Abstract

Bending Test and Simulation of Welded Galvanized Steel Pipes

Highlights

  • Galvanized steel pipes are widely used in industry and in constructional works [1]

  • Experimental and finite element (FE) studies were carried out to investigate the behaviour of welded A53 B galvanized pipes subjected to bending loading

  • Material properties of the pipe material and the weld metal which were used in the FE analysis are given in Tab. 2

Summary

INTRODUCTION

Galvanized steel pipes are widely used in industry and in constructional works [1] Typical application of these pipes is in fluid transfer, power plants piping, high pressure and low-pressure boiler tubes, petroleum cracking, scaffolding, etc. Rafiqul et al [5] studied the effects of the heat input on the mechanical properties of the welded galvanized steel pipes They concluded that the metal inert gas (MIG) is suitable for welding galvanized steel pipes. In many applications, galvanized steel pipes are welded together to have longer pipes These welded pipes could be subjected to tensile, compression, bending or torsional loading. A set of sub-size tensile specimens were cut of a third pipe piece Those specimens were used to measure the mechanical properties of the pipe material. The FE analyses succeeded to predict the loading capacity of the welded pipes accurately
