| The present invention relates to piping (1) for use in industrial activities, where the piping (1) has a specific geometry. In particular, the piping (1) is formed as a low amplitude helix, which causes fluid flowing through the piping (1) to swirl. This swirl flow provides a large number of advantages. Particular applications where the piping (1) can be used include incinerators and furnaces for waste disposal. | ||||||

| PROBLEM TO BE SOLVED: To reduce the risk of airlocks and the like in tubing or piping for carrying a multiphase flow.SOLUTION: Tubing or piping for carrying a multiphase flow is provided with means for inducing swirl flow, such that the denser components of the flow tend to the outer wall of the tubing or piping, and less dense components tend to the center of the tubing or piping. The flow thus exhibits a "centrifuge effect", which prevents lighter or heavier components of the flow from accumulating in upper or lower regions respectively of the tubing or piping, and reduces the risk of airlocks and the like. Preferably, the tubing or piping is in the form of a helix, which may be a low amplitude helix. | ||||||

| PURPOSE: To obtain the rock drill having a helically extending conveying groove for surely guiding a rock drill in a drill hole during the drilling work and causing only slight friction between the drill hole and an inner wall of the drill hole. CONSTITUTION: A rock drill includes a drill head 1, a shank 2 and a chuck end 3 located at an opposite position to the drill head 1. The shank 2 includes at least one helically extending conveying groove 4 and 5. Grooves 8 and 9 extending perpendicularly to the shank axis are formed in the top surface 6 and 7 of the helically extending conveying groove 4 and 5. | ||||||

| PURPOSE: To improve the sealing property by inserting an insert pin provided with a lock pin energized outward by the spring force and a seal member into an insert end provided with a corresponding seal member and a receiver hole for lock pin. CONSTITUTION: An insert pin 6 is fixed to an inside polygonal part 5 of a central pipe 2 of a water pipe 1. An O-shaped seal ring is provided at an end of the pin 6, and a lock pin 12 is provided right in front of the moving range from a length block A to a block B, and the pin 12 is energized outward by a plate spring 15, and the pin 12 is provided with an O-shaped seal ring 14. When connecting the pin 6 of the central pipe 2 to the water pipe 1, the moving range 24 inside of the water pipe 1 cooperates with the ring 10 so as to form a seal surface, and a notch 27 provided in a wall 26 cooperates with the pin 12 for lock. Consequently, sealing property is improved. COPYRIGHT: (C)1990,JPO | ||||||

| PURPOSE: To reduce torque required to rotate a drill string by forming at least one spiral groove on a main body part of a drill string member, so that the spiral groove defines a land on the main body part during flight. CONSTITUTION: A drill string member 14 is defined by an inside diameter 28 and an outside diameter 30, and has three spiral grooves 24. Residual parts of continuous lines are called lands, and they are parts of the member 14 to make contact with a bore hole in using. Compression stress is give to a surface 32 of the bottom part of the groove 24 by shot peening, etc. Consequently, mud moves around a drill string, and it is possible to improve a stirring effect and to extensively improve efficiency of drilling work. | ||||||
