The Design and Calculation on In-line Welding Branch Pipeline in Gas Transmission Trunk Line

The method of design and calculation on in-line welding branch pipeline for gas transmission trunk line is introduced. Take the in-line welding branch pipeline in gas transmission trunk line as an example, which has been carried out in Kuwait Gas Gathering Project, the paper presents the calculation on the compensation of in-line welding and the verification on loading-bearing capacity of the pipeline.
