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.

Design and engineering requires hands-on experience. The engineering calculations are difficult to assess without this experience. Although Red-Bag is a software company we believed this experience is crucial to giving adequate support to our customers. Red-Bag is finalizing the calculation software as per EN1591-2014. This calculation method is very detailed and complex. The Red-Bag software engineers together with engineers of Gasunie followed the course of flange management at Dijkgraaf-Support B.V. The images give an overview of the practical exercises supporting the theory as presented in the class room.
