally 201 and 304 stainless steel weaving, EPDM inner tube, copper accessories. "Shower pipe is generally made of 58-3 copper fittings, EPDM inner tube, with 201 and 304 stainless steel braided, of course, including high-end all-copper braid, and stainless steel gold-plated products, these are relatively high-end braided hose product.
Braided tube is usually used in the implementation of the standard is GB / T23448-2009 or JC886-2001, because the braided pipe is mainly used in the health equipment or drinking water equipment, water connection, the water directly after the pipe with the human skin contact or be directly consumed. So the water pipe in contact with the inner tube material is critical. The existing national standard or the Ministry of Construction standards require internal pipe materials need to meet the "GBT17219-1998 drinking water transmission and distribution equipment and protective materials safety evaluation criteria" in order to ensure that water is not contaminated. In Europe, Germany has made higher requirements for weaving pipelines, especially braided tubes connected to drinking water, requiring microbiological toxicity of W270 in the inner tube. At this point, the original PVC, EPDM and other raw materials are no longer able to meet the requirements The European market is now widely used The latest tube material is mainly silicone tube or PEX-B tube, because the cost of silicone tube is too high, so now the European market PEX-B tube will serve as a future trend. Of course, including Europe and the United States and other developed countries.
