How to choose the appropriate diameter of PPR pipes?When choosing the appropriate diameter of PPR (Polypropylene Random Copolymer) pipes, the following factors need to be considered:1. Flow Rate RequirementsCalculation of Flow Rate: First, determine the expected flow rate of the fluid (usually water

PPR pipes are usually manufactured through an extrusion process. The raw polypropylene random copolymer material is heated and forced through a die to form the desired pipe shape. During the manufacturing process, strict quality control measures are often implemented to ensure the pipes have consistent dimensions, wall thickness, and mechanical properties. Some manufacturers may also add additives such as UV stabilizers (for outdoor or exposed applications) and colorants to give the pipes specific properties or appearances.
