LOKRING Design Guide

A Guideline for Designing ASME B31 Pressure Piping Using Lokring Fittings with ESP Technology

LOKRING ASME B31 Design Guide

The B31 simplified requirements were developed with and retain a focus on high-pressure, high-temperature piping which is typically welded or flanged. ASME B31 simplified rules are not developed as thoroughly regarding the design, manufacture, and installation of safe piping systems using non-welded, proprietary fittings (nonstandard components), such as the Lokring™ fitting with Elastic Strain Preload® (ESP®) technology.

However, there are B31 rules developed for pressure design and the development of stress multipliers (stress intensification factors) for nonstandard components that will allow the organization using Lokring fittings to develop a B31-compliant design.
