What‘s the usual implementation standard for braided pipes

The usual implementation standard for braided pipes is GB/T23448-2009 or JC886-2001. Because braided pipes are mainly used in the water supply connection of sanitary equipment or drinking water equipment, the water passes through the pipe directly in contact with human skin or is directly drunk. Therefore, the material of the inner tube in contact with the water source is very critical. The existing national standards or the standards of the Ministry of Construction require that the inner pipe materials must meet the "GBT17219-1998 Safety Evaluation Standard for Drinking Water Transmission and Distribution Equipment and Protective Materials" in order to ensure that the water source is not polluted. In Europe, Germany puts forward higher requirements for braided pipes, especially braided pipes connected to drinking water, requiring the inner pipe to be tested for microbial toxicity W270. Under this requirement, the original PVC, EPDM and other raw materials can no longer meet the requirements. . The latest inner tube materials commonly used in the European market are mainly silicone tubes or PEX-B tubes. Due to the high cost of silicone tubes, PEX-B tubes in the European market will be the future trend. Of course, other developed countries such as Europe and the United States are included.
