Summary
The purpose of this document is to propose a piping tee dimension definition for standard tee- and custom designed tee calculation in EN 13480-3.
The previous proposal with a straight-line distance definition for the limits, from the run side and branch side, resulted in significant differences with the EN 10253-2/4 approach. The limits are the lines that define borders of the pressure area and the material area in the calculation in Clause 8.

Introduction
The EN 13480-3 scope is specified as ‘the design and calculation of industrial metallic piping systems, including supports. The design criteria, as laid out in clause 4, include the internal and/or external pressure amongst others

The dimensions standard EN 10253-2 (and also EN 10253-4) have further detailed the calculations of EN 13480-3. The EN 10253-2 calculations are based on the EN 13480-3 but tailored to the EN 10253-2 fittings.The fitting types are elbow, tee, reducer and cap. The calculations are now part of our E80 application.

There are cases with manhole blind flanges where the number of bolts are not enough for a proper leak tight connection with the flange at the storage tank side. The blind flange takes the shape as an ‘umbrella’ around the bolts.

This document is for discussion, comments and suggestions. The purpose is to demonstrate the dimensions of the 42” 150# flange in relation to bolt load requirements for leak tightness. The 300# flange is used to illustrate the differences and the cause for possible tightness problems in case a spiral wound gasket is used

Introduction
This document is for discussion, comments and suggestions. The purpose is to compare and validate the EN 10253-2/4 strength calculation in B.4.4 and B.5.3 with the EN 13480-3 Clause 8. The EN 10253-2/4 indicate that the calculations are based on the EN 13480-3. This document highlights possible differences.

There is sometimes confusion about the joint efficiency when you compare the ASME B31.1 and the ASME B31.3. The joint efficiency for the ASME B31.1 (2020) are included in the allowable stress values of Table A-1 (US Customary units). Be careful, because some tables are also available is SI or metric units.
