发明名称 RIGID PIPE CONNECTION AND METHOD OF MAKING THE SAME
摘要 A pipe connector has a pin initially stabbed into a box, the pin and box then being axially loaded together at confronting transverse surfaces while the pin and box are pressurized to expand the box and compress the pin, so that when the pressure is relieved a pressure energized shrink fit is provided and the connector is rendered rigid to enhance tensile, compressive and bending strength and provide a fluid tight joint useful in making up lengths of pipe such as piles and pipelines.
