Question

which type of pipe or tubing has the same dimensions as steel pipe of the same nominal size? options: pe/pex tubing, pvc pipe, type l copper tubing, type k copper tubing

Explanation:

To determine which pipe/tubing has the same dimensions as steel pipe of the same nominal size, we analyze each option:

• PE/PEX tubing: Typically has different sizing standards compared to steel pipe.
• PVC pipe: PVC pipes (specifically schedule 40 or 80 PVC) are designed to have the same nominal size dimensions as steel pipes for compatibility in plumbing and piping systems, especially for outer diameter and fitting compatibility.
• Type L copper tubing: Copper tubing (Type L or K) has different sizing conventions (measured by outer diameter and wall thickness in a way that doesn't match steel pipe nominal sizing for direct dimension matching).
• Type K copper tubing: Similar to Type L, it has a different sizing system than steel pipe for nominal size dimension matching.

So, PVC pipe is the correct choice as it is manufactured to match the nominal size dimensions of steel pipe for interchangeable use in many piping applications.

Answer:

B. PVC pipe
