30mm vs 25mm vs 40mm — Which Should I Choose?

25mm wall is typically specified for smaller bore pipework and condensation control applications. 30mm is the step up for medium-bore commercial heating pipework where BS 5422 requires a thicker section. 40mm is specified for larger bore pipework and more demanding industrial applications.
