Modular Pipe Shoes Technical Supplement
1.0 INTRODUCTION
Hilti pipe shoes are devices that support and guide pipelines , which can expand or contract due to changes in temperature or pressure . Hilti pipe shoes typically consist of a base or saddle that sits on a supporting structure such as a beam or a pipe support , and a clamping mechanism that secures the pipeline in place . The clamping mechanism may include bolts or a clamp that wraps around the pipe , or a clamp that attaches to a flange or a weld pad welded to the pipe . Pipe shoes are typically used in piping systems in industrial facilities such as chemical plants , refineries , and power . plants . They help prevent excessive stress on the pipeline , which could result in leaks or failure . Pipe shoes can also be used to prevent abrasion or damage to the pipeline caused by contact with other structures or equipment . The design of a pipe shoe will depend on factors such as the size and type of pipeline , the temperature and pressure of the fluid being transported , and the location of the pipeline within the facility . Pipe shoes are typically made of materials such as carbon steel , stainless steel , or other alloys that can withstand the conditions of the piping system .
1.1 GENERAL INFORMATION FOR LOAD TABLES
A probabilistic approach is followed when testing is used to derive Allowable Loading ( ASD ), Design Strength ( LRFD ), and Limit State ( LSD ) values utilizing safety factors and resistance values as applicable . Published technical data loading tables are based on static loading conditions only . All non-static forces must be considered separately . Service loads were not considered .
The tabulated values for the pipe shoes and connectors as listed in this product technical guide are a combination of physical tests and analytical calculations . They do not include local effects , bending , web crippling , shear or buckling of a supporting member . These limit states must be checked independently .
1.2 PUBLISHED LOAD VALUES
