This is a case history of laying a double wall steel pipeline, φ830×16mm +φ720×9mm, across a river, giving some details about the method of calculation, steps and precautions taken in the construction. Fix a center of oircle to form a radial ditch track before sinking the pipe. Then fill the pipe with water, and under negative buoyancy and horizontal push of water flow, settle down the pipe in the ditch on the river bed. This method is simple, reliable, accurate, economic and practical, applicable to river crossing of all kinds of oil and gas pipelines with specific gravity of empty pipe less than 1, without previous reinforcement treatment. It was used with success in crossing the Nenjiang River in Northeastern China.
