Water pipe is a material that many people care about, and usually everyone can understand only the main material part. As for water pipe fittings, water pipe auxiliary materials, and sewer materials, almost no one understands, or there is no way to understand. Water pipes can be divided into water inlet pipes and drain pipes according to their functions. Everyone is familiar with and concerned about the water inlet pipe, but most of them do not know about the drainage pipe. In fact, the drainage pipe is also very important. The water inlet pipe is generally used for household water inlet, and the PPR water inlet pipe is commonly used in the market. Because the water inlet involves issues such as environmental protection, pressure resistance, hot melt, etc., so for the selection of the water inlet pipe, we must pay attention to the indicators in this regard . The water inlet pipes commonly used in apartments are 25mm (6 points), and 32mm (1 inch) are generally used for a section of the main pipe, which will be used on different floors. Drainage pipes are generally used for household drainage. Now, PVC drainage pipes are commonly used in the market. There are not too many requirements for the selection of drainage pipes. Therefore, we only need to pay attention to the characteristics of the water pipes themselves. According to the specifications, the drainage pipes are usually divided into 40mm, 50mm, 75mm, 110mm, etc. The 40mm pipes are generally used for sink water, floor drain and balcony water; 50mm pipes are generally used for kitchen water; The total drainage of the basin, etc.; 110mm is generally used for toilet water and external wall water.
