Guide: Dimension table for stainless steel pipes

By Colly Flowtech

Stainless steel pipe fittings in various sizes

What is a dimension table?

A dimension table shows standardized dimensions for pipes and fittings so you can quickly find the right dimension for your application.

What measurement standards are included?

The table includes common standards: DIN, SMS, ISO, OD (inch/outer diameter) and ANSI.

How do I calculate the inside diameter?

Use the formula: ID = YD - (wall thickness × 2). Example: YD 38.0 mm and wall 1.5 mm → ID = 38.0 - 3.0 = 35.0 mm.
