What is the minimum bending radius of a polyethylene plastic pipe?

• A. 20 times pipe diameter
• B. 25 times pipe diameter
• C. 30 times pipe diameter
• D. 35 times pipe diameter

Answer: (C)

The minimum bending radius of a polyethylene plastic pipe is crucial for preventing damage to the pipe during installation and operation. A radius of 30 times the pipe diameter is widely recommended in the industry. This specification ensures that the pipe is not overly stressed or deformed during bending, which could lead to kinking, cracking, or other integrity issues. Polyethylene has a degree of flexibility, but if the bend exceeds the minimum radius, it may compromise the structural integrity of the pipe. Such bending can lead to stress concentrations and eventual failure, which is why following this guideline is important for maintaining a reliable plumbing system. Choosing a bending radius lesser than 30 times the pipe diameter increases the risk of mechanical failure during service, thus adhering to the proper minimum ensures durability and performance in various applications.
