20090194717 | HIGH-PRESSURE VALVE ASSEMBLY - A high-pressure valve assembly includes a flange defining an axis. Projecting into the flange is a valve body which is sealed against the flange by a static ring seal. Provided on one side of the valve body is a spring-loaded closure member which is supported for movement in a direction of the axis to form a suction valve, and on another side of the valve body in opposition to the one side is a spring-loaded tappet which is supported for movement in the direction of the axis to form a pressure valve. A channel connects the suction valve with the pressure valve and has one end porting into a pressure chamber of the valve body adjacent to the pressure valve. The pressure chamber extends in axial direction of the tappet and is sized to extend substantially above a bottom edge of the ring seal. | 08-06-2009 |

20100326557 | METHOD FOR THE PRODUCTION OF HOT-FINISHED SEAMLESS PIPES HAVING OPTIMIZED FATIGUE PROPERTIES IN THE WELDED STATE - The invention relates to a method for the production of hot-finished, particularly hot-rolled, seamless pipes having optimized fatigue properties in the welded state, having an outside diameter of up to 711 mm and a nominal wall thickness of up to 100 mm, made of metal, in particular steel. After hot or finish rolling, a defined pipe cross-section is produced on at least one pipe end across a predetermined length, having tight tolerances for inside and outside diameters, wherein the cross-section can then be welded to the pipe end of another pipe. According to the invention, in a region a wall thickness is created in a first step at the pipe end in question, the thickness being bigger than on the remaining pipe body, wherein the outside diameter is increased and/or the inside diameter is reduced. In a second step, the required pipe cross-section is produced in said region by mechanical treatment, and the transition from the treated to the untreated region of the pipe is produced with low surface roughness and almost notch-free, and the residual wall thickness remaining in the treatment region is within the required tolerances. | 12-30-2010 |
