چکیده
The mobile pipeline is the most effective and reliable means for emergency oil transfer task, which temporarily laid on field. After completing in should be emptied before removed. gradually displaced by air a main method of evacuation, only choice jet fuel pipeline. Due to convection between gas phases, length oil–gas mixing section evolution interface change with time. gas–liquid directly determines different flow patterns two are very important evacuation. In this paper, characteristics during water studied, using multi-phase experiment. Through initial stage cap it found that can divided into smooth, wavy, dispersed forms under rates inclination angles. Slug phenomenon may occur process gas-carrying liquid emergence slug mainly affected hydraulic conditions operating conditions. plug body complex unstable, there will mutual transition shapes. increase angle phase velocity accelerate occurrence frequency.

Experimental Study of the Residual Stresses in Girth Weld of Natural Gas Transmission Pipeline
In order to achieve integrated condition in the girth welding of high pressure natural gas transmission pipelines, the weld zones and its surrounding area should have good mechanical properties. Residual stresses are an important defect especially in the girth welding of the pipeline. In this study, two API X70 steel pipes (with spiral seam weld) of 56 inches outside diameter and 0.780 inch wal...
