Which of the following describes galvanized bending quality pipe?

• A. A glass lined pipe
• B. Treated in a special way to prevent flaking
• C. Pipe that is required to be cleaned free of rust
• D. Thoroughly cleaned with a protective coating

Answer: (B)

Galvanized bending quality pipe is specifically treated to prevent flaking, which is crucial in maintaining the pipe's integrity during bending and subsequent use. The galvanization process involves coating the pipe with a layer of zinc, which not only protects it from corrosion but also helps to ensure that the coating remains intact during the bending process. If the zinc layer were to flake off, it could lead to weaknesses in the pipe and potential failure during use.

Other options describe different aspects of pipe characteristics or treatments not specifically related to the definition of galvanized bending quality pipe. For instance, while there are requirements for cleaning pipes free of rust or applying protective coatings, these processes do not capture the essence of what makes the bending quality pipe specifically galvanized and designed to prevent flaking. Thus, the emphasis on preventing flaking is what makes option B the correct choice.
