Does a water pipe need to consider biocompatibility?

     The biocompatibility of water pipes is usually not the primary consideration because water usually does not come into direct contact with the human body unless it is used for special purposes such as in pharmaceuticals or laboratory applications. However, in some cases, biocompatibility is still an important consideration depending on the usage scenario of the water pipe and the purpose of the water being transported.

      Here are some situations where the biocompatibility of water pipes may need to be considered:

Medical water systems: In hospitals or medical facilities, where water is supplied to places that require high-purity water such as surgeries, wards, and laboratories, the biocompatibility of water pipes is crucial to ensure that the water supply is not contaminated or affects the health of patients or experiments.

    Drinking water systems: For drinking water systems, especially in some special uses such as food processing or the catering industry, it is also necessary to ensure that the water pipes do not release harmful substances or affect the quality and safety of water.

     Laboratory water: In scientific research laboratories, when using high-purity water for experiments, it is necessary to ensure that the water pipes do not affect the experimental results. Therefore, biocompatibility is a key factor.

     In applications where biocompatibility needs to be considered, water pipes made of the following materials are usually recommended:

     Stainless steel: Stainless steel is a material with good biocompatibility and is widely used in medical facilities, laboratories, and drinking water systems, especially in occasions with high requirements for water quality. Stainless steel has excellent corrosion resistance and anti-biofouling properties and is not easy to release harmful substances.

     Polyethylene (PE): Polyethylene is a plastic material with good biocompatibility and is usually used for cold water supply pipelines such as household water systems. It does not corrode and does not release harmful substances, but it is necessary to ensure that the selected polyethylene pipeline meets food-grade or medical-grade standards to ensure safety.

     Polypropylene (PP): Polypropylene is another common plastic material and is usually used in water supply and drainage systems. It performs well in general water treatment applications, but it also needs to ensure that it meets applicable food-grade or medical-grade standards.

     Polytetrafluoroethylene (PTFE): Polytetrafluoroethylene is an extremely biocompatible plastic and is usually used in special applications for transporting high-purity water and chemicals. It has excellent chemical inertness and corrosion resistance.
