Q

Tubing is sized by __________.

🔍 Key Concepts

• Difference between how pipe and tubing are commonly specified in marine and industrial systems • Relationship between inside diameter (ID), outside diameter (OD), and wall thickness • Why system pressure rating is not the primary sizing reference for tubing

💭 Think About

• Think about how you would order a length of metal tubing from a supplier: what basic dimensional information do they ask for first? • Consider whether flow capacity in tubing systems is usually calculated from the inside or outside measurement, and which one stays more consistent across wall thickness changes. • Ask yourself: in practice, can the same size designation of tubing come with different pressure ratings depending on material and wall thickness?

✅ Before You Answer

• Be clear on the difference between nominal size and exact measured size. • Recall that pipe is traditionally sized differently from tubing—focus on what is standard for tubing, not pipe. • Verify whether the critical dimension for tubing selection is typically inside or outside diameter in standard specs/catalogs.
