MDPE (Medium Density Polyethylene) Tee water pipe fittings are commonly used in water supply systems to connect and branch off pipes in a three-way direction. These fittings are designed to withstand high pressure and are made from a durable material that is resistant to corrosion, chemicals, and UV radiation. They are commonly used in both domestic and industrial applications. The following are the sizes of MDPE Tee water pipe fittings and their uses: 20mm MDPE Tee: This size is commonly used for domestic water supply systems, irrigation systems, and sprinkler systems. 25mm MDPE Tee: This size is commonly used for water mains, agricultural irrigation systems, and sprinkler systems. 32mm MDPE Tee: This size is commonly used for water mains, agricultural irrigation systems, and sprinkler systems. 40mm MDPE Tee: This size is commonly used for water mains, industrial water supply systems, and agricultural irrigation systems. 50mm MDPE Tee: This size is commonly used for water mains, industrial water supply systems, and agricultural irrigation systems. In general, MDPE Tee water pipe fittings are used in situations where a pipe needs to be split off into two or more directions. They are easy to install and can be used with a variety of pipe materials, including MDPE, HDPE, and PVC pipes. They are also available in a range of other sizes to suit specific applications.
