Efficient methods of preheating in welding joints in pipelines

Pages 155-159 | Published online: 03 Nov 2011
 

Abstract

Various methods of heating in welding of pipelines are investigated. It is recommended to prepare an addition to the normalization–technical documents, in order to expand the range of application of KEN-type electric heaters in preheating and various types of electric resistance heaters, and also to remove stringent requirements on the control of preheat temperature from these documents.

Notes

1. Instructions for welding the Bovanenkovo–Ukhta transmission gas pipeline with a working pressure of 11.8 MPa inclusive, Part I, Gazprom, 2008.
