When it comes to home decoration, water pipes are one of the most essential components. Choosing the right type during the purchase process is crucial because a leak can lead to serious problems later on. Here's what you need to know about buying water pipes for your home. 1. In residential plumbing, common types of water pipes include PPR (Polypropylene Random), steel-plastic, and copper pipes. Steel-plastic pipes tend to be more expensive than PPR pipes, which in turn are pricier than traditional steel-plastic options. Copper pipes are the most costly, often costing around four times as much as PPR pipes. 2. When laying pipes during home renovation, it’s best to install them along the ceiling or walls rather than under the floor. Although this might slightly increase material costs, it makes future maintenance and repairs much easier and more accessible. 3. Hot and cold water pipes have different wall thicknesses. Cold water pipes are not suitable for hot water use. A quick way to identify hot water pipes is by looking for a red line marking on the surface. 4. The standard length of PPR pipes is typically 4 meters per piece. When purchasing, make sure to ask whether the price is per pipe or per meter. Once delivered, always check that the actual length matches what was ordered. 5. When selecting water pipes for your home, pay attention to both the diameter and wall thickness. For general use, a 6-point pipe is recommended, while a 4-point pipe may be sufficient for smaller areas. To ensure adequate water flow, using a 6-point pipe is often the safer choice. 6. When buying pipes, check if the inner diameter is uniform. An uneven inner diameter can cause issues when connecting fittings, leading to potential leaks or poor performance. 7. According to the "Construction and Decoration Engineering Quality Standard" from the Building Decoration Industry Association, newly installed water supply pipelines must undergo a pressure test. For metal and composite pipes, the test pressure should be 0.6MPa, held for 10 minutes with a pressure drop no more than 0.02MPa and no leakage. For plastic pipes, the pressure should be 0.8MPa, maintained for 20 minutes, with a pressure drop not exceeding 0.05MPa and no leaks detected. A water bath is a laboratory equipment used to incubate samples in a controlled temperature environment. It consists of a container filled with water that is heated to a specific temperature and maintained at that temperature. The sample is placed in a separate container that is submerged in the water bath, allowing for the sample to be heated or cooled to the desired temperature. Water baths are commonly used in biology, chemistry, and medical laboratories for a variety of applications including cell culture, enzyme reactions, and melting point determination.
